Donglin Peng dc94d245a5 ASoC: rockchip: Remove unnecessary function call
First of all,the address of pdev->dev is assigned to card->dev,then
the function platform_set_drvdata copies the value the variable card
to pdev->dev.driver_data, but when calling snd_soc_register_card,the
function dev_set_drvdata(card->dev, card) will also do the same copy
operation,so i think that the former copy operation can be removed.

Romain Perier eaae2ea735 ASoC: rockchip: Add machine driver for RK3288 boards that use analog/HDMI
The driver is used for Rockchip rk3288-based boards using a configurable
analog output (can be an headphone) and the built-in HDMI audio output
that is part of the RK3288 SoCs and use the Alsa HDMI codec driver. For
some rk3288-based boards the analog output and the hdmi audio are plugged
on the same i2s line, so we have to do the same in the driver by using a
DAI link CPU to multicodecs. This configuration can be found for example
on the Radxa Rock2 or the Firefly-RK3288.

Chris Zhong 46dd2e28a9 ASoC: rockchip: correct the spdif clk
The spdif mclk should be 128 times of sample rate, and there is a
internal divider, the real rate of spdif mclk is mclk / (div + 1).
Hence, the original driver always get the good frequency for
48000/96000/44100/192000. But for 32000, the mclk is incorrect,
it should be 32000*128, but get 48000*128. Do not use the internal
divider here, just set all mclk to 128 * sample rate directly.

Enric Balletbo i Serra 5f22449344 ASoC: rockchip-max98090: Fix NULL pointer dereference while accessing to jack.
Commit f2ed6b0764 ("ASoC: Make aux_dev more like a generic
component") caused a regression on this driver, since now a
kernel oops is seen when rockchip-mac98090 driver is loaded.

That commit changed the probing of aux_devs before checking
new DAI links, so for this driver rk_98090_headset_init is
called before rk_init and then the kernel oops due a NULL
pointer dereference inside rk_98090_headset_init function
since there is a call that tries to access the jack pointer
which has not been allocated yet.

This is the call chain that causes the crash:

 rk_98090_headset_init
   -> ts3a227e_enable_jack_detect
      -> snd_jack_set_key
 rk_init
   -> snd_soc_card_jack_new

This patch moves the new jack object creation from rk_init
to rk_98090_headset_init function making sure the jack is
created before is accessed.

Sjoerd Simons 5042f936c6 ASoC: rockchip: spdif: Set transmit data level to 16 samples
Explicitly set the transmit data level on the transceiver to 16 samples
rather then the default 0. This matches both the level set in the vendor
kernel and the (seemingly very similar) i2s engine. This fixes audio
glitches when playing back at 192k rate.

At the same time, fix a trivial typo in the TDL mask definition

John Keeping eba65d179c ASoC: rockchip: i2s: separate capture and playback
If we only clear the tx/rx state when both are disabled it is not
possible to start/stop one multiple times while the other is running.
Since the two are independently controlled, treat them as such and
remove the false dependency between capture and playback.

Sjoerd Simons 18a9d7486a ASoC: rockchip: Fix incorrect VDW value for 24 bit
Correct valid data word register value for 24 bit data width. The
bit value should be 10 (aka 0x2), not 0x10.

This fixes playback of 24 bit audio.

Sugar Zhang c4f9374ddc ASoC: rockchip: i2s: compatible with different chips
there maybe more than one i2s module inside chip, and these i2s modules
have different channels features.

for example: there are 3 i2s in rk3066, one support 8 channels playback
and 2 channels capture, but the others only support 2 channels playback
and 2 channels capture.

in order to compatible with these various chips, we add playback and
capture property to specify these values.

there are default channels configuration in driver: 8 channels playback
and 2 channels capture. if not add property, we use the default values.

Arnd Bergmann 0e18d457b3 ASoC: fix rockchip 64-bit build warning
The rk_spdif_probe uses the device match data as a token to identify a
particular device, but accidentally casts a pointer to 'int', which is
not portable, as gcc points out in this warning on arm64:

rockchip_spdif.c: In function 'rk_spdif_probe':
rockchip_spdif.c:283:6: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]

This changes the logic to compare two pointer values instead, using
the same cast that was used for initializing the value in the first
place.
