Subject: [PATCH v2 15/15] arm64: dts: st: enable imx335/csi/dcmipp pipeline
on stm32mp257f-ev1
Enable the camera pipeline with a imx335 sensor connected to the
dcmipp via the csi interface.
Signed-off-by: Alain Volmat <alain.volmat@...s.st.com>
---
v2:
- correct regulators & camera node names
- removal of powerdown property within imx335 node
- removal of useless status property within imx335 node
- correct imx335 reset-gpio polarity
