2021-02-06media: i2c: rdacm20: Constify static structsRikard Falkeborn
The only usage of rdacm20_video_ops is to assign it to the video field in the v4l2_subdev_ops struct which is a pointer to const, and the only usage of rdacm20_subdev_ops is to pass its address to v4l2_i2c_subdev_init() which accepts a pointer to const. Make them const to allow the compiler to put them in read-only memory.

2020-12-02media: rdacm20: Enable GPIO1 explicitlyJacopo Mondi
The MAX9271 GPIO1 line that controls the sensor reset is by default enabled after a serializer chip reset. As rdacm20 does not go through an explicit serializer reset, make sure GPIO1 is enabled to make the camera module driver more robust.

2020-07-19media: i2c: Add RDACM20 driverJacopo Mondi
The RDACM20 is a GMSL camera supporting 1280x800 resolution images developed by IMI based on an Omnivision 10635 sensor and a Maxim MAX9271 GMSL serializer. The GMSL link carries power, control (I2C) and video data over a single coax cable.
