[PATCH 0/2] ARM64: dts: Add support for Meson GXM

[Neil Armstrong]

The new Amlogic GXM SoC (S912) is part of the Meson GX family and is nearly
identical to GXM but with a second Quad-A53 core cluster.

The GXM dtsi includes the GXL dtsi and the p20x dtsi is refactored in a
common p20x/q20x to support the GXM Q200 and Q201 board that uses the exact
same board layout since the S905D and S912 are pinout compatible.

The last patch adds support for the Nexbox A1 Set-Top-Box based on the S912.

Changes since RFC :
 - Refactor the p20x/q20x dtsi into a single common file
 - Add support for Nexbox A1

Neil Armstrong (2):
  ARM64: dts: Add support for Meson GXM
  Add support for the Nexbox A1 board based on the Amlogic S912 SoC.

[PATCH 1/2] ARM64: dts: Add support for Meson GXM

[Neil Armstrong]

Following the Amlogic Linux kernel, it seem the only differences
between the GXL and GXM SoCs are the CPU Clusters.

This commit renames the gxl-s905d-p23x DTSI in a common file for
S905D p20x and S912 q20x boards.

Then adds a meson-gxm dtsi and reproduce the P23x to Q20x boards
dts files since the S905D and S912 SoCs shares the same pinout
and the P23x and Q20x boards are identical.

Applied.

Git tip: for future reference, set 'git config diff.renames true' so and
the diffstat shows a better summary when files are moved/renamed.

e.g, rather than the large ++ and -- above, you'd see:

 ...gxl-s905d-p23x.dtsi => meson-gx-p23x-q20x.dtsi} |   4 +-
 
Which is much more comforting to a maintainer than a bunch of
(potentially unrelated) adds and removes.

Thanks,

Kevin

I had to drop this as it breaks the network on (at least) gxbb-p200, but...

... backing out this change makes it work again.

This change also looks suspicious as it's using the proposed disable-eee
properties, which I don't think have been merged yet.

This also doesn't look releveant to the GXL/GXM changes being introduced
in this patch.

Could you separate out any GXBB-related changes into a separate patch
(if they are in fact needed) and re-spin this?

Thanks,

Kevin
