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

[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.

Hi,

this goes on top of Justin's A523/H728/T527 IR receiver series.

Cheers,
Andre
