This is an automatic generated email to let you know that the following patch were queued: Subject: media: cedrus: Program output format during each run Author: Samuel Holland <samuel@sholland.org> Date: Sat May 9 22:06:42 2020 +0200 Previously, the output format was programmed as part of the ioctl() handler. However, this has two problems: 1) If there are multiple active streams with different output formats, the hardware will use whichever format was set last for both streams. Similarly, an ioctl() done in an inactive context will wrongly affect other active contexts. 2) The registers are written while the device is not actively streaming. To enable runtime PM tied to the streaming state, all hardware access needs to be moved inside cedrus_device_run(). The call to cedrus_dst_format_set() is now placed just before the codec-specific callback that programs the hardware.
