[PATCH v2 0/2] arm64: amlogic: Add initial support for BPI-M2S variants

[PATCH v2 0/2] arm64: amlogic: Add initial support for BPI-M2S variants

[Christian Hewitt]

Add support for the BananaPi M2S which ships in two board variants with
the Amlogic S922X or A311D chipset. Schematics for the board are not
currently available from Sinovoip so the device-tree is largely derived
from the Khadas VIM3 (also S922X/A311D) and other recent BPI boards that
have public documentation. The device-tree also supports the RTL8822CS
WiFi/BT module. This is optional so the nodes must be enabled though an
overlay or fdtput.

Patches are based on current (v6.3) for-next branch.

Changes from v1:
- Fix LED node names to follow schema
- Add Krzysztof's ack to bindings patch

[PATCH v2 2/2] arm64: dts: meson: add support for BananaPi M2S variants

[Christian Hewitt]

BananaPi M2S ships in Amlogic S922X and A311D variants with the
following common specifications:

- 16GB eMMC
- HDMI 2.1a video
- 2x 10/100/1000 Base-T Ethernet (1x RTL8211F, 1x RTL811H)
- 2x USB 2.0 ports
- 2x Status LED's (green/blue)
- 1x Power/Reset button
- 1x micro SD card slot
- 40-pin GPIO header
- PWM fan header
- UART header

The S992X variant has:
- 2GB LPDDR4 RAM

The A311D variant has:

- 4GB LPDDR4 RAM
- NPU (5.0 TOPS)
- MIPI DSI header
- MIPI CSI header

An optional RTL8822CS SDIO WiFi/BT mezzanine is available for
both board variants.

Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (v6.4/arm64-dt)

[1/2] dt-bindings: arm: amlogic: add support for BananaPi M2S variants
      https://git.kernel.org/amlogic/c/0e1598a112f2e270bdd5771bb821f12852c548ac

      https://git.kernel.org/amlogic/c/14e14723d2f58964f13e825738d01f62a8629e90

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

The v6.4/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.
