ASoC: hdmi-codec: Remove redundant big endian formats

2022-05-09T11:46:14Z

The CODEC already provides the endianness flag on its snd_soc_component_driver structure, specifying it is ambivalent to endian. The core will expand the formats to cover both endian types, as such remove the redundant specification of both endians.

ASoC: hdmi-codec: Fix OOB memory accesses

2022-01-28T15:59:19Z

Correct size of iec_status array by changing it to the size of status array of the struct snd_aes_iec958. This fixes out-of-bounds slab read accesses made by memcpy() of the hdmi-codec driver. This problem is reported by KASAN. Cc: stable@vger.kernel.org Signed-off-by: Dmitry Osipenko Link: https://lore.kernel.org/r/20220112195039.1329-1-digetx@gmail.com Signed-off-by: Mark Brown

ASoC: hdmi-codec: make hdmi_codec_controls static

2021-06-16T14:41:14Z

This symbol is not used outside of hdmi-codec.c, so marks it static. Fix the following sparse warning: sound/soc/codecs/hdmi-codec.c:750:25: warning: symbol 'hdmi_codec_controls' was not declared. Should it be static? Reported-by: Abaci Robot Signed-off-by: Jiapeng Chong Link: https://lore.kernel.org/r/1623822941-3077-1-git-send-email-jiapeng.chong@linux.alibaba.com Signed-off-by: Mark Brown

Improvements to the hdmi-codec driver and ALSA infrastructure around it to support the HDMI Channel Mapping and IEC958 controls

ASoC: hdmi-codec: Add a prepare hook

2021-06-10T09:48:56Z

The IEC958 status bit is usually set by the userspace after hw_params has been called, so in order to use whatever is set by the userspace, we need to implement the prepare hook. Let's add it to the hdmi_codec_ops, and mandate that either prepare or hw_params is implemented.

ASoC: hdmi-codec: Add iec958 controls

2021-06-10T09:48:49Z

The IEC958 status bits can be exposed and modified by the userspace through dedicated ALSA controls. This patch implements those controls for the hdmi-codec driver. It relies on a default value being setup at probe time that can later be overridden by the control put. The hw_params callback is then called with a buffer filled with the proper bits for the current parameters being passed on so the underlying driver can just reuse those bits as is.

ASoC: hdmi-codec: Rework to support more controls

2021-06-08T15:05:47Z

We're going to add more controls to support the IEC958 output, so let's rework the control registration a bit to support more of them. Signed-off-by: Maxime Ripard Acked-by: Mark Brown Link: https://lore.kernel.org/r/20210525132354.297468-4-maxime@cerno.tech
