2021-11-26ASoC: tegra: Use normal system sleep for MixerSameer Pujar
The driver currently subscribes for a late system sleep call. The initcall_debug log shows that suspend call for Mixer device happens after the parent device (AHUB). This seems to cause suspend failure on Jetson TX2 platform. Also there is no use of having late system sleep specifically for Mixer device. Fix the order by using normal system sleep.

2021-11-18ASoC: tegra: Fix kcontrol put callback in MixerSameer Pujar
The kcontrol put callback is expected to return 1 when there is change in HW or when the update is acknowledged by driver. This would ensure that change notifications are sent to subscribed applications. Filter out duplicate updates in Mixer driver.

2021-09-27ASoC: tegra: Constify static snd_soc_dai_ops structsRikard Falkeborn
The only usage of these is to assign their address to the ops field in the snd_soc_dai_driver struct, which is a pointer to const. Make them const to allow the compiler to put them in read-only memory.

2021-09-20ASoC: tegra: Add Tegra210 based Mixer driverSameer Pujar
The Mixer supports mixing of up to ten 7.1 audio input streams and generate five outputs (each of which can be any combination of the ten input streams) This patch registers Mixer driver with ASoC framework. The component driver exposes DAPM widgets, routes and kcontrols for the device. The DAI driver exposes Mixer interfaces, which can be used to connect different components in the ASoC layer. Makefile and Kconfig support is added to allow build the driver. It can be enabled in the DT via "nvidia,tegra210-amixer" compatible binding.
