Subject: [PATCH v1 2/4] dt-bindings: clock: rk3368: add CLK_I2S_8CH_PRE and CLK_I2S_8CH_FRAC
Date: Fri, 5 Sep 2025 21:23:26 +0800 [thread overview]
Message-ID: <20250905132328.9859-3-cn.liweihao@gmail.com> (raw)
In-Reply-To: <20250905132328.9859-1-cn.liweihao@gmail.com>
We need a clock id to assign clock parent when use i2s 8ch as audio
device, CLK_I2S_8CH_FRAC should be CLK_I2S_8CH_PRE parent so we can get
frequency we want.
