[PATCH v3 0/3] Add driver support for Eswin EIC7700 SoC SATA Controller and PHY

[Yulin Lu]

This series depends on the config option patch [1].

[1] https://lore.kernel.org/all/20250825132427.1618089-3-pinkesh.vaghela@xxxxxxxxxxxxxx/

Updates:
  v2 -> v3:
    - Use full name in "From" and "Signed-off-by" fields information.
    - eswin,eic7700-ahci.yaml
      - Remove the introduction to the reg, interrupts, phys, and phy-names fields.
      - Modify the usage of the clocks field in the examples.
      - Corrected the order of dt properties.
    - phy-eic7700-sata.c
      - Register operations use the GENMASK macro and FIELD_PREP instead of
        the original bit offset method, and add "#include <linux/bitfield.h>".
      - Modified some macro definition names.
      - Remove the redundant initialization assignments for "ret" and "val".
      - Delete ".suppress_bind_attrs = true".
      - Modify the driver name.
      - Add "#include <linux/io.h>" to fix the robot test issue.
    - Link to v2: https://lore.kernel.org/lkml/20250819134722.220-1-luyulin@xxxxxxxxxxxxxxxxxx/

  v2 -> v1:
    - Delete the original controller driver and use ahci_dwc.c instead.
    - Add eswin,eic7700-ahci.yaml
      - Correct the descriptions of reset, interrupt and other
        hardware resources for the sata controller on EIC7700 SoC.
      - The clocks for both sata controller and sata PHY are controlled
        via a register bit in the HSP bus and are not registered in the
        clock tree. Clock are managed within the PHY driver, therefore
        it is not described in this document.
      - Add $ref: snps,dwc-ahci-common.yaml#.
    - Add eswin,eic7700-sata-phy.yaml
      - Add this file to include the description of the PHY on EIC7700 SoC.
    - Add an eswin directory under the PHY driver path, and include the SATA
      PHY driver code for EIC7700 SoC.
    - Link to v1: https://lore.kernel.org/all/20250515085114.1692-1-hehuan1@xxxxxxxxxxxxxxxxxx/
