+ADS1015 (I2C)
+
+This device is a 12-bit A-D converter with 4 inputs.
+
+The inputs can be used single ended or in certain differential combinations.
+
+For configuration all possible combinations are mapped to 8 channels:
+ 0: Voltage over AIN0 and AIN1.
+ 1: Voltage over AIN0 and AIN3.
+ 2: Voltage over AIN1 and AIN3.
+ 3: Voltage over AIN2 and AIN3.
+ 4: Voltage over AIN0 and GND.
+ 5: Voltage over AIN1 and GND.
+ 6: Voltage over AIN2 and GND.
+ 7: Voltage over AIN3 and GND.
+
+Each channel can be configured individually:
+ - pga is the programmable gain amplifier (values are full scale)
+ 0: +/- 6.144 V
+ 1: +/- 4.096 V
+ 2: +/- 2.048 V (default)
+ 3: +/- 1.024 V
+ 4: +/- 0.512 V
+ 5: +/- 0.256 V
+ - data_rate in samples per second
+ 0: 128
+ 1: 250
+ 2: 490
+ 3: 920
+ 4: 1600 (default)
+ 5: 2400
+ 6: 3300
+
+1) The /ads1015 node
+
+ Required properties:
+
+ - compatible : must be "ti,ads1015"
+ - reg : I2C bus address of the device
+ - #address-cells : must be <1>
+ - #size-cells : must be <0>
+
+ The node contains child nodes for each channel that the platform uses.
+
+ Example ADS1015 node:
+
+ ads1015@49 {
+ compatible = "ti,ads1015";
+ reg = <0x49>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ [ child node definitions... ]
+ }
+
+2) channel nodes
+
+ Required properties:
+
+ - reg : the channel number
+
+ Optional properties:
+
+ - ti,gain : the programmable gain amplifier setting
+ - ti,datarate : the converter data rate
+
+ Example ADS1015 channel node:
+
+ channel@4 {
+ reg = <4>;
+ ti,gain = <3>;
+ ti,datarate = <5>;
+ };

+* Open PIC Binding
+
+This binding specifies what properties must be available in the device tree
+representation of an Open PIC compliant interrupt controller. This binding is
+based on the binding defined for Open PIC in [1] and is a superset of that
+binding.
+
+Required properties:
+
+ NOTE: Many of these descriptions were paraphrased here from [1] to aid
+ readability.
+
+ - compatible: Specifies the compatibility list for the PIC. The type
+ shall be <string> and the value shall include "open-pic".
+
+ - reg: Specifies the base physical address(s) and size(s) of this
+ PIC's addressable register space. The type shall be <prop-encoded-array>.
+
+ - interrupt-controller: The presence of this property identifies the node
+ as an Open PIC. No property value shall be defined.
+
+ - #interrupt-cells: Specifies the number of cells needed to encode an
+ interrupt source. The type shall be a <u32> and the value shall be 2.
+
+ - #address-cells: Specifies the number of cells needed to encode an
+ address. The type shall be <u32> and the value shall be 0. As such,
+ 'interrupt-map' nodes do not have to specify a parent unit address.
+
+Optional properties:
+
+ - pic-no-reset: The presence of this property indicates that the PIC
+ shall not be reset during runtime initialization. No property value shall
+ be defined. The presence of this property also mandates that any
+ initialization related to interrupt sources shall be limited to sources
+ explicitly referenced in the device tree.
+
+* Interrupt Specifier Definition
+
+ Interrupt specifiers consists of 2 cells encoded as
+ follows:
+
+ - <1st-cell>: The interrupt-number that identifies the interrupt source.
+
+ - <2nd-cell>: The level-sense information, encoded as follows:
+ 0 = low-to-high edge triggered
+ 1 = active low level-sensitive
+ 2 = active high level-sensitive
+ 3 = high-to-low edge triggered
+
+* Examples
+
+Example 1:
+
+ /*
+ * An Open PIC interrupt controller
+ */
+ mpic: pic@40000 {
+ // This is an interrupt controller node.
+ interrupt-controller;
+
+ // No address cells so that 'interrupt-map' nodes which reference
+ // this Open PIC node do not need a parent address specifier.
+ #address-cells = <0>;
+
+ // Two cells to encode interrupt sources.
+ #interrupt-cells = <2>;
+
+ // Offset address of 0x40000 and size of 0x40000.
+ reg = <0x40000 0x40000>;
+
+ // Compatible with Open PIC.
+ compatible = "open-pic";
+
+ // The PIC shall not be reset.
+ pic-no-reset;
+ };
+
+Example 2:
+
+ /*
+ * An interrupt generating device that is wired to an Open PIC.
+ */
+ serial0: serial@4500 {
+ // Interrupt source '42' that is active high level-sensitive.
+ // Note that there are only two cells as specified in the interrupt
+ // parent's '#interrupt-cells' property.
+ interrupts = <42 2>;
+
+ // The interrupt controller that this device is wired to.
+ interrupt-parent = <&mpic>;
+ };

+Kernel driver ads1015
+=====================
+
+Supported chips:
+ * Texas Instruments ADS1015
+ Prefix: 'ads1015'
+ Datasheet: Publicly available at the Texas Instruments website :
+ http://focus.ti.com/lit/ds/symlink/ads1015.pdf
+
+Authors:
+ Dirk Eibach, Guntermann & Drunck GmbH <eibach@gdsys.de>
+
+Description
+-----------
+
+This driver implements support for the Texas Instruments ADS1015.
+
+This device is a 12-bit A-D converter with 4 inputs.
+
+The inputs can be used single ended or in certain differential combinations.
+
+The inputs can be made available by 8 sysfs input files in0_input - in7_input:
+in0: Voltage over AIN0 and AIN1.
+in1: Voltage over AIN0 and AIN3.
+in2: Voltage over AIN1 and AIN3.
+in3: Voltage over AIN2 and AIN3.
+in4: Voltage over AIN0 and GND.
+in5: Voltage over AIN1 and GND.
+in6: Voltage over AIN2 and GND.
+in7: Voltage over AIN3 and GND.
+
+Which inputs are available can be configured using platform data or devicetree.
+
+By default all inputs are exported.
+
+Platform Data
+-------------
+
+In linux/i2c/ads1015.h platform data is defined, channel_data contains
+configuration data for the used input combinations:
+- pga is the programmable gain amplifier (values are full scale)
+ 0: +/- 6.144 V
+ 1: +/- 4.096 V
+ 2: +/- 2.048 V
+ 3: +/- 1.024 V
+ 4: +/- 0.512 V
+ 5: +/- 0.256 V
+- data_rate in samples per second
+ 0: 128
+ 1: 250
+ 2: 490
+ 3: 920
+ 4: 1600
+ 5: 2400
+ 6: 3300
+
+Example:
+struct ads1015_platform_data data = {
+ .channel_data = {
+ [2] = { .enabled = true, .pga = 1, .data_rate = 0 },
+ [4] = { .enabled = true, .pga = 4, .data_rate = 5 },
+ }
+};
+
+In this case only in2_input (FS +/- 4.096 V, 128 SPS) and in4_input
+(FS +/- 0.512 V, 2400 SPS) would be created.
+
+Devicetree
+----------
+
+Configuration is also possible via devicetree:

