Since commit a483dcbfa21f919c ("ARM: shmobile: lager: Remove legacy
board support"), R-Car Gen2 SoCs are only supported in generic DT-only
ARM multi-platform builds. The driver doesn't need to match platform
devices by name anymore, hence remove the corresponding
platform_device_id entry.

This series:
* adds support for interlaced video modes to the ipu-v3 driver
and dw_hdmi bridge.
* reworks the dw_hdmi connector enable/disable support, to ensure that
when DRM disables the output, it stays disabled irrespective of the
hotplug state.
* adds support for connector forcing, so we can force the hotplug state
for this connector.
* adds the ALSA AHB audio driver to the bridge: Iwai has acked the

audio on iMX6.

stable from the RCU point of view (and we might be on UP, etc), but
stale from the remote fs point of view. If ->d_revalidate() returns
"it's actually stale", dentry gets thrown away and the original code

->d_seq validation) but only use the result in cases where we do not
discard this dentry outright"

drm: bridge/dw_hdmi: replace CTS calculation for the ACR
Given the TDMS clock, audio sample rate, and the N parameter, we can
calculate the CTS value for the audio clock regenerator (ACR) using the
following calculation given in the HDMI specification:
CTS = ftdms * N / (128 * fs)
The specification says that the CTS value is an average value, which is
true if the source hardware measures it. Where source hardware needs it
to be programmed, it is particularly difficult to alternate between two
values correctly to ensure that we achieve a correct "average"
fractional value at the sink.
Also, there's the problem that our "ftdms" is not a fully accurate
value; it is rounded to a kHz value. This introduces an unnecessary
(and harmless) fractional value into the above equation for combinations
like 148.5MHz/1.001 for 44100Hz - we still calculate the correct CTS
value.

then incorrectly pops the bio from conf->bio_end_io_list (which is empty

It disables the internal clock which causes a reset mecanism. If we

the stabilisation of the internal clock, so a delay is needed. This
delay is about 2-3 cycles of the base clock. To be safe, a 1 ms delay is
used.
