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.

Device-Tree bindings for ST IRB IP
|
|
|
|
Required properties:
|
|
- compatible: Should contain "st,comms-irb".
|
|
- reg: Base physical address of the controller and length of memory
|
|
mapped region.
|
|
- interrupts: interrupt-specifier for the sole interrupt generated by
|
|
the device. The interrupt specifier format depends on the interrupt
|
|
controller parent.
|
|
- rx-mode: can be "infrared" or "uhf". This property specifies the L1
|
|
protocol used for receiving remote control signals. rx-mode should
|
|
be present iff the rx pins are wired up.
|
|
- tx-mode: should be "infrared". This property specifies the L1
|
|
protocol used for transmitting remote control signals. tx-mode should
|
|
be present iff the tx pins are wired up.
|
|
|
|
Optional properties:
|
|
- pinctrl-names, pinctrl-0: the pincontrol settings to configure muxing
|
|
properly for IRB pins.
|
|
- clocks : phandle with clock-specifier pair for IRB.
|
|
|
|
Example node:
|
|
|
|
rc: rc@fe518000 {
|
|
compatible = "st,comms-irb";
|
|
reg = <0xfe518000 0x234>;
|
|
interrupts = <0 203 0>;
|
|
rx-mode = "infrared";
|
|
};
