[PATCH] arm64: dts: renesas: gray-hawk-single: Add video capture support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The Gray-Hawk single board contains two MAX96724 connected to the using
I2C and CSI-2, record the connections. Also enable all nodes (VIN, CSI-2
and ISP) that are part of the downstream video capture pipeline.

Hi Geert,

Part of this work was part of a series adding this as a separate DTSI
file. Per your suggestion this have been reworked to be directly
recorded in the single DTS file. If we ever add support for the multiple
board setup this can be reworked with the rest of things that would need
to be refactored.

All bindings and driver changes are already upstream and this is the
only missing piece to enable capture on V4M.
