[media] lirc_dev: make fops mandatory

2017-06-06T12:02:20Z

Every caller of lirc_register_driver() passes their own fops and there are no users of lirc_dev_fop_write() in the kernel tree. Thus we can make fops mandatory and remove lirc_dev_fop_write(). Signed-off-by: David Härdeman Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

[media] lirc_dev: remove sampling kthread

[media] lirc_dev: remove unused set_use_inc/set_use_dec

2017-06-06T12:00:11Z

Since there are no users of this functionality, it can be removed altogether. Signed-off-by: David Härdeman Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

[media] doc-rst: Fix issues with RC documentation

2016-07-17T17:02:43Z

The kernel-doc script is now broken if it doesn't find all exported symbols documented. Signed-off-by: Mauro Carvalho Chehab

[media] lirc_dev.h: Make checkpatch happy

Remove warnings about bad whitespacing at function struct parameters. Signed-off-by: Mauro Carvalho Chehab

[media] DocBook: Convert struct lirc_driver to doc-nano format

2015-10-05T16:49:03Z

The struct lirc_driver is already documented, but on some internal format. Convert it to Kernel doc-nano format and add documentation for some additional parameters that are also present at the structure. Signed-off-by: Mauro Carvalho Chehab

[media] lirc: use kfifo_initialized() on lirc_buffer's fifo

2014-11-03T14:53:05Z

We can use kfifo_initialized() to check if the fifo in lirc_buffer is initialized or not. There's no need to have a dedicated fifo status variable in lirc_buffer.

[media] media: lirc: Allow lirc dev to talk to rc device

2013-07-31T19:30:27Z

The use case is simple, if any rc device has allowed protocols = RC_TYPE_LIRC and map_name = RC_MAP_LIRC set, the driver open will be never called. The reason for this is, all of the key maps except lirc have some KEYS in there map, so during rc_register_device process these keys are matched against the input drivers and open is performed, so for the case of RC_MAP_EMPTY, a vt/keyboard is matched and the driver open is performed. In case of lirc, there is no match and result is that there is no open performed, however the lirc-dev will go ahead and create a /dev/lirc0 node. Now when lircd/mode2 opens this device, no data is available because the driver was never opened. Other case pointed by Sean Young, As rc device gets opened via the input interface. If the input device is never opened (e.g. embedded with no console) then the rc open is never called and lirc will not work either. So that's another case. lirc_dev seems to have no link with actual rc device w.r.t open/close. This patch adds rc_dev pointer to lirc_driver structure for cases like this, so that it can do the open/close of the real driver in accordance to lircd/mode2 open/close. Without this patch its impossible to open a rc device which has RC_TYPE_LIRC ad RC_MAP_LIRC set. Signed-off-by: Srinivas Kandagatla Signed-off-by: Mauro Carvalho Chehab

[media] lirc_dev: store cdev in irctl, up maxdevs

2011-06-11T12:03:20Z

Store the cdev pointer in struct irctl, allocated dynamically as needed, rather than having a static array. At the same time, recycle some of the saved memory to nudge the maximum number of lirc devices supported up a ways -- its not that uncommon these days, now that we have the rc-core lirc bridge driver, to see a system with at least 4 raw IR receivers. (consider a mythtv backend with several video capture devices and the possible need for IR transmit hardware). Signed-off-by: Jarod Wilson Signed-off-by: Mauro Carvalho Chehab
