Subject: [PATCH] ASoC: pcm512x: Add support for data formats RJ and LJ
Date: Mon, 9 Nov 2020 22:21:33 +0100 [thread overview]
Message-ID: <20201109212133.25869-1-kmarinushkin@birdec.com> (raw)
Currently, pcm512x driver supports only I2S data format.
This commit adds RJ and LJ as well.
I don't expect regression WRT existing sound cards, because:
* default value in corresponding register of pcm512x codec is 0 == I2S
* existing in-tree sound cards with pcm512x codec are configured for I2S
* i don't see how existing off-tree sound cards with pcm512x codec could be
configured differently - it would not work
* tested explicitly, that there is no regression with Raspberry Pi +
sound card `sound/soc/bcm/hifiberry_dacplus.c`
