From: Guoniu Zhou <redacted> The CSI-2 in the i.MX8ULP is almost identical to the version present in the i.MX8QXP/QM and is routed to the ISI. Add both the ISI and CSI nodes and mark them as disabled by default since capture is dependent on an attached camera. Signed-off-by: Guoniu Zhou <redacted> ---
suppose dts is last patch because binding and driver will be pickup by media maintainer first, then shawn pick up dts part. Reviewed-by: Frank Li <Frank.Li@nxp.com>
