This patch adds support for the three new SDR formats. These formats were prefixed with "planar" indicating I & Q data are not interleaved as in other formats. Here, I & Q data constitutes the top half and bottom half of the received buffer respectively. V4L2_SDR_FMT_PCU16BE - 14-bit complex (I & Q) unsigned big-endian sample inside 16-bit. V4L2 FourCC: PC16 V4L2_SDR_FMT_PCU18BE - 16-bit complex (I & Q) unsigned big-endian sample inside 18-bit. V4L2 FourCC: PC18 V4L2_SDR_FMT_PCU20BE - 18-bit complex (I & Q) unsigned big-endian sample inside 20-bit. V4L2 FourCC: PC20 Signed-off-by:

This patch adds driver support for the MAX2175 chip. This is Maxim Integrated's RF to Bits tuner front end chip designed for software-defined radio solutions. This driver exposes the tuner as a sub-device instance with standard and custom controls to configure the device. Signed-off-by:

-
Hans Verkuil authored
Add a new capability CEC_CAP_NEEDS_HPD. If this capability is set then the hardware can only use CEC if the HDMI Hotplug Detect pin is high. Such hardware cannot handle the corner case in the CEC specification where it is possible to transmit messages even if no hotplug signal is present (needed for some displays that turn off the HPD when in standby, but still have CEC enabled). Typically hardware that needs this capability have the HPD wired to the CEC block, often to a 'power' or 'active' pin. Signed-off-by:

Hans Verkuil authored
A simpler variant of cec_transmit_done to be used where the HW does just a single attempt at a transmit. So if the status indicates an error, then the corresponding error count will always be 1 and this function figures that out based on the status argument. Signed-off-by:

Use colorspace provided by the user as we are only doing scaling and color encoding conversion, we won't be able to transform the colorspace itself and the colorspace won't mater in that operation. Also always use output colorspace on the capture side. If the user does not provide a colorspace do not make it up, we might later while processing need to figure out the colorspace, which is possible depending on the frame size but do not ever guess and leak that guess to the userspace.

v4l2_m2m_job_finish(), which is called from the interrupt handler with slock acquired, can call the device_run() hook immediately if another context was in the queue. This hook also acquires slock, resulting in a deadlock for this scenario. Fix this by releasing slock right before calling v4l2_m2m_job_finish(). This is safe to do as the state of the hardware cannot change before v4l2_m2m_job_finish() is called anyway. Signed-off-by:

Now that rc_register_device() is reorganised, the dev->initialized hack can be removed. Any driver which calls rc_register_device() must be prepared for the device to go live immediately. The dev->initialized commits that are relevant are commit c73bbaa4 ("[media] rc-core: don't lock device at rc_register_device()") and commit 08aeb7c9 ("[media] rc: add locking to fix register/show race"). The original problem was that show_protocols() would access dev->rc_map.* and various other bits which are now properly initialized before device_add() is called. At the same time, remove the bogus "device is being removed" check. Signed-off-by:

The device core infrastructure is based on the presumption that once a driver calls device_add(), it must be ready to accept userspace interaction. This requires splitting rc_setup_rx_device() into two functions and reorganizing rc_register_device() so that as much work as possible is performed before calling device_add(). Signed-off-by:

Return NULL, if a null entity is parsed for it's v4l2_subdev Currently, the callers of media_entity_to_v4l2_subdev() need to make sure that the subdev is non-NULL, for example, when it is obtained from media_entity_remote_pad(). As this is a recurring pattern, add the check at the macro in order to avoid additional checks at the callers. Signed-off-by:

hmm_init calls hmm_alloc to set dummy_ptr, hmm_alloc calls hmm_init when dummy_ptr is not yet set, which is the case in the call from hmm_init, so it calls hmm_init again, this continues until we have a stack overflow due to the recursion. This commit fixes this by adding a separate flag for tracking if hmm_init has been called. Not pretty, but it gets the job done, eventually we should be able to remove the hmm_init call from hmm_alloc. Signed-off-by:
