Add maintainer entry for the video multiplexer v4l2 subdevice driver that will control video bus multiplexers via the multiplexer framework. Signed-off-by:
-
Philipp Zabel authored
This driver can handle SoC internal and external video bus multiplexers, controlled by mux controllers provided by the mux controller framework, such as MMIO register bitfields or GPIOs. The subdevice passes through the mbus configuration of the active input to the output side. Since the mux framework is not yet merged, this driver contains temporary mmio-mux support to work without the framework. The driver should be converted to use the multiplexer API once the "mux: minimal mux subsystem" and "mux: mmio-based syscon mux controller" patches are merged. Signed-off-by:

This patch adds Digital Radio Interface (DRIF) support to R-Car Gen3 SoCs. The driver exposes each instance of DRIF as a V4L2 SDR device. A DRIF device represents a channel and each channel can have one or two sub-channels respectively depending on the target board. DRIF supports only Rx functionality. It receives samples from a RF frontend tuner chip it is interfaced with. The combination of DRIF and the tuner device, which is registered as a sub-device, determines the receive sample rate and format. In order to be compliant as a V4L2 SDR device, DRIF needs to bind with the tuner device, which can be provided by a third party vendor. DRIF acts as a slave device and the tuner device acts as a master transmitting the samples. The driver allows asynchronous binding of a tuner device that is registered as a v4l2 sub-device. The driver can learn about the tuner it is interfaced with based on port endpoint properties of the device in device tree. The V4L2 SDR device inherits the controls exposed by the tuner device. The device can also be configured to use either one or both of the data pins at runtime based on the master (tuner) configuration. Signed-off-by:

This patch adds documentation for the three new SDR formats V4L2_SDR_FMT_PCU16BE V4L2_SDR_FMT_PCU18BE V4L2_SDR_FMT_PCU20BE Signed-off-by:

Ramesh Shanmugasundaram authored
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:

Document the new CEC_CAP_NEEDS_HPD capability. 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:
