It seems like this should just be a regular machine driver like other platforms have, were it not for that this would be mostly fine apart from a couple of nitpicks below. > +config SND_SOC_ROCKCHIP_MAX98090 > + tristate "ASoC support for Rockchip boards using a MAX98090 codec" > + depends on SND_SOC_ROCKCHIP && I2C && GPIOLIB > + select SND_SOC_ROCKCHIP_I2S > + select SND_SOC_MAX98090 > + select SND_SOC_TS3A227E This looks like it's a driver specific to Chromebooks (possibly even specific Chromeooks) and so should be named as such. > + card->dapm.idle_bias_off = true; Just set this when declaring the card, don't do it at runtime. > + snd_soc_dapm_enable_pin(dapm, "Headset Mic"); > + snd_soc_dapm_enable_pin(dapm, "Headphone"); > + snd_soc_dapm_enable_pin(dapm, "Speaker"); > + snd_soc_dapm_enable_pin(dapm, "Int Mic"); No need to do this, all pins are enabled by default. > + snd_soc_dapm_sync(dapm); This has no effect during initialization. -------------- next part -------------- A non-text attachment was scrubbed...
