[PATCH v5 00/12] Improve the MT8365 SoC and EVK board support

[PATCH v5 00/12] Improve the MT8365 SoC and EVK board support

[Alexandre Mergnat]

This commits are based on the Fabien Parent <fparent@baylibre.com> work.

The purpose of this series is to add the following HWs / IPs support for
the mt8365-evk board:
- Watchdog
- Power Management Integrated Circuit "PMIC" wrapper
- MT6357 PMIC
- MultiMediaCard "MMC" & Secure Digital "SD" controller
- USB controller
- Ethernet MAC controller

Add CPU Freq & IDLE support for this board.

This series depends to anothers which add support for MT8365 EVK board
[1], add the MT8365 I2C support [2] (both are currently applied) and
finally the pinctrl binding cleanup [3].

=== Build:

To test this serie, cherry-pick patches from the dependent series ([1],[2],[3])
and the applied patches from this serie (documented in the "Changes" below).
Be carefull, the pinctrl serie [3] is rebased to linusw/linux-pinctrl,
cherry-pick will not be straightforward.
Finally, cherry-pick this serie.

You can also take my branch [4] which have all the needed patches
retrieved from the instructions above.

Use the arm64 defconfig to make the build.

Regards,
Alex

Thanks for providing the branch with the dependencies.  With that, I
tested basic build & boot on mt8365-evk, and things are working as
expected.

I also enabled `CONFIG_USB_ETH=y` to test with USB ethernet gadget, and
was able use NFSroot, so that's working well also.

There's no commit description. Please add one, saying why this is needed.

I know why, but there's people who don't.

Can't we set vmc as parent of vemc?

I don't find parent property for regulators. AFAIK, vin-supply is used in other DTS to do that but is it supported by fixed-regulator and gpio-regulator, which is not the case here.
Based on this, I don't think so, but I'm probably missing something.

Why? They don't take bindings or dts files. Those go thru the subsystem 
(watchdog (for bindings) or Mediatek sub-arch tree.

Second, if they did pick this up, they likely need the original mail 
sent to them, not a reply.
