[PATCH v6 00/12] Improve the MT8365 SoC and EVK board support

[PATCH v6 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

[PATCH v6 07/12] arm64: dts: mediatek: set vmc regulator as always on

[amergnat]

From: Fabien Parent <fparent@baylibre.com>

On downstream, we observe that the MSDC IP (used by the emmc, the micro
SD card and the WiFi) isn't working properly if the VMC regulator is
shutdown.

Make sure it is always on.
