Hi,
this is a second shot at adding support for the CODA960 Video
Processing Unit on i.MX6Q/D/DL/S SoCs to the coda driver.
Changes since v1:
- Dropped force IDR patch.
- Dropped enum_framesizes for now.
- Clear B frame flag for decoder I/P/B frame detection.
- Rewrote g_selection to only allow CROP target on OUTPUT and
COMPOSE target on CAPTURE buffers.
- Use pm_runtime_enabled()
This series contains a few fixes and preparations, the CODA960
support patch, a rework of the hardware access serialization
into a single threaded workqueue, some cleanups to use more
infrastructure that is available in the meantime, runtime PM
support, a few h.264 related v4l2 controls and fixes, support
for hard resets via the i.MX system reset controller, and a
patch that exports internal buffers to debugfs.
regards
Philipp
