    - Update drive-impedance-ohm
    - Update the item of reset-names
  - Update sdhci-of-dwcmshc.c
    - Add descriptions for PHY registers
    - Simplify clock management(remove custom clock provider, use
      standard clk API)
    - Replace magic numbers with GENMASK() or FIELD_PREP() macros
    - Add comments explaining HSP stability assertion writes
    - Adjust line wrapping to fit within 100-column
    - Delete forward declarations by moving function definitions
    - Rename variable is_sdio to is_sd
    - Replace unclear macros with meaningful alternatives
  - Link to v2: https://lore.kernel.org/all/20250912093451.125-1-hehuan1@eswincomputing.com/

  Changes in v2:
  - Delete the previous separate driver and yaml binding file
  - Update snps,dwcmshc-sdhci.yaml to add support for Eswin EIC7700
    - Add the new compautible string: "eswin,eic7700-dwcmshc"
    - Add new properties: clock-output-names, '#clock-cells',
      drive-impedance-ohm, eswin,hsp-sp-csr and eswin,syscrg-csr
    - Add customized reset-names for EIC7700 platform
  - Update sdhci-of-dwcmshc.c to add support for Eswin EIC7700
    - Add a new struct eic7700_priv to hold Eswin-specific data,
      including clock phases, register mappings, and drive
      impedance configuration
    - Implement EIC7700-specific sdhci_ops
      - set_clock: support core clock configuration with phase delay
      - reset: add PHY reset and configuration
      - set_uhs_signaling: support HS400 DLL lock
      - platform_execute_tuning: implement delay line tuning and phase
        code adjustment
    - Add initialization routine (eic7700_init)
    - Integrate the new platform data and ops into the driver's match table
  - Link to v1: https://lore.kernel.org/all/20250516091259.774-1-dongxuyang@eswincomputing.com/
