[PATCH 1/2] dt-bindings: media: meson6-ir: Add Amlogic A9 IR compatible

[Xianwei Zhao via B4 Relay]

From: Xianwei Zhao <xianwei.zhao@amlogic.com>

Document the Amlogic A9 IR controller compatible string. The A9 IR
controller shares the same implementation as the Meson S4 IR block,
so add "amlogic,a9-ir" with "amlogic,meson-s4-ir" as the fallback
compatible.

[PATCH 2/2] arm64: dts: amlogic: a9: Add IR controller support

[Xianwei Zhao via B4 Relay]

From: Xianwei Zhao <xianwei.zhao@amlogic.com>

Add the IR controller node for the Amlogic A9 SoC and describe the
corresponding remote input pin configuration.

Enable the IR controller on the Amlogic A9 A311Y3 BY401 board with the
proper pinctrl setting.
