media: lirc: lirc mode ioctls deal with current mode

2018-01-23T12:25:26Z

The ioctl change the current mode or return the current mode; they do not tell you which modes are possible (use the lirc features ioctl for that). Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: lirc: lirc daemon fails to detect raw IR device

2018-01-23T12:24:01Z

Since commit 9b6192589be7 ("media: lirc: implement scancode sending"), and commit de142c324106 ("media: lirc: implement reading scancode") the lirc features ioctl for raw IR devices advertises two modes for sending and receiving. The lirc daemon now fails to detect a raw IR device, both for transmit and receive. To fix this, do not advertise the scancode mode in the lirc features for raw IR devices (however do keep it for scancode devices). The mode can still be used via the LIRC_SET_{REC,SEND}_MODE ioctl.

media: lirc: when transmitting scancodes, block until transmit is done

2017-12-18T20:19:57Z

The semantics for lirc IR transmit with raw IR is that the write call should block until the IR is transmitted. Some drivers have no idea when this actually is (e.g. mceusb), so there is a wait. This is useful for userspace, as it might want to send a IR button press, a gap of a predefined number of milliseconds, and then send a repeat message. It turns out that for transmitting scancodes this feature is even more useful, as user space has no idea how long the IR is. So, maintain the existing semantics for IR scancode transmit.

media: RC docs: add enum rc_proto description at the docs

This is part of the uAPI. Add it to the documentation again, and fix cross-references. Signed-off-by: Mauro Carvalho Chehab Acked-by: Sean Young

media: lirc: remove name from lirc_dev

2017-12-14T15:35:20Z

This is a duplicate of rcdev->driver_name. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: lirc: remove LIRCCODE and LIRC_GET_LENGTH

2017-12-14T15:35:14Z

LIRCCODE is a lirc mode where a driver produces driver-dependent codes for receive and transmit. No driver uses this any more. The LIRC_GET_LENGTH ioctl was used for this mode only. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: docs: don't show ToC for each part on PDF output

2017-09-05T10:27:50Z

The "Table of Contents" of a PDF file is generated only once, at the beginning fo the output. It doesn't produce it on each part. So, don't output this text on each part of the document. Signed-off-by: Mauro Carvalho Chehab

media: rc-sysfs-nodes.rst: better use literals

2017-09-05T10:26:51Z

A literal box provides a better visual when pdf and html output is generated for things like the output of a sysfs devnode. It alsod matches other conventions used within the media book. So, use it. While here, use literals for protocol names. Signed-off-by: Mauro Carvalho Chehab
