This provides commonly used APIs for input/output control registers for UniPhier AIO. This module provides all sound devices for I2S, S/PDIF and so on. Since the AIO has mixed register map for those I/Os, it is hard to split register areas for each sound devices. Signed-off-by: Katsuhiro Suzuki --- Changes in v2: - Change license comment style to C++ from C - Split DMA, DAI patches from large one - Fix bad name 'srcport' to 'src' - Add members to struct uniphier_aio_sub and add methods for compress audio - Change to void if function has no fail --- sound/soc/uniphier/Kconfig | 10 + sound/soc/uniphier/Makefile | 4 + sound/soc/uniphier/aio-core.c | 1104 +++++++++++++++++++++++++++++++++++++++++ sound/soc/uniphier/aio-reg.h | 462 +++++++++++++++++ sound/soc/uniphier/aio.h | 343 +++++++++++++ 5 files changed, 1923 insertions(+) create mode 100644 sound/soc/uniphier/aio-core.c create mode 100644 sound/soc/uniphier/aio-reg.h create mode 100644 sound/soc/uniphier/aio.h -- 2.15.0 _______________________________________________ Alsa-devel mailing list Alsa-devel@alsa-project.org http://mailman.alsa-project.org/mailman/listinfo/alsa-devel diff --git a/sound/soc/uniphier/Kconfig b/sound/soc/uniphier/Kconfig index 02886a457eaf..78ce101d2cc2 100644 --- a/sound/soc/uniphier/Kconfig +++ b/sound/soc/uniphier/Kconfig @@ -8,6 +8,16 @@ config SND_SOC_UNIPHIER audio interfaces to support below.
