[PATCH v2 0/2] Add support for Eswin EIC7700 SD/eMMC controller

[hehuan1@eswincomputing.com]

From: Huan He <hehuan1@eswincomputing.com>

Updates:

  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
