Add support for the larger fifo found on sun5i and sun6i, having a separate compatible for the ir found on sun5i & sun6i also is useful if we ever want to add ir transmit support, because the sun5i & sun6i version do not have transmit support. Note this commits also adds checking for the end-of-packet interrupt flag (which was already enabled), as the fifo-data-available interrupt flag only gets set when the trigger-level is exceeded. So far we've been getting away with not doing this because of the low trigger-level, but this is something which we should have done since day one.

Device-Tree bindings for SUNXI IR controller found in sunXi SoC family
|
|
|
|
Required properties:
|
|
- compatible : "allwinner,sun4i-a10-ir" or "allwinner,sun5i-a13-ir"
|
|
- clocks : list of clock specifiers, corresponding to
|
|
entries in clock-names property;
|
|
- clock-names : should contain "apb" and "ir" entries;
|
|
- interrupts : should contain IR IRQ number;
|
|
- reg : should contain IO map address for IR.
|
|
|
|
Optional properties:
|
|
- linux,rc-map-name : Remote control map name.
|
|
- resets : phandle + reset specifier pair
|
|
|
|
Example:
|
|
|
|
ir0: ir@01c21800 {
|
|
compatible = "allwinner,sun4i-a10-ir";
|
|
clocks = <&apb0_gates 6>, <&ir0_clk>;
|
|
clock-names = "apb", "ir";
|
|
resets = <&apb0_rst 1>;
|
|
interrupts = <0 5 1>;
|
|
reg = <0x01C21800 0x40>;
|
|
linux,rc-map-name = "rc-rc6-mce";
|
|
};
