Since commit 363d0e56285e ("media: pwm-ir-tx: Trigger edges from
hrtimer interrupt context"), pwm-ir-tx uses high resolution timers
for IR signal generation when the pwm can be used from atomic context.
Ensure they are available.

The ir-rx51 is a pwm-based TX driver specific to the N900. This can be
handled entirely by the generic pwm-ir-tx driver, and in fact the
pwm-ir-tx driver has been compatible with ir-rx51 from the start.
Note that the suspend code in the ir-rx51 driver is unnecessary, since
during transmit, the process is not in interruptable sleep. The process
is not put to sleep until the transmit completes.

In a future patch HAS_IOPORT=n will result in inb()/outb() and friends

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.
It is actually better to always build such drivers with OF enabled,
so that the test builds are closer to how each driver will actually be
built on its intended target. Building them without OF may not test
much as the compiler will optimize out potentially large parts of the
code. In the worst case, this could even pop false positive warnings.
Dropping COMPILE_TEST here improves the quality of our testing and
avoids wasting time on non-existent issues.
As a minor optimization, this also lets us drop of_match_ptr(), as we
now know what it will resolve to, we might as well save cpp some work.

This driver is a port of the lirc_sir driver to rc-core. However, for
this driver I could not find any hardware to test, so it was done without
testing. This is a mistake.
There are clear bugs in the code. For example the two arguments
to ktime_us_delta() are reversed, which means the result is garbage.
The driver has been in the kernel for four years, and noone has ever
reported an issue. So, remove this driver.

The driver supports 2 modulation clock sources:
- xtal3 clock (xtal divided by 3)
- 1us clock

I came across a randconfig build failure from one driver
that only depends on CONFIG_USB_ARCH_HAS_HCD but fails when
built without CONFIG_USB:
ld: drivers/media/rc/ir_toy.o: in function `irtoy_disconnect':
ir_toy.c:(.text+0x24): undefined reference to `usb_kill_urb'
ld: ir_toy.c:(.text+0x2c): undefined reference to `usb_free_urb'
ld: ir_toy.c:(.text+0x34): undefined reference to `usb_kill_urb'
ld: ir_toy.c:(.text+0x3c): undefined reference to `usb_free_urb'
Upon a closer look, I find that a lot of the other drivers
'select USB' rather than stating 'depends on USB' as is common
for most subsystems. I also find that all except one driver
have an extra 'depends on RC_CORE' that is already implied by
the top-level 'if RC_CORE' check.
Clean up both by reducing the dependencies to the required set.

I usually update my config with make oldconfig and pressing return,
trusting that whoever updates Kconfig sets sensible defaults.
But my recent kernels ended up with all kinds of IR decoders
built in that are not used by anything because they are all
marked with default y.
default y should only be set for something that prevents
booting on common systems, never for some random weirdo
driver feature like this.

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().

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);

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
