[PATCH v1 0/3] arm64: dts: amlogic: meson-s4: enable RTC and IR for Khadas VIM1S
Posted by Nick Xie 6 days, 6 hours ago
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.

Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (v7.1/arm64-dt)

These changes has been applied on the intermediate git tree [1].

The v7.1/arm64-dt branch will then be sent via a formal Pull Request to the Linux SoC maintainers
for inclusion in their intermediate git branches in order to be sent to Linus during
the next merge window, or sooner if it's a set of fixes.

In the cases of fixes, those will be merged in the current release candidate
kernel and as soon they appear on the Linux master branch they will be
backported to the previous Stable and Long-Stable kernels [2].

The intermediate git branches are merged daily in the linux-next tree [3],
people are encouraged testing these pre-release kernels and report issues on the
relevant mailing-lists.

If problems are discovered on those changes, please submit a signed-off-by revert
patch followed by a corrective changeset.
