[PATCH v3 0/4] media: rc: sunxi-cir: support the A523/H728/T527 IR receiver

[Justin Suess]

Hi,

Quick series respin for easier application.

This series adds support for the CIR receiver on the
Allwinner A523/T527/H728 family (sun55i).

One-line function name change s_cir -> s_cir_rx at Andre's
suggestion, with his patch for the Avaota A1 applied on top
for convenience.

[PATCH v3 1/4] media: dt-bindings: allwinner,sun4i-a10-ir: add A523 compatible

[Justin Suess]

The A523 (sun55i) contains a newer revision of the sunxi CIR receiver.
The reset defaults match the fixed behaviour of the older IP, so the
device works fine when driven as an A31 CIR receiver.

Add the A523 compatible, with allwinner,sun6i-a31-ir as the fallback.

While at it, merge the standalone compatible entries into a single
enum.

[PATCH v3 2/4] arm64: dts: allwinner: a523: add IR receiver nodes

[Justin Suess]

The A523 has two CIR receivers, both compatible with the A31 CIR: one
in the CPUX domain, clocked from the main CCU, and one in the RTC
power domain, clocked from the R-CCU.

Add nodes for both instances, disabled by default. Since the RX signal
of each instance can be routed to more than one pin, boards with an IR
receiver are expected to add the pinctrl properties next to where they
enable the node. Keep the PL11 pin description in the dtsi, as boards
commonly use that pin for the RTC domain instance.

[PATCH v3 3/4] arm64: dts: allwinner: a523: enable IR receiver on the X96Q Pro+

[Justin Suess]

The X96Q Pro+ TV box has an IR receiver window on the front panel,
wired to the SoC CIR input on PL11.

Enable the CIR receiver in the RTC power domain and mux its RX
signal to PL11.

Tested on an X96 Pro+ with ir-keytable and nec keybindings with
the remote that it came with in the box.

[PATCH v3 4/4] arm64: dts: allwinner: a523: enable IR on the Avaota A1

[Justin Suess]

From: Andre Przywara <andre.przywara@arm.com>

The Avaota A1 board has an IR receiver chip on the PCB (next to the
Ethernet jacks), wired to the PI8 pin on the SoC.

Add the pin description to the PIO DT node, and enable the CIR receiver
in the main power domain.

Tested on the board with evtest and some random TV remote control.
