RK3528 features two SDIO controllers and one SD/MMC controller. This
series brings the SD/MMC one up on Radxa E20C board. Both HS and SDR104
modes are verified.

- Changed from v5

- Changed from v4
  - rk3528 clock driver
    - Switch to auxiliary GRF
    - drop rockchip_clk_register_grf_branches
    - Rename branch_mmc_grf to branch_grf_mmc to make style consistent
      (with branch_grf_gate)
  - Link to v4: https://lore.kernel.org/all/20250417143647.43860-1-ziyao@disroot.org/

- Changed from v2
  - Apply review tags
  - Rebase on top of linux-rockchip/for-next and drop applied patches
  - RK3528 devicetree
    - Fix accidentally dropped status property of saradc node
    - drop det and pwren pinctrls for SDIO{0,1} according to the
      reference design
    - Correct max-frequency for SDIO{0,1}
  - rk3528-radxa-e20c devicetree
    - Don't disable sdio for sdmmc as claimed in the hw design guide

  - 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
