Srinivas Kandagatla 89d7ce5a0f [media] media: st-rc: move to using reset_control_get_optional
This patch fixes a compilation error while building with the
random kernel configuration.

drivers/media/rc/st_rc.c: In function 'st_rc_probe':
drivers/media/rc/st_rc.c:281:2: error: implicit declaration of
function 'reset_control_get' [-Werror=implicit-function-declaration]
  rc_dev->rstc = reset_control_get(dev, NULL);

drivers/media/rc/st_rc.c:281:15: warning: assignment makes pointer
from integer without a cast [enabled by default]
  rc_dev->rstc = reset_control_get(dev, NULL);

David Härdeman c5540fbb9d [media] rc-core: remove protocol arrays
The basic API of rc-core used to be:

	dev = rc_allocate_device();
	dev->x = a;
	dev->y = b;
	dev->z = c;
	rc_register_device();

which is a pretty common pattern in the kernel, after the introduction of
protocol arrays the API looks something like:

	dev = rc_allocate_device();
	dev->x = a;
	rc_set_allowed_protocols(dev, RC_BIT_X);
	dev->z = c;
	rc_register_device();

There's no real need for the protocols to be an array, so change it
back to be consistent (and in preparation for the following patches).

James Hogan 1a1934fab0 [media] rc: abstract access to allowed/enabled protocols
The allowed and enabled protocol masks need to be expanded to be per
filter type in order to support wakeup filter protocol selection. To
ease that process abstract access to the rc_dev::allowed_protos and
rc_dev::enabled_protocols members with inline functions.

Srinivas Kandagatla 1d504b649f [media] media: st-rc: Add reset support
Some of the SOCs hold the IRB IP in softreset state by default.
For this IP to work driver needs to bring it out of softreset.
This patch adds support to reset the IP via reset framework.

Without this patch the driver can not work with SoCs which holds the IP
in softreset.

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.
