Subject: [PATCH v2 7/7] ASoC: dt-bindings: mediatek,mt8188-afe: add audio properties
Date:   Fri, 21 Apr 2023 18:09:05 +0800
Message-ID: <20230421100905.28045-8-trevor.wu@mediatek.com>
In-Reply-To: <20230421100905.28045-1-trevor.wu@mediatek.com>

Precedence: bulk

Assign top_a1sys_hp clock to 26M, and add apll1_d4 to clocks for switching
the parent of top_a1sys_hp dynamically
On the other hand, "mediatek,infracfg" is included for bus protection.
