The last scancode of a longer button press is decodes 64ms after the last-but-one which indicates the decoder doesn't use a timeout but decodes on the last edge of the signal. 267.042629: lirc protocol(unknown): scancode = 0xace 267.042665: event type EV_MSC(0x04): scancode = 0xace 267.042665: event type EV_KEY(0x01) key_down: KEY_1(0x0002) 267.042665: event type EV_SYN(0x00). 267.106625: lirc protocol(unknown): scancode = 0xace 267.106643: event type EV_MSC(0x04): scancode = 0xace 267.106643: event type EV_SYN(0x00). 267.170623: lirc protocol(unknown): scancode = 0xace 267.170638: event type EV_MSC(0x04): scancode = 0xace 267.170638: event type EV_SYN(0x00). 267.234621: lirc protocol(unknown): scancode = 0xace 267.234636: event type EV_MSC(0x04): scancode = 0xace 267.234636: event type EV_SYN(0x00). 267.298623: lirc protocol(unknown): scancode = 0xace 267.298638: event type EV_MSC(0x04): scancode = 0xace 267.298638: event type EV_SYN(0x00). 267.543345: event type EV_KEY(0x01) key_down: KEY_1(0x0002) 267.543345: event type EV_SYN(0x00). 267.570015: event type EV_KEY(0x01) key_up: KEY_1(0x0002) 267.570015: event type EV_SYN(0x00).

Media Device Allocator API to allows multiple drivers share a media device. This API solves a very common use-case for media devices where one physical device (an USB stick) provides both audio and video. When such media device exposes a standard USB Audio class, a proprietary Video class, two or more independent drivers will share a single physical USB bridge. In such cases, it is necessary to coordinate access to the shared resource. Using this API, drivers can allocate a media device with the shared struct device as the key. Once the media device is allocated by a driver, other drivers can get a reference to it. The media device is released when all the references are released. Signed-off-by:

If requests are used when they shouldn't, or not used when they should, then return EBADR (Invalid request descriptor) instead of EACCES. The reason for this change is that EACCES has more to do with permissions (not being the owner of the resource), but in this case the request file descriptor is just wrong for the current mode of the device. Update the documentation accordingly. Signed-off-by:

Stateless codecs require the use of the Request API as opposed of it being optional. So add a bit to indicate this and let vb2 check for this. If an attempt is made to queue a buffer without an associated request, then the EBADR error is returned to userspace. Doing this check in the vb2 core simplifies drivers, since they don't have to check for this, they can just set this flag. Signed-off-by:

The extended-controls.rst file had become too big. Split it up: each control class reference gets its own rst file, and this file just describes the Extended Control API. Each control class reference is also moved up one level into the table of contents to make it easier to find e.g. the codec control reference. Finally I rearranged the order so that all camera-related control classes are grouped together, ditto for codec/jpeg and fm-rx/tx. The ext-ctrls-codec.rst is still pretty big and it is a candidate to split up further in the future, possibly per codec. Signed-off-by:

The formats added in this patch include: V4L2_PIX_FMT_AYUV32 V4L2_PIX_FMT_XYUV32 V4L2_PIX_FMT_VUYA32 V4L2_PIX_FMT_VUYX32 These formats enable the trasmission of alpha channel data to other drivers and userspace applications in addition to YUV data. For example, buffers generated by drivers in one of these formats can be used by the Weston compositor to display as a texture or flipped directly onto the overlay planes with the help of a DRM driver.

However, by a wrong cut-and-paste, I ended by applying a GPL 2+ license text to it, while still using the GPL 2.0 SPDX tag, with would cause an ambiguity about the licensing model.
