Currently, pcm512x driver supports only I2S data format. This commit adds RJ, LJ, DSP_A and DSP_B 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` Signed-off-by: Kirill Marinushkin <kmarinushkin@birdec.com> Cc: Mark Brown <broonie@kernel.org> Cc: Takashi Iwai <tiwai@suse.com> Cc: Liam Girdwood <lgirdwood@gmail.com> Cc: Matthias Reichl <hias@horus.com> Cc: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Cc: Peter Ujfalusi <peter.ujfalusi@ti.com> Cc: alsa-devel@alsa-project.org Cc: linux-kernel@vger.kernel.org --- sound/soc/codecs/pcm512x.c | 38 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+)
