[PATCH v2 0/6] MT6795 Devicetrees and Sony Xperia M5

[PATCH v2 0/6] MT6795 Devicetrees and Sony Xperia M5

[AngeloGioacchino Del Regno]

This series brings some more support for the MT6795 SoC, as it
adds support for basic clock controllers (and resets) and all
of the mtk-sd mmc controllers.

While at it, since now it's possible to get the "first signs of
life" out of a MT6795 smartphone platform, add a basic devicetree
for the Sony Xperia M5 (codename "Holly") device as to start
preparing the ground for a gradual bringup.

This series depends on [1] my mt6795 clocks series.

P.S.: Thumbs up for the first MediaTek-powered ARM64 smartphone
      going upstream! :-) :-) :-)

Changes in v2:
 - Rebased over next-20221026
 - Removed "mediatek,mt8173-mmc" from mmc compatible strings
 - Added clock and reset dt-bindings headers inclusions

[PATCH v2 1/6] arm64: dts: mediatek: mt6795: Add topckgen, infra, peri clocks/resets

[AngeloGioacchino Del Regno]

Add nodes for topckgen, infracfg and pericfg, providing various
clocks and resets and needed to support basic IPs of this SoC.

[PATCH v2 2/6] arm64: dts: mediatek: mt6795: Replace UART dummy clocks with pericfg

[AngeloGioacchino Del Regno]

The UART nodes had a dummy clock for early bringup, as it is
expected that these are left on by the bootloader: now that
the pericfg clock controller is supported, we can replace
them with the real clocks.

[PATCH v2 4/6] arm64: dts: mediatek: mt6795: Add support for eMMC/SD/SDIO controllers

[AngeloGioacchino Del Regno]

Add the mmc nodes to support all of the four controllers, used for
eMMC, SD/MicroSD and SDIO storage.
All of these controller nodes are left disabled by default, as
usage is board dependent.
