2017-03-24[media] st_rc: simplify optional reset handlingPhilipp Zabel1-7/+6
As of commit bb475230b8e5 ("reset: make optional functions really optional"), the reset framework API calls use NULL pointers to describe optional, non-present reset controls. This allows to return errors from reset_control_get_optional and to call reset_control_(de)assert unconditionally.

2017-03-24[media] rc: lirc keymap no longer makes any senseSean Young1-1/+1
The lirc keymap existed once upon a time to select the lirc protocol. Since '275ddb4 [media] rc-core: remove the LIRC "protocol"', IR is always passed to the lirc decoder so this keymap is no longer needed.

2017-01-30[media] rc-main: assign driver type during allocationAndi Shyti1-2/+1
The driver type can be assigned immediately when an RC device requests to the framework to allocate the device. This is an 'enum rc_driver_type' data type and specifies whether the device is a raw receiver or scancode receiver. The type will be given as parameter to the rc_allocate_device device. Change accordingly all the drivers calling rc_allocate_device() so that the device type is specified during the rc device allocation. Whenever the device type is not specified, it will be set as RC_DRIVER_SCANCODE which was the default '0' value.

2017-01-30[media] rc: raw IR drivers cannot handle cec, unknown or otherSean Young1-1/+1
unknown and other are for IR protocols for which we have no decoder, so the raw IR drivers have no chance of generating them. cec is not an IR protocol.

2015-11-19[media] media: st-rc: remove misuse of IRQF_NO_SUSPEND flagSudeep Holla1-5/+9
The device is set as wakeup capable using proper wakeup API but the driver misuses IRQF_NO_SUSPEND to set the interrupt as wakeup source which is incorrect. This patch removes the use of IRQF_NO_SUSPEND flags replacing it with enable_irq_wake instead.

2014-07-25[media] rc-core: remove protocol arraysDavid Härdeman1-1/+1
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).

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.

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.
