[PATCH] ASoC: fsl_sai: Add pm qos cpu latency support
by Shengjiu Wang 02 Mar '21

02 Mar '21

On SoCs such as i.MX7ULP, cpuidle has some levels which may disable system/bus clocks, so need to add pm_qos to prevent cpuidle from entering low level idles and make sure system/bus clocks are enabled when sai is active.

[PATCH] ASoC: constify of_phandle_args in snd_soc_get_dai_name()
by Krzysztof Kozlowski 02 Mar '21

02 Mar '21

The pointer to of_phandle_args passed to snd_soc_get_dai_name() and of_xlate_dai_name() implementations is not modified. Since it is being used only to translate passed OF node to a DAI name, it should not be modified, so mark it as const for correctness and safer code.
