an S912 chip and the following specs:

- 3GB DDR3 RAM
- 32GB eMMC
- 10/100/1000 Base-T Ethernet
- AP6356 Wireless (802.11 b/g/n/ac, BT 5.0)
- HDMI 2.0a video
- VFD for clock/status
- 2x USB 2.0 ports
- IR receiver
- 1x Power LED (white)

Checkpatch generates the 'phy-mode "rgmii" without comment'
warning but this dts is using the same rgmii format as all
other Amlogic boards, so I have omitted a comment.

He’s the author of the original device tree that 95%
of the content for this one is taken from; as is the
case for most older Amlogic hardware. The decision
on which bits to copy and paste was all mine, but I’m
not  sure that skill deserves too much credit :)

I can resend with my own name (or mine appended) if
that would be preferred?

I just wasn't sure whether it was a left-over or on purpose.

I'll ultimately leave it up to Neil. Maybe if he wants your name in
too, he can just append it when applying?

So far we've been mimicking the vendor kernel (which sets up the MAC
to generate the delays and disables them on PHY level).
If we change it we should do so for all devices.

Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (v6.19/arm64-dt)

      https://git.kernel.org/amlogic/c/afd1e16c6d3f53810ea29b5269dfcfc233e9b6b9

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

The v6.19/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.
