Both formats have an alpha component so a new standard control is also added to control its value, V4L2_CID_ALPHA_COMPONENT. The series is based on the latest media-tree and is tested on both Renesas Gen2 and Gen3 hardware without any regressions found. Patch 1/4 fixes a badly named register name, 2/4 adds the new control while 3/4 adds the two new pixel formats. Patch 4/4 is a clean up now that Gen2 and Gen3 always have controls and v4l2_ctrl_handler_setup() should be called for both cases. * Changes since v2 - Protect the writing of the alpha value when streaming with the spin lock to make sure the streaming state is stable. - Add patch 4/4 to call v4l2_ctrl_handler_setup() for the media controller centric Gen3 mode of the driver.
