Previously, the code would loop for each of the 40 bits. Now it will branch for each edge in the IR, which will be much less. Signed-off-by:

The xbox dvd remote sends 24 bits, the first 12 bits are repeated and inverted so only 12 bits are used. The upper 4 bits can be read at offset 3. Ensure we pass this to rc-core and update the keymap accordingly. Tested-by:

The Xbox DVD Movie Playback Kit is a USB dongle with an IR remote for the Original Xbox. Historically it has been supported by the out-of-tree lirc_xbox driver, but this one has fallen out of favour and was just dropped from popular Kodi (formerly XBMC) distributions. This driver is heavily based on the ati_remote driver where all the boilerplate was taken from - I was mostly just removing code. Signed-off-by:

The three following Hauppauge USB DVB devices have IR receivers, but lacked the support in mceusb to enable it: - WinTV-HVR-935C - WinTV-HVR-955Q - WinTV-HVR-975 Tested HVR-955Q and HVR-975 plus RC5 remote and irw, works as intended. Signed-off-by:

Introduce support for Consumer-IR into seco-cec driver, as it shares the same interrupt for receiving messages. The device decodes RC5 signals only, defaults to hauppauge mapping. It will spawn an input interface using the RC framework (like CEC device). Signed-off-by:

This patch adds support to the CEC device implemented with a STM32 microcontroller in X86 SECO Boards, including UDOO X86. The communication is achieved via Braswell integrated SMBus (i2c-i801). The driver use direct access to the PCI addresses, due to the limitations of the specific driver in presence of ACPI calls. The basic functionalities are tested with success with cec-ctl and cec-compliance. Inspired by cros-ec-cec implementation, attaches to i915 driver cec-notifier. Signed-off-by:

Replace g/s_crop by g/s_selection and set the V4L2_FL_QUIRK_INVERTED_CROP flag since this is one of the old drivers that predates the selection API. Those old drivers allowed g_crop when it really shouldn't have since g_crop returns a compose rectangle instead of a crop rectangle for the CAPTURE stream, and vice versa for the OUTPUT stream. Also drop the now unused vidioc_cropcap. Signed-off-by:

Hans Verkuil authored
If g_selection is implemented, then the v4l2-ioctl cropcap code assumes that cropcap just implements the pixelaspect part and that g_selection provides the crop bounds and default rectangles. There are still some drivers that only implement cropcap and not g_selection. Split up cropcap into a cropcap and g_selection for those drivers. Signed-off-by:

Some old Samsung drivers use the legacy crop API incorrectly: the crop and compose targets are swapped. Normally VIDIOC_G_CROP will return the CROP rectangle of a CAPTURE stream and the COMPOSE rectangle of an OUTPUT stream. The Samsung drivers do the opposite. Note that these drivers predate the selection API. If this 'QUIRK' flag is set, then the v4l2-ioctl core will swap the CROP and COMPOSE targets as well. That way backwards compatibility is ensured and we can convert the Samsung drivers to the selection API. Signed-off-by:

While there are issues related to object lifetime management, unregister the media device first, followed immediately by other device nodes when the driver is being unbound. Only then the resources needed by the driver may be released. This is slightly safer. Signed-off-by:

Patch ad608fbc changed how events were subscribed to address an issue elsewhere. As a side effect of that change, the "add" callback was called before the event subscription was added to the list of subscribed events, causing the first event queued by the add callback (and possibly other events arriving soon afterwards) to be lost. Fix this by adding the subscription to the list before calling the "add" callback, and clean up afterwards if that fails.

During the configuration phase of a CEC adapter it is trying to claim a free logical address by polling. However, the code doesn't check if there were errors other than OK or NACK, those are just treated as if the poll was NACKed. Instead check for such errors and retry the poll. And if the problem persists then don't claim this LA since there is something weird going on. Signed-off-by:

We get a headers_check warning about the newly defined ioctl command structures: ./usr/include/linux/v4l2-controls.h:1105: found __[us]{8,16,32,64} type without #include <linux/types.h> This is resolved by including linux/types.h, as suggested by the warning, but there is another problem: Three of the four structures have an odd number of __u8 headers, but are aligned to 32 bit in the v4l2_ctrl_mpeg2_slice_params, so we get an implicit padding byte for each one. To solve that, let's add explicit padding that can be set to zero and verified in the kernel.