-Description
------------
-
-This driver provides support for the accelerometer found in various HP laptops
-sporting the feature officially called "HP Mobile Data Protection System 3D" or
-"HP 3D DriveGuard". It detects automatically laptops with this sensor. Known
-models (full list can be found in drivers/hwmon/hp_accel.c) will have their
-axis automatically oriented on standard way (eg: you can directly play
-neverball). The accelerometer data is readable via
-/sys/devices/platform/lis3lv02d. Reported values are scaled
-to mg values (1/1000th of earth gravity).
-
-Sysfs attributes under /sys/devices/platform/lis3lv02d/:
-position - 3D position that the accelerometer reports. Format: "(x,y,z)"
-rate - read reports the sampling rate of the accelerometer device in HZ.
- write changes sampling rate of the accelerometer device.
- Only values which are supported by HW are accepted.
-selftest - performs selftest for the chip as specified by chip manufacturer.
-
-This driver also provides an absolute input class device, allowing
-the laptop to act as a pinball machine-esque joystick. Joystick device can be
-calibrated. Joystick device can be in two different modes.
-By default output values are scaled between -32768 .. 32767. In joystick raw
-mode, joystick and sysfs position entry have the same scale. There can be
-small difference due to input system fuzziness feature.
-Events are also available as input event device.
-
-Selftest is meant only for hardware diagnostic purposes. It is not meant to be
-used during normal operations. Position data is not corrupted during selftest
-but interrupt behaviour is not guaranteed to work reliably. In test mode, the
-sensing element is internally moved little bit. Selftest measures difference
-between normal mode and test mode. Chip specifications tell the acceptance
-limit for each type of the chip. Limits are provided via platform data
-to allow adjustment of the limits without a change to the actual driver.
-Seltest returns either "OK x y z" or "FAIL x y z" where x, y and z are
-measured difference between modes. Axes are not remapped in selftest mode.
-Measurement values are provided to help HW diagnostic applications to make
-final decision.
-
-On HP laptops, if the led infrastructure is activated, support for a led
-indicating disk protection will be provided as /sys/class/leds/hp::hddprotect.
-
-Another feature of the driver is misc device called "freefall" that
-acts similar to /dev/rtc and reacts on free-fall interrupts received
-from the device. It supports blocking operations, poll/select and
-fasync operation modes. You must read 1 bytes from the device. The
-result is number of free-fall interrupts since the last successful
-read (or 255 if number of interrupts would not fit). See the hpfall.c
-file for an example on using the device.
-
-
-Axes orientation
-----------------
-
-For better compatibility between the various laptops. The values reported by
-the accelerometer are converted into a "standard" organisation of the axes
-(aka "can play neverball out of the box"):
- * When the laptop is horizontal the position reported is about 0 for X and Y
- and a positive value for Z
- * If the left side is elevated, X increases (becomes positive)
- * If the front side (where the touchpad is) is elevated, Y decreases
- (becomes negative)
- * If the laptop is put upside-down, Z becomes negative
-
-If your laptop model is not recognized (cf "dmesg"), you can send an
-email to the maintainer to add it to the database. When reporting a new
-laptop, please include the output of "dmidecode" plus the value of
-/sys/devices/platform/lis3lv02d/position in these four cases.
-
-Q&A
----
-
-Q: How do I safely simulate freefall? I have an HP "portable
-workstation" which has about 3.5kg and a plastic case, so letting it
-fall to the ground is out of question...
-
-A: The sensor is pretty sensitive, so your hands can do it. Lift it
-into free space, follow the fall with your hands for like 10
-centimeters. That should be enough to trigger the detection.

The new style binding model will check against a list of supported

the busses. This means that the driver .attach_adapter and
-.detach_adapter methods can be removed, along with the addr_data,
+.detach_client methods can be removed, along with the addr_data,
as follows:

static struct i2c_driver example_driver = {
- .attach_adapter = example_attach_adapter,
-- .detach_client = __devexit_p(example_detach),

Add the probe and remove methods to the i2c_driver, as so:

-+ .remove = __devexit_p(example_remove),
++ .remove = example_remove,

Change the example_attach method to accept the new parameters
can also remove the ret variable as it is not not needed for
any of the core functions.

+
+Description
+-----------
+
+This driver provides support for the accelerometer found in various HP laptops
+sporting the feature officially called "HP Mobile Data Protection System 3D" or
+"HP 3D DriveGuard". It detects automatically laptops with this sensor. Known
+models (full list can be found in drivers/platform/x86/hp_accel.c) will have
+their axis automatically oriented on standard way (eg: you can directly play
+neverball). The accelerometer data is readable via
+/sys/devices/platform/lis3lv02d. Reported values are scaled
+to mg values (1/1000th of earth gravity).
+
+Sysfs attributes under /sys/devices/platform/lis3lv02d/:
+position - 3D position that the accelerometer reports. Format: "(x,y,z)"
+rate - read reports the sampling rate of the accelerometer device in HZ.
+ write changes sampling rate of the accelerometer device.
+ Only values which are supported by HW are accepted.
+selftest - performs selftest for the chip as specified by chip manufacturer.
+
+This driver also provides an absolute input class device, allowing
+the laptop to act as a pinball machine-esque joystick. Joystick device can be
+calibrated. Joystick device can be in two different modes.
+By default output values are scaled between -32768 .. 32767. In joystick raw
+mode, joystick and sysfs position entry have the same scale. There can be
+small difference due to input system fuzziness feature.
+Events are also available as input event device.
+
+Selftest is meant only for hardware diagnostic purposes. It is not meant to be
+used during normal operations. Position data is not corrupted during selftest
+but interrupt behaviour is not guaranteed to work reliably. In test mode, the
+sensing element is internally moved little bit. Selftest measures difference
+between normal mode and test mode. Chip specifications tell the acceptance
+limit for each type of the chip. Limits are provided via platform data
+to allow adjustment of the limits without a change to the actual driver.
+Seltest returns either "OK x y z" or "FAIL x y z" where x, y and z are
+measured difference between modes. Axes are not remapped in selftest mode.
+Measurement values are provided to help HW diagnostic applications to make
+final decision.
+
+On HP laptops, if the led infrastructure is activated, support for a led
+indicating disk protection will be provided as /sys/class/leds/hp::hddprotect.
+
+Another feature of the driver is misc device called "freefall" that
+acts similar to /dev/rtc and reacts on free-fall interrupts received
+from the device. It supports blocking operations, poll/select and
+fasync operation modes. You must read 1 bytes from the device. The
+result is number of free-fall interrupts since the last successful
+read (or 255 if number of interrupts would not fit). See the hpfall.c
+file for an example on using the device.
+
+
+Axes orientation
+----------------
+
+For better compatibility between the various laptops. The values reported by
+the accelerometer are converted into a "standard" organisation of the axes
+(aka "can play neverball out of the box"):
+ * When the laptop is horizontal the position reported is about 0 for X and Y
+ and a positive value for Z
+ * If the left side is elevated, X increases (becomes positive)
+ * If the front side (where the touchpad is) is elevated, Y decreases
+ (becomes negative)
+ * If the laptop is put upside-down, Z becomes negative
+
+If your laptop model is not recognized (cf "dmesg"), you can send an
+email to the maintainer to add it to the database. When reporting a new
+laptop, please include the output of "dmidecode" plus the value of
+/sys/devices/platform/lis3lv02d/position in these four cases.
+
+Q&A
+---
+
+Q: How do I safely simulate freefall? I have an HP "portable
+workstation" which has about 3.5kg and a plastic case, so letting it
+fall to the ground is out of question...
+
+A: The sensor is pretty sensitive, so your hands can do it. Lift it
+into free space, follow the fall with your hands for like 10
+centimeters. That should be enough to trigger the detection.
Note: No module for the mse3000 is available yet
Note: No module for the vpx3224 is available yet
-Note: use encoder=X or decoder=X for non-default i2c chips (see i2c-id.h)

+ * The touchscreen interface operates as follows:
+ *
+ * 1) Pen is pressed against the touchscreen.
+ * 2) TSC2005 performs AD conversion.
+ * 3) After the conversion is done TSC2005 drives DAV line down.
+ * 4) GPIO IRQ is received and tsc2005_irq_thread() is scheduled.
+ * 5) tsc2005_irq_thread() queues up an spi transfer to fetch the x, y, z1, z2
+ * values.
+ * 6) tsc2005_irq_thread() reports coordinates to input layer and sets up
+ * tsc2005_penup_timer() to be called after TSC2005_PENUP_TIME_MS (40ms).
+ * 7) When the penup timer expires, there have not been touch or DAV interrupts
+ * during the last 40ms which means the pen has been lifted.
+ *
+ * ESD recovery via a hardware reset is done if the TSC2005 doesn't respond
+ * after a configurable period (in ms) of activity. If esd_timeout is 0, the
+ * watchdog is disabled.

# With BISECT_REVERSE = 1, The test will consider failures as
# good, and success as bad.
#
+# BISECT_MANUAL = 1 (optional, default 0)
+#
+# In case there's a problem with automating the bisect for
+# whatever reason. (Can't reboot, want to inspect each iteration)
+# Doing a BISECT_MANUAL will have the test wait for you to
+# tell it if the test passed or failed after each iteration.
+# This is basicall the same as running git bisect yourself
+# but ktest will rebuild and install the kernel for you.
+#
# BISECT_CHECK = 1 (optional, default 0)
#
# Just to be sure the good is good and bad is bad, setting
#
# CONFIG_BISECT is the config that failed to boot
#
+# If BISECT_MANUAL is set, it will pause between iterations.
+# This is useful to use just ktest.pl just for the config bisect.
+# If you set it to build, it will run the bisect and you can
+# control what happens in between iterations. It will ask you if
+# the test succeeded or not and continue the config bisect.
+#
# Example:
# TEST_START
# TEST_TYPE = config_bisect
# CONFIG_BISECT_TYPE = build
# CONFIG_BISECT = /home/test/¢onfig-bad
# MIN_CONFIG = /home/test/config-min
+# BISECT_MANUAL = 1
