Rename soc_camera to pxa_camera as this has no longer anything to do with the old soc_camera driver/framework. It's confusing when grepping on soc_camera. Signed-off-by:

On faster CPUs a delay is required after the resume command and the restart command. Without the delay, the restart command often returns -EREMOTEIO and the Si2168 does not restart. Note that this patch fixes the same issue as https://patchwork.linuxtv.org/patch/44304/, but I believe my udelay() fix addresses the actual problem. Signed-off-by:

While the failure handling in dvb_input_attach() has been improved lately so any tuner failure won't result in demod driver modules with a usecount > 0 anymore (thus requiring rmmod -f), there's still an issue with stv090x and stv0910 based tuner modules, in that LNB driver attach failures leave an attached demod frontend driver behind which have a usecount of > 0 in this failure case, due to them not being detached/ released. Fix this by detaching the demod frontends if the LNB driver fails. Richard tested and verified the changes with STV0910 hardware, thus adding his Tested-by. Signed-off-by:

With CONFIG_KASAN enabled, we get a relatively large stack frame in one function drivers/media/tuners/tda8290.c: In function 'tda8290_set_params': drivers/media/tuners/tda8290.c:310:1: warning: the frame size of 1520 bytes is larger than 1024 bytes [-Wframe-larger-than=] With CONFIG_KASAN_EXTRA this goes up to drivers/media/tuners/tda8290.c: In function 'tda8290_set_params': drivers/media/tuners/tda8290.c:310:1: error: the frame size of 3200 bytes is larger than 3072 bytes [-Werror=frame-larger-than=] We can significantly reduce this by marking local arrays as 'static const', and this should result in better compiled code for everyone.

CEC autorepeat is different than other protocols. Autorepeat is triggered by the first repeated user control pressed CEC message, rather than a fixed REP_DELAY. This change also does away with the KEY_UP event directly after the first KEY_DOWN event, which was used to stop autorepeat from starting. See commit a9a249a2 ("media: cec: fix remote control passthrough") for the original change. Acked-by:

This patch changes the 32-bit time type (timeval) to the 64-bit one (ktime_t), since 32-bit time types will break in the year 2038. I use ktime_t instead of all uses of timeval in imon.c This patch also changes do_gettimeofday() to ktime_get() accordingly, since ktime_get returns a ktime_t, but do_gettimeofday returns a struct timeval, and the other reason is that ktime_get() uses the monotonic clock.

Once rc_unregister_device() has been called, no driver function should be called. This prevents some nasty race conditions with an ioctl calls driver functions when the driver specific data has been freed. Signed-off-by:

This makes it possible for lircd to read from a lirc chardev, and not keep it busy. Note that this changes the default for timeout reports to on. lircd already enables timeout reports when it opens a lirc device, leaving them on until the next reboot. Signed-off-by:

Since removing the lirc kapi, ir-lirc-codec.c only contains lirc fops so the file name is no longer correct. By moving its content into lirc_dev.c the ugly extern struct lirc_fops is not longer needed, and everything lirc related is in one file. Signed-off-by:

If you try to store u64 in a kfifo (or a struct with u64 members), then the buf member of __STRUCT_KFIFO_PTR will cause 4 bytes padding due to alignment (note that struct __kfifo is 20 bytes on 32 bit). That in turn causes the __is_kfifo_ptr() to fail, which is caught by kfifo_alloc(), which now returns EINVAL. So, ensure that __is_kfifo_ptr() compares to the right structure. Signed-off-by:

Now that the lirc interface supports scancodes, RC scancode devices can also have a lirc device. The only receiving feature they will have enabled is LIRC_CAN_REC_SCANCODE. Note that CEC devices have no lirc device, since they can be controlled from their /dev/cecN chardev. Signed-off-by:

This implements LIRC_MODE_SCANCODE reading from the lirc device. The scancode can be read from the input device too, but with this interface you get the rc protocol, keycode, toggle and repeat status in addition to just the scancode. int main() { int fd, mode, rc; fd = open("/dev/lirc0", O_RDWR); mode = LIRC_MODE_SCANCODE; if (ioctl(fd, LIRC_SET_REC_MODE, &mode)) { // kernel too old or lirc does not support transmit } struct lirc_scancode scancode; while (read(fd, &scancode, sizeof(scancode)) == sizeof(scancode)) { printf("protocol:%d scancode:0x%x toggle:%d repeat:%d\n", scancode.rc_proto, scancode.scancode, !!(scancode.flags & LIRC_SCANCODE_FLAG_TOGGLE), !!(scancode.flags & LIRC_SCANCODE_FLAG_REPEAT)); } close(fd); } Signed-off-by: -

rc-core has replaced the lirc kapi many years ago, and now with the last driver ported to rc-core, we can finally remove it. Note this has no effect on userspace. All future IR drivers should use the rc-core api. Signed-off-by:

If a lirc chardev is held open after a device is unplugged, rc_close() will be called after rc_unregister_device(). The driver is not expecting any calls at this point, and the iguanair driver causes an oops in this scenario. rc_open() can be called when the device is removed too, by calling open on the chardev whilst the device is being removed.

The lirc user interface exists as a raw decoder, which does not make much sense for transmit-only devices. In addition, we want to have lirc char devices for devices which do not use raw IR, i.e. scancode only devices. Note that rc-code, lirc_dev, ir-lirc-codec are now calling functions of each other, so they've been merged into one module rc-core to avoid circular dependencies. Since ir-lirc-codec no longer exists as separate codec module, there is no need for RC_DRIVER_IR_RAW_TX type drivers to call ir_raw_event_register(). Signed-off-by:

This introduces a new lirc mode: scancode. Any device which can send raw IR can now also send scancodes. int main() { int mode, fd = open("/dev/lirc0", O_RDWR); mode = LIRC_MODE_SCANCODE; if (ioctl(fd, LIRC_SET_SEND_MODE, &mode)) { // kernel too old or lirc does not support transmit } struct lirc_scancode scancode = { .scancode = 0x1e3d, .rc_proto = RC_PROTO_RC5, }; write(fd, &scancode, sizeof(scancode)); close(fd); } The other fields of lirc_scancode must be set to 0. Note that toggle (rc5, rc6) and repeats (nec) are not implemented. Nor is there a method for holding down a key for a period. Signed-off-by: -

The ir-kbd-i2c driver behaves like the lirc_zilog driver, except it can send raw IR and receives scancodes rather than lirccodes. The lirc_zilog driver only polls if the lirc chardev is opened; similarly the ir-kbd-i2c driver only polls if the corresponding input device is opened, or the lirc device. Polling is disabled during IR transmission through the mutex. The polling period is 402ms in the ir-kdb-i2c driver, and 260ms in the lirc_zilog driver. Signed-off-by:

This is a fix for commit 329d88da ("[media] media: i2c: Don't export ir-kbd-i2c module alias") that stopped the module from being loaded automagically. The problems described only affect the HD-PVR, so it should not affect other hardware; also if the module happens to be loaded, the i2c IR part of the HD-PVR will be enabled anyway.

This code implements the transmitter which is currently implemented in the staging lirc_zilog driver. The new code does not need a signal database, iow. the haup-ir-blaster.bin firmware file is no longer needed, and the driver does not know anything about the keycodes in that file. Instead, the new driver can send raw IR, but the hardware is limited to few different lengths of pulse and spaces, so it is best to use generated IR rather than recorded IR. Signed-off-by:
