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(). Signed-off-by:

Change get_frontend to re-check current lock status rather than relying on a cached value from get_status. Removes potential for tuning failure if get_frontend is called during tuning. Probably not too essential as other changes work around this: https://patchwork.linuxtv.org/patch/32845/Signed-off-by:

When CONFIG_MEDIA_CONTROLLER is disabled, we get a warning about an unused function: drivers/media/pci/saa7134/saa7134-core.c:832:13: error: 'saa7134_create_entities' defined but not used [-Werror=unused-function] This moves the #ifdef outside of the function, as it is never called here.

The cleanup that changed the em28xx driver to use v4l2_mc_create_media_graph instead of its own implementation causes a build error when CONFIG_MEDIA_CONTROLLER is disabled: drivers/media/usb/em28xx/em28xx-video.c: In function 'em28xx_v4l2_init': drivers/media/usb/em28xx/em28xx-video.c:2717:38: error: 'struct em28xx' has no member named 'media_dev' This puts the new code inside the same #ifdef that controls the presence of the 'media_dev' member, and that the old code was in.

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. [mchehab@osg.samsung.com: Fix merge conflicts] Signed-off-by:

Change vidioc_s_input() to enable the media source for the newly selected input. v4l2-core enables source before calling au0828's vidioc_s_input() handler. Hence, when input selection changes, media source for the newly selected input needs to be enabled. Signed-off-by: -

dev->ctrl_input is set in vidioc_s_input() and doesn't get set in au0828_s_input(). As a result, dev->ctrl_input is left uninitialized until user space calls s_input. It works correctly because the default input value is 0 and which is what dev->ctrl_input gets initialized via kzalloc(). Change to set dev->ctrl_input in au0828_s_input(). Also optimize vidioc_s_input() to return if the new input value is same as the current. Signed-off-by:

This patch adds a binary attribute /sys/class/rc/rc?/wakeup_data which allows to read / write the wakeup sequence. In combination with the core extension for exposing the most recent raw packet this allows to easily define and set a wakeup sequence. At least on my Zotac CI321 the BIOS resets the wakeup sequence at each boot to a factory default. Therefore I use a udev rule SUBSYSTEM=="rc", DRIVERS=="nuvoton-cir", ACTION=="add", RUN+="<script>" with the script basically doing cat <stored wakeup sequence> >/sys${DEVPATH}/wakeup_data Signed-off-by:Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by:
