Checkpatch wants to use 'help' instead of '---help---':

	WARNING: prefer 'help' over '---help---' for new help texts

Let's change it globally at the media subsystem, as otherwise people

Benjamin Valentin 02d32bdad3 media: rc: add driver for Xbox DVD Movie Playback Kit
The Xbox DVD Movie Playback Kit is a USB dongle with an IR remote for the
Original Xbox.

Historically it has been supported by the out-of-tree lirc_xbox driver,
but this one has fallen out of favour and was just dropped from popular
Kodi (formerly XBMC) distributions.

This driver is heavily based on the ati_remote driver where all the
boilerplate was taken from - I was mostly just removing code.

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

But my recent kernels ended up with all kinds of IR decoders

Sean Young a60d64b15c media: lirc: lirc interface should not be a raw decoder
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().

Andi Shyti fe052da492 [media] rc: add support for IR LEDs driven through SPI
The ir-spi is a simple device driver which supports the
connection between an IR LED and the MOSI line of an SPI device.

The driver, indeed, uses the SPI framework to stream the raw data
provided by userspace through an rc character device. The chardev
is handled by the LIRC framework and its functionality basically
provides:

 - write: the driver gets a pulse/space signal and translates it
   to a binary signal that will be streamed to the IR led through
   the SPI framework.
 - set frequency: sets the frequency whith which the data should
   be sent. This is handle with ioctl with the
   LIRC_SET_SEND_CARRIER flag (as per lirc documentation)
 - set duty cycle: this is also handled with ioctl with the
   LIRC_SET_SEND_DUTY_CYCLE flag. The driver handles duty cycles
   of 50%, 60%, 70%, 75%, 80% and 90%, calculated on 16bit data.

The character device is created under /dev/lircX name, where X is
and ID assigned by the LIRC framework.

Example of usage:

        fd = open("/dev/lirc0", O_RDWR);
        if (fd < 0)
                return -1;

        val = 608000;
        ret = ioctl(fd, LIRC_SET_SEND_CARRIER, &val);
        if (ret < 0)
                return -1;

	val = 60;
        ret = ioctl(fd, LIRC_SET_SEND_DUTY_CYCLE, &val);
        if (ret < 0)
                return -1;

        n = write(fd, buffer, BUF_LEN);
        if (n < 0 || n != BUF_LEN)
                ret = -1;

        close(fd);

Let's fix it with minimal changes to pass the dmtimer calls in

be tested to be working for each change:

1. Change the non-pwm dmtimer to use just hrtimer if possible

2. Change the pwm dmtimer to use Linux PWM API with the new
   drivers/pwm/pwm-omap-dmtimer.c and remove the direct calls
   to dmtimer functions

3. Parse configuration from device tree and drop the pdata

seen with e.g. Sony protocols).

This patch adds driver for sunxi IR controller.
It is based on Alexsey Shestacov's work based on the original driver
supplied by Allwinner.

James Hogan 1d184b0bc1 [media] media: rc: add raw decoder for Sharp protocol
Add a raw decoder for the Sharp protocol. It uses a pulse distance
modulation with a pulse of 320us and a bit period of 2ms for a logical 1
and 1ms for a logical 0. The first part of the message consists of a
5-bit address, an 8-bit command, and two other bits, followed by a 40ms
gap before the echo message which is an inverted version of the main
message except for the address bits.

Srinivas Kandagatla 80f93c7b0f [media] media: st-rc: Add ST remote control driver
This patch adds support to ST RC driver, which is basically a IR/UHF
receiver and transmitter. This IP (IRB) is common across all the ST
parts for settop box platforms. IRB is embedded in ST COMMS IP block.
It supports both Rx & Tx functionality.
This driver adds only Rx functionality via LIRC codec.

Sean Young 1ac7fdeeb5 [media] winbond: wire up rc feedback led
Note that with the rc-feedback trigger, the cir-rx trigger is now
redundant. The cir-tx trigger is not used by default; if this
functionality is desired then it should exist in rc-core, not in
a driver.
Also make sure that the led is suspended on suspend.

Arnd Bergmann e71918ea66 [media] ir: IR_RX51 only works on OMAP2
This driver can be enabled on OMAP1 at the moment, which breaks
allyesconfig for that platform. Let's mark it OMAP2PLUS-only
in Kconfig, since that is the only thing it builds on.

Tony Lindgren a62a6e98c3 ARM: OMAP2+: Disable code that currently does not work with multiplaform
We still need to fix up few places for multiplatform support,
but that can proceed separately. Fix the issue by making the
problem drivers depends !ARCH_MULTIPLATFORM for now.

The remaining pieces that are not multiplatform compatible
for omap2+ SoCs are:

1. Some drivers are using custom omap_dm_timer calls

There are two drivers that are directly usign omap hardware
timers for PWM and DSP clocking: drivers/media/rc/ir-rx51.c and
drivers/staging/tidspbridge/core/dsp-clock.c. These can be
fixed for multiplatform by allowing a minimal set of hardware
timers to be accessed, and for some functionality by using the
hrtimer framework.

2. Hardware OMAP4_ERRATA_I688 needs to be fixed up

This can't be enabled for multiplatform configurations in
it's current form. It may be possible to fix it up to do
instruction replacement early on during init. Luckily it
looks like this errata does not seem to get hit with
mainline kernel code alone at least currently.

3. Legacy header needed for omap-sham.c

Looks like it still needs mach/irqs.h for omap1 that
does not exist for multiplatform systems. Just ifdef
it for now.

4. Mailbox is waiting to get moved to drivers

Disable it for now to avoid adding a dependency to the
mailbox patches.

Timo Kokkonen 36aee5ff90 [media] ir-rx51: Adjust dependencies
Although this kind of IR diode circuitry is known to exist only in
N900 hardware, nothing prevents making similar circuitry on any OMAP
based board. The MACH_NOKIA_RX51 dependency is thus not something we
want to be there.

Also, this should depend on LIRC as it is a LIRC driver.
