Subject: [PATCH v2 0/8] Support SD/SDIO controllers on RK3528

RK3528 features two SDIO controllers and one SD/MMC controller. This
series adds essential support for their tuning clocks, document the
controller in dt-bindings and bring the SD/MMC one up on Radxa E20C
board. Both HS and SDR104 mode are verified.

This is based on v2 of the SARADC series[1]

- Changed from v1
  - Apply review tags
  - Rebase on top of linux-rockchip/for-next and saradc v2 series
  - rk3528 clock driver:
    - explicitly include minmax.h, replace MAX() with more robust max()
    - readability improvements
    - fix error checks: ERR_PTR(-ENODEV), instead of ERR_PTR(ENODEV), is
      returned when syscon_regmap_lookup_by_compatible() fails for missing
      such syscon
  - RK3528 devicetree
    - Add default pinctrl
    - Move the per-SoC property, rockchip,default-sample-phase, into the
      SoC devicetree
  - rk3528-radxa-e20c devicetree
    - Assign sdcard to mmc1
    - Add missing regulators
    - Apply no-sdio for the sdmmc controller
    - Sort nodes
  - Link to v1: https://lore.kernel.org/all/20250301104250.36295-1-ziyao@disroot.org/

Thanks for your time and review.
