[PATCH v1 0/3] arm64: dts: amlogic: meson-s4: enable RTC and IR for Khadas VIM1S
From: Nick Xie
Date: Fri Mar 27 2026 - 05:37:08 EST
This series adds support for the Real Time Clock (RTC) on the Amlogic
Meson S4 (S905Y4) SoC and enables the hardware RTC and IR receiver on
the Khadas VIM1S board.
- Patch 1 adds the internal Virtual RTC (VRTC) controller node to the
Meson S4 SoC dtsi.
- Patch 2 enables the I2C-attached Haoyu Micro HYM8563 RTC on the
Khadas VIM1S board. It also sets up aliases to ensure the hardware
RTC is prioritized as rtc0 over the VRTC.
- Patch 3 configures the default keymap to "rc-khadas" to support the
official Khadas IR remote control.
