[PATCH v3 0/3] arm64: dts: meson-s4: add support for Khadas VIM1S

[Nick Xie <nick@khadas.com>]

This series adds initial support for the Khadas VIM1S single board computer.

The Khadas VIM1S is based on the Amlogic S905Y4 (S4 family) SoC.
It features:
 - 2GB LPDDR4 RAM
 - 16GB eMMC 5.1 storage
 - 32MB SPI flash
 - 100M Ethernet
 - AP6256 Wireless (802.11 a/b/g/n/ac, BT5.0)
 - HDMI 2.1 video
 - 2x USB 2.0 ports
 - 1x USB-C (power) with USB 2.0 OTG
 - 2x LED's (1x red, 1x white)
 - 3x buttons (power, function, reset)
 - IR receiver
 - 40pin GPIO Header
 - 1x micro SD card slot

Changes in v3:
- Split the patch series to properly distinguish between S805X2 and
  S905Y4 SoCs in dt-bindings and compatible strings.
- Patch 1: Updated bindings to use specific compatibles (s805x2/s905y4)
  instead of just generic s4.
- Patch 2: (New) Updated existing AQ222 dts to use the new s805x2 compatible.
- Patch 3: Updated compatible string to use s905y4.
- Fixed Author/SoB mismatch in all patches.
- Link to v2: https://lore.kernel.org/linux-amlogic/20260114062549.68954-1-nick@khadas.com/

Changes in v2:
- dts: fixed dtbs_check warning: removed unsupported 'enable-active-low' property
  from regulator-sd-3v3 node
- Link to v1: https://lore.kernel.org/linux-amlogic/20260113090951.35928-1-nick@khadas.com/
