[PATCH v2 0/3] arm64: dts: meson-g12a: mmc updates

[Neil Armstrong]

This patchset :
- adds the SDIO controller node using the dram-access-quirk
- adds SDCard, eMMC & SDIO support to X96
- Add SDIO support to SEI510

Changes since v1:
- removed already applied SDIO patch
- added missing clock input from pwm
- added reviewed-by tags

Guillaume La Roque (1):
  arm64: dts: meson-g12a-x96-max: add support for sdcard and emmc

Neil Armstrong (2):
  arm64: dts: meson-g12a-x96-max: Enable Wifi SDIO Module
  arm64: dts: meson-g12a-sei510: Enable Wifi SDIO module

[PATCH v2 2/3] arm64: dts: meson-g12a-x96-max: Enable Wifi SDIO Module

[Neil Armstrong]

The X96 Max embeds an AP6398S SDIO module, let's add the
corresponding SDIO, PWM clock and mmc-pwrseq nodes.
