This patch series depends on Jian's SCMI clock patches yet to merge
https://lore.kernel.org/all/20260313070022.700437-1-jian.hu@amlogic.com/

This series adds device tree support for the MMC, SD card and SDIO
interfaces on the Amlogic T7 SoC and the Khadas VIM4 board.

The first patches add the necessary building blocks in the T7 SoC
DTSI: pinctrl nodes for pin muxing, PWM controller nodes, and MMC
controller nodes. The amlogic,t7-mmc and amlogic,t7-pwm compatible
strings are introduced with fallbacks to existing drivers, avoiding
the need for new driver code.

The remaining patches enable these interfaces on the Khadas VIM4
board, including the power regulators, the SDIO power sequence and
32.768kHz PWM clock required by the BCM43752 Wi-Fi module, and the
board-specific MMC controller configurations.

Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (v7.1/arm64-dt)

[1/9] arm64: dts: amlogic: t7: Add eMMC, SD card and SDIO pinctrl nodes
      https://git.kernel.org/amlogic/c/fb69fa2cabc68da247bcc0bc99a14dc857b16842
[4/9] arm64: dts: amlogic: t7: Add PWM pinctrl nodes
      https://git.kernel.org/amlogic/c/b1e49f6c1ac15b2c947bdb1d22a82b823de22d27
[6/9] arm64: dts: amlogic: t7: khadas-vim4: Add power regulators
      https://git.kernel.org/amlogic/c/60eff75ac67bbf5445bdbd2842b0109ac591441c

These changes has been applied on the intermediate git tree [1].

The v7.1/arm64-dt branch will then be sent via a formal Pull Request to the Linux SoC maintainers
for inclusion in their intermediate git branches in order to be sent to Linus during
the next merge window, or sooner if it's a set of fixes.

In the cases of fixes, those will be merged in the current release candidate
kernel and as soon they appear on the Linux master branch they will be
backported to the previous Stable and Long-Stable kernels [2].

The intermediate git branches are merged daily in the linux-next tree [3],
people are encouraged testing these pre-release kernels and report issues on the
relevant mailing-lists.

If problems are discovered on those changes, please submit a signed-off-by revert
patch followed by a corrective changeset.

I'll pick patch 3,5,7 & 9 once patches 1 & 2 from [1] are merged.
