Subject: [PATCH V3 4/8] clk: qcom: videocc-sm8550: Add SM8650 video clock controller
Date: Tue, 30 Apr 2024 19:57:53 +0530 [thread overview]
Message-ID: <20240430142757.16872-5-quic_jkona@quicinc.com> (raw)
In-Reply-To: <20240430142757.16872-1-quic_jkona@quicinc.com>
Add support to the SM8650 video clock controller by extending
the SM8550 video clock controller, which is mostly identical
but SM8650 has few additional clocks and minor differences.
Signed-off-by: Jagadeesh Kona <quic_jkona@quicinc.com>
