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

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

2018-05-30T10:38:40+00:00

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

2018-04-20T13:16:55+00:00

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

2018-04-20T13:15:18+00:00

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

2018-04-20T13:12:43+00:00

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

2018-02-27T13:15:32+00:00

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

2018-02-14T19:17:21+00:00

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

2018-02-14T19:16:39+00:00

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

media: rc: remove IR_dprintk() from rc-core

2018-02-14T19:15:46+00:00

Use dev_dbg() rather than custom debug function. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

vfs: do bulk POLL* -> EPOLL* replacement

2018-02-11T22:34:03+00:00

This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^$[^\"]*$$\$/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: Al Viro Signed-off-by: Linus Torvalds
