media: lirc: drop trailing space from scancode transmit

2023-11-28T16:46:36Z

commit c8a489f820179fb12251e262b50303c29de991ac upstream. When transmitting, infrared drivers expect an odd number of samples; iow without a trailing space. No problems have been observed so far, so this is just belt and braces.

media: rc: IR signal for Panasonic air conditioner too long

2020-04-13T08:45:01Z

commit 5c4c8b4a999019f19e770cb55cbacb89c95897bd upstream. The IR signal to control the Panasonic ACXA75C00600 air conditioner has 439 pulse/spaces. Increase limit to make it possible to transmit signal. Reported-by: Takashi Kanamaru Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab Signed-off-by: Greg Kroah-Hartman

Merge tag 'media/v4.18-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

2018-06-07T19:34:37Z

Pull media updates from Mauro Carvalho Chehab: - remove of atomisp driver from staging, as nobody would have time to dedicate huge efforts to fix all the problems there. Also, we have a feeling that the driver may not even run the way it is. - move Zoran driver to staging, in order to be either fixed to use VB2 and the proper media kAPIs or to be removed - remove videobuf-dvb driver, with is unused for a while - some V4L2 documentation fixes/improvements - new sensor drivers: imx258 and ov7251 - a new driver was added to allow using I2C transparent drivers - several improvements at the ddbridge driver - several improvements at the ISDB pt1 driver, making it more coherent with the DVB framework - added a new platform driver for MIPI CSI-2 RX: cadence - now, all media drivers can be compiled on x86 with COMPILE_TEST - almost all media drivers now build on non-x86 architectures with COMPILE_TEST - lots of other random stuff: cleanups, support for new board models, bug fixes, etc * tag 'media/v4.18-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (464 commits) media: omap2: fix compile-testing with FB_OMAP2=m media: media/radio/Kconfig: add back RADIO_ISA media: v4l2-ioctl.c: fix missing unlock in __video_do_ioctl() media: pxa_camera: ignore -ENOIOCTLCMD from v4l2_subdev_call for s_power media: arch: sh: migor: Fix TW9910 PDN gpio media: staging: tegra-vde: Reset VDE regardless of memory client resetting failure media: marvel-ccic: mmp: select VIDEOBUF2_VMALLOC/DMA_CONTIG media: marvel-ccic: allow ccic and mmp drivers to coexist media: uvcvideo: Prevent setting unavailable flags media: ddbridge: conditionally enable fast TS for stv0910-equipped bridges media: dvb-frontends/stv0910: make TS speed configurable media: ddbridge/mci: add identifiers to function definition arguments media: ddbridge/mci: protect against out-of-bounds array access in stop() media: rc: ensure input/lirc device can be opened after register media: rc: nuvoton: Keep device enabled during reg init media: rc: nuvoton: Keep track of users on CIR enable/disable media: rc: nuvoton: Tweak the interrupt enabling dance media: uvcvideo: Support realtek's UVC 1.5 device media: uvcvideo: Fix driver reference counting media: gspca_zc3xx: Enable short exposure times for OV7648 ...

media: rc: introduce BPF_PROG_LIRC_MODE2

2018-05-30T10:38:40Z

Add support for BPF_PROG_LIRC_MODE2. This type of BPF program can call rc_keydown() to reported decoded IR scancodes, or rc_repeat() to report that the last key should be repeated. The bpf program can be attached to using the bpf(BPF_PROG_ATTACH) syscall; the target_fd must be the /dev/lircN device.

media: rc: per-protocol repeat period and minimum keyup timer

2018-04-20T13:16:55Z

Each IR protocol has its own repeat period. We can minimise the keyup timer to be the protocol period + IR timeout. This makes keys less "sticky" and makes IR more reactive and nicer to use. This feature was previously attempted in commit d57ea877af38 ("media: rc: per-protocol repeat period"), but that did not take the IR timeout into account, and had to be reverted.

media: rc: add ioctl to get the current timeout

2018-04-20T13:15:18Z

Since the kernel now modifies the timeout, make it possible to retrieve the current value. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: rc: report receiver and transmitter type on device register

2018-04-20T13:12:43Z

On the raspberry pi, we might have two lirc devices; one for sending and one for receiving. This change makes it much more apparent which one is which. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: rc: no need to announce major number

2018-02-27T13:15:32Z

Since commit a60d64b15c20 ("media: lirc: lirc interface should not be a raw decoder"), the message in the documentation is incorrect as the module name is rc_core, not lirc_dev. Since the message is not useful, just make the message debug and remove it from the documentation. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: rc: get start time just before calling driver tx

2018-02-14T19:17:21Z

The current code gets the start time before copying the IR from userspace (could cause page faults) and encoding IR. This means that the gap calculation could be off. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: rc: remove useless if statement

2018-02-14T19:16:39Z

ret is always 0, so remove if statement. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab
