Subject: [PATCH v2 4/4] arm64: dts: qcom: nord: Fix videocc clock inputs
Date: Thu,  8 Oct 2026 16:10:36 +0800	[thread overview]
Message-ID: <20261008081036.3492003-5-shengchao.guo@oss.qualcomm.com> (raw)
In-Reply-To: <20261008081036.3492003-1-shengchao.guo@oss.qualcomm.com>

The video clock controller binding describes three clock inputs for
Nord: the board XO, the always-on board XO and the 32 kHz sleep clock.
The videocc node instead passes the board XO and NW_GCC_VIDEO_AHB_CLK,
which is not an input of the controller.

Pass bi_tcxo_ao_div2 and the board sleep clock in place of the AHB
clock. No functional change, NW_GCC_VIDEO_AHB_CLK is kept always on by
the NW GCC driver.
