Subject: [PATCH net-next v3 00/17] net: dsa: microchip: add error handling and register access validation

changes v3:
- fix build error in the middle of the patch stack.

changes v2:
- add regmap_ranges for KSZ9477
- drop output clock devicetree in driver validation patches. DTs need
  some more refactoring and can be done in a separate patch set.
- remove some unused variables.

This patch series adds error handling for the PHY read/write path and optional
register access validation.
After adding regmap_ranges for KSZ8563 some bugs was detected, so
critical bug fixes are sorted before ragmap_range patch.

Potentially this bug fixes can be ported to stable kernels, but need to be
reworked.

Oleksij Rempel (17):
  net: dsa: microchip: add separate struct ksz_chip_data for KSZ8563
    chip
  net: dsa: microchip: do per-port Gbit detection instead of per-chip
  net: dsa: microchip: don't announce extended register support on non
    Gbit chips
  net: dsa: microchip: allow to pass return values for PHY read/write
    accesses
  net: dsa: microchip: forward error value on all ksz_pread/ksz_pwrite
    functions
  net: dsa: microchip: ksz9477: add error handling to ksz9477_r/w_phy
  net: dsa: microchip: ksz8795: add error handling to ksz8_r/w_phy
  net: dsa: microchip: KSZ9893: do not write to not supported Output
    Clock Control Register
  net: dsa: microchip: add support for regmap_access_tables
  net: dsa: microchip: add regmap_range for KSZ8563 chip
  net: dsa: microchip: ksz9477: remove MII_CTRL1000 check from
    ksz9477_w_phy()
  net: dsa: microchip: add regmap_range for KSZ9477 chip
  net: dsa: microchip: ksz9477: use internal_phy instead of phy_port_cnt
  net: dsa: microchip: remove unused port phy variable
  net: dsa: microchip: ksz9477: remove unused "on" variable
  net: dsa: microchip: remove unused sgmii variable
  net: dsa: microchip: remove IS_9893 flag
