Switch attribute wakeup_data from binary to a text attribute. This makes it easier to handle in userspace and allows to use the output of tools like mode2 almost as is to set a wakeup sequence. Changing to a text format and values in microseconds also makes the userspace interface independent of the setting of SAMPLE_PERIOD in the driver. In addition document the new sysfs attribute in Documentation/ABI/testing/sysfs-class-rc-nuvoton.

Add TODO files for mx2/mx3/omap1 to explain the status of these drivers and what needs to be done in order to keep them from being removed soon. Also a small fix for the mx2/Kconfig that mistakingly mentioned a vb2 conversion. That's not needed for that driver.

Start the audio defines with BASE + 0x03001 instead of 0x03000. This is consistent with the other defines, and I think it is good practice not to start with 0, just in case we want to do something like (id & 0xfff) in the future and treat the value 0 as a special case.

When snd_usb_audio gets probed first, audio mixer doesn't get linked to the decoder. Change au0828_media_graph_notify() to handle the mixer entity getting registered before the decoder.

Change ALSA driver to use Media Controller API to share media resources with DVB and V4L2 drivers on a AU0828 media device. Media Controller specific initialization is done after sound card is registered. ALSA creates Media interface and entity function graph nodes for Control, Mixer, PCM Playback, and PCM Capture devices. snd_usb_hw_params() will call Media Controller enable source handler interface to request the media resource. If resource request is granted, it will release it from snd_usb_hw_free(). If resource is busy, -EBUSY is returned. Media specific cleanup is done in usb_audio_disconnect().

This reverts commit 82c2ffeb ("[media] tvp5150: document input connectors DT bindings") since the DT binding is too device driver specific and should instead be more generic and use the bindings in Documentation/devicetree/bindings/display/connector/ and linked to the tvp5150 using the OF graph port and endpoints. There are still ongoing discussions about how the input connectors will be supported by the Media Controller framework so until that is settled, it is better to revert the connectors portion of the bindings to avoid known to be broken bindings docs to hit mainline.

When the Media controller framework was merged, it was decided not to add pipeline power management code for it was not seen generic. As a result, a number of drivers have copied the same piece of code, with same bugfixes done to them at different points of time (or not at all). Add these functions to V4L2. Their use is optional for drivers.
