Subject: [PATCH 1/7] ASoC: mediatek: mt8188: remove supply AUDIO_HIRES
Date:   Thu, 13 Apr 2023 18:47:07 +0800
Message-ID: <20230413104713.7174-2-trevor.wu@mediatek.com>
In-Reply-To: <20230413104713.7174-1-trevor.wu@mediatek.com>

AUDIO_HIRES is not required in MT8188. Because top_audio_h is disabled
when hires clock is not used, set_parent is a redundant operation.
