Because we need to support the multiple codecs (MAX98357A/RT5514/DA7219)
on the RK3399 GRU boards, this patch can help us to support these codecs.

Changes in v5:
- fix the build warning for missing I2C/CLKDEV_LOOKUP dependency
Changes in v4:
- the compatible name needs to be based on a single reference design,
and the name of the board is called "GRU"
- use one i2sX card "rockchip,cpu = <&i2s0>" instead of array that is
based on GRU
- rename DOC to rockchip,rk3399-gru-sound.txt
- rename compatible to rockchip,rk3399-gru-sound
- rename source code to rk3399_gru_sound.c
Changes in v3:
- rename DOC to rockchip,rk3399-max98357a-rt5514-da7219.txt
- rename compatible to rockchip,rk3399-max98357a-rt5514-da7219
- rename source code to rk3399_max98357a_rt5514_da7219.c
Changes in v2:
- use the FS 256 to set mclks of the max98357a and rt5514 danamically
- add more sample rate for da7219

These seem fairly standard though a variety of versions in the bindings.
Can we use audio-codec and audio-cpu (or cpu or audio-dai) here? Mark?

Well, the roles aren't actually that standard (the fact that there's
multiple CODECs and one CPU DAI here is really odd and definitely needs
a very system specific interpretation). If they were standard we
already have the simple-card binding that things should be using.
There's no point in standard property names if the interpretation has to
be non-standard.
The vendor specific prefixes are there because all bindings are supposed
to add prefixes to property names.

Okay, I agree with the system specific interpretation part. However, I
don't think using simple-card or not determines using common

Should this also include SND_JACK_LINEOUT? da7219 differentiates
between the two so not including lineout means, for example, we can
miss jack insertion/removal events.

Hi Adam,
Could you please confirm Steve says that about SND_JACK_LINEOUT?
Thanks.

Hi Mark, I have a question for the one CPU DAI + multiple CODECs
setup. The machine driver defines 3 DAI links, connecting the same CPU
DAI to 3 different CODEC DAIs. Does ASoC/DAPM support
enabling/disabling an individual DAI link based on the status of the
endpoint widget (e.g. DAPM_SPK) connected to the corresponding CODEC?
The goal is to let user select either headphone(da7219) or
speaker(max98357a) as output. max98357a driver does not expose a
kcontrol for mute. It sets a shutdown GPIO on PCM_TRIGGER_START/STOP.
And it seems soc_pcm_trigger calls the trigger op of all 3 CODEC DAIs,
even when the DAPM_SPK widget is disabled by its pin switch.

Hi Xing Zheng,
Yes, as Steve mentioned DA7219 does support SND_JACK_LINEOUT so we should really
include this here.

The point here is that if those properties were to have a standard
meaning the system would be using simple-card anyway, the meaning is
entirely in the context of the card.
