Subject: [PATCH v2] arm64: dts: imx8mp: Align both CSI2 pixel clock
Date: Tue, 16 Apr 2024 16:19:10 +0200 [thread overview]
Message-ID: <20240416141914.9375-1-marex@denx.de> (raw)
Configure both CSI2 assigned-clock-rates the same way.
There does not seem to be any reason for keeping the
two CSI2 pixel clock set to different frequencies.
This also reduces first CSI2 clock from overdrive mode
frequency which is 500 MHz down below the regular mode
frequency of 400 MHz.
