| e3fffc1f | 1 | Marvell 8787/8897/8997 (sd8787/sd8897/sd8997/pcie8997) SDIO/PCIE devices |
| 84039920 XH |
2 | ------ |

| 6b4480d1 XH |
4 | This node provides properties for controlling the Marvell SDIO/PCIE wireless device. |
| 5 | The node is expected to be specified as a child node to the SDIO/PCIE controller that | |
| 84039920 XH |
6 | connects the device to the system. |
| 7 | ||
| 8 | Required properties: | |
| 9 | ||
| 10 | - compatible : should be one of the following: | |
| e3fffc1f | 11 | * "marvell,sd8787" |
| 84039920 XH |
12 | * "marvell,sd8897" |
| 13 | * "marvell,sd8997" | |
| 6b4480d1 XH |
14 | * "pci11ab,2b42" |
| 15 | * "pci1b4b,2b42" | |
| 84039920 XH |
16 | |
| 17 | Optional properties: | |
| 18 | ||
| 19 | - marvell,caldata* : A series of properties with marvell,caldata prefix, | |
| 20 | represent calibration data downloaded to the device during | |
| 21 | initialization. This is an array of unsigned 8-bit values. | |
| 22 | the properties should follow below property name and | |
| 23 | corresponding array length: | |
| 24 | "marvell,caldata-txpwrlimit-2g" (length = 566). | |
| 25 | "marvell,caldata-txpwrlimit-5g-sub0" (length = 502). | |
| 26 | "marvell,caldata-txpwrlimit-5g-sub1" (length = 688). | |
| 27 | "marvell,caldata-txpwrlimit-5g-sub2" (length = 750). | |
| 28 | "marvell,caldata-txpwrlimit-5g-sub3" (length = 502). | |
| 29 | - marvell,wakeup-pin : a wakeup pin number of wifi chip which will be configured | |
| 30 | to firmware. Firmware will wakeup the host using this pin | |
| 31 | during suspend/resume. | |
| 32 | - interrupt-parent: phandle of the parent interrupt controller | |
| 33 | - interrupts : interrupt pin number to the cpu. driver will request an irq based on | |
| 34 | this interrupt number. during system suspend, the irq will be enabled | |
| 35 | so that the wifi chip can wakeup host platform under certain condition. | |
| 36 | during system resume, the irq will be disabled to make sure | |
| 37 | unnecessary interrupt is not received. | |

38 | - vmmc-supply: a phandle of a regulator, supplying VCC to the card |
| 39 | - mmc-pwrseq: phandle to the MMC power sequence node. See "mmc-pwrseq-*" | |
| 40 | for documentation of MMC power sequence bindings. | |

| 42 | Example: | |
| 43 | ||
| 44 | Tx power limit calibration data is configured in below example. | |
| 45 | The calibration data is an array of unsigned values, the length | |
| 46 | can vary between hw versions. | |
| 47 | IRQ pin 38 is used as system wakeup source interrupt. wakeup pin 3 is configured | |
| 48 | so that firmware can wakeup host using this device side pin. | |
