2019-08-07media: vicodec: add support for 4 new RGB32 pixelformatsHans Verkuil

2019-08-05media: venus: make decoder compliant with stateful codec APIStanimir Varbanov
This refactors code for start/stop streaming vb2 operations and adds a state machine handling similar to the one in stateful codec API documentation. One major change is that now the HFI session is started on STREAMON(OUTPUT) and stopped on REQBUF(OUTPUT,count=0), during that time STREAMOFF(CAP,OUT) just flush buffers but doesn't stop the session. The other major change is that now the capture and output queues are completely separated.

2019-08-05media: venus: vdec_ctrls: get real minimum buffers for captureStanimir Varbanov
Until now we returned num_output_bufs set during reqbuf but that could be wrong when we implement stateful Codec API. So get the minimum buffers for capture from HFI. This is supposed to be called after stream header parsing, i.e. after dequeue v4l2 event for change resolution.

2019-08-04media: don't drop front-end reference count for ->detachArnd Bergmann
A bugfix introduce a link failure in configurations without CONFIG_MODULES: In file included from drivers/media/usb/dvb-usb/pctv452e.c:20:0: drivers/media/usb/dvb-usb/pctv452e.c: In function 'pctv452e_frontend_attach': drivers/media/dvb-frontends/stb0899_drv.h:151:36: error: weak declaration of 'stb0899_attach' being applied to a already existing, static definition The problem is that the !IS_REACHABLE() declaration of stb0899_attach() is a 'static inline' definition that clashes with the weak definition. I further observed that the bugfix was only done for one of the five users of stb0899_attach(), the other four still have the problem. This reverts the bugfix and instead addresses the problem by not dropping the reference count when calling '->detach()', instead we call this function directly in dvb_frontend_put() before dropping the kref on the front-end. I first submitted this in early 2018, and after some discussion it was apparently discarded. While there is a long-term plan in place, that plan is obviously not nearing completion yet, and the current kernel is still broken unless this patch is applied.

Rework OF endpoint parsing for the omap3isp driver. This does add some lines of code. The benefits are still clear: - the great complication related to callbacks in endpoint parsing is gone; instead endpoints are obtained port by port and - endpoints may now have a default bus configuration which was not possible while using callbacks.

2019-07-25media: v4l2-async: Get fwnode reference when putting it to the notifier's listSakari Ailus
The v4l2_async_notifier_add_fwnode_subdev() did not take a reference of the added fwnode, relying on the caller to handle that instead, in essence putting the fwnode to be added if there was an error. As the reference is eventually released during the notifier cleanup, this is not intuitive nor logical. Improve this by always getting a reference when the function succeeds, and the caller releasing the reference when it does not *itself* need it anymore. Luckily, perhaps, there were just a handful of callers using the function.
