2.34.1
From: Yuntian Zhang <[email protected]>
Radxa Zero2 is a small form factor SBC based on the Amlogic A311D
chipset that ships in a number of eMMC configurations:
- Amlogic A311D (Quad A73 + Dual A53) CPU
- 4GB LPDDR4 RAM
- 32/64/128GB eMMC
- Mali G52-MP4 GPU
- HDMI 2.1 output (micro)
- BCM4345 WiFi (2.4/5GHz a/b/g/n/ac) and BT 5.0
- 1x USB 2.0 port - Type C (OTG)
- 1x USB 3.0 port - Type C (Host)
- 1x micro SD Card slot
- 40 Pin GPIO header

The original dts from Yuntian contains some additional content for
the USB-C device, but this is not working for me so I have ommited
it and kept things simple. I've also left out some pwm-fan/thermal
content; while the board does not ship with a fan the A311D chip
should be used with one and I believe the board has a connector to
add a fan, but until this is confirmed (and production boards are
available) it's best left out.
Changes from v1:
- Corrected underscores in node names
- Corrected wifi32k clock node name

Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (v6.3/arm64-dt)
[1/2] dt-bindings: arm: amlogic: add support for Radxa Zero2
https://git.kernel.org/amlogic/c/229cfc6b16ccedfcae1ee10dc1aed04e7a85ed32
[2/2] arm64: dts: meson: add support for Radxa Zero2
https://git.kernel.org/amlogic/c/d747e7f76a5fa6e3deb4c419df768f9ee49c2161
These changes has been applied on the intermediate git tree [1].
The v6.3/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.
