[PATCH 0/2] minor GXL and GXM improvements

[PATCH 0/2] minor GXL and GXM improvements

[Martin Blumenstingl]

This series adds SCPI support to GXL and GXM SoCs by moving the nodes
to meson-gx.dtsi. Additionally this updates the compatible string to
match the recent changes, see [0]

Now that we have SCPI support for GXM we can also use it to configure
the CPU cores using the SCPI DVFS clocks.

[PATCH 1/2] ARM64: dts: meson-gx: move the SCPI and SRAM nodes to meson-gx

[Martin Blumenstingl]

SCPI and SRAM are identical on GXBB and GXL. Moving the corresponding
nodes to meson-gx adds support for the thermal sensor on GXL based
devices.
While here, also rename the second compatible string because
"arm,legacy-scpi" was replaced by "arm,scpi-pre-1.0".

accordingly.

Can you rebase onto my current v4.10/dt64 branch please?  I have updated
the compatible string there.

[PATCH v2 0/2] GXL and GXM SCPI improvements

[Martin Blumenstingl]

This series adds SCPI support to GXL and GXM SoCs by moving the nodes
to meson-gx.dtsi.
Now that we have SCPI support for GXM we can also use it to configure
the CPU cores using the SCPI DVFS clocks.

Changes since v1:
- added Tested-By and Acked-By tags from Neil Armstrong (thanks!)
- rebased to khilman/linux-amlogic.git/amlogic-dt64-2-v2
- updated description of patch 1 because the "arm,scpi-pre-1.0" change
  is already part of the amlogic-dt64-2-v2 tag

[Martin Blumenstingl]

SCPI and SRAM are identical on GXBB and GXL. Moving the corresponding
nodes to meson-gx adds support for the thermal sensor on GXL based
devices.

[PATCH v2 1/2] ARM64: dts: meson-gx: move the SCPI and SRAM nodes to meson-gx

[Martin Blumenstingl]

SCPI and SRAM are identical on GXBB and GXL. Moving the corresponding
nodes to meson-gx adds support for the thermal sensor on GXL based
devices.

Thanks for the respin.  It's now too late for v4.10 (I freeze things
around -rc6 or -rc7, and it's now -rc8), but I'll queue this up for
v4.11.

Thanks,
