Subject: [PATCH v6 4/5] clk: imx: clk-audiomix: Add CLK_SET_RATE_PARENT flags for clocks
Date: Thu, 30 May 2024 10:31:17 +0800
Message-Id: <1717036278-3515-5-git-send-email-shengjiu.wang@nxp.com>
In-Reply-To: <1717036278-3515-1-git-send-email-shengjiu.wang@nxp.com>
References: <1717036278-3515-1-git-send-email-shengjiu.wang@nxp.com>
Precedence: bulk

Add CLK_SET_RATE_PARENT flags that when the device driver sets the
child clock rate, parent clock frequency can be refined accordingly.
