Subject: [PATCH net-next v3 0/6] microchip_t1s: Update on Microchip 10BASE-T1S PHY driver

This patch series contain the below updates,
- Fixes on the Microchip LAN8670/1/2 10BASE-T1S PHYs support in the
  net/phy/microchip_t1s.c driver.
- Adds support for the Microchip LAN8650/1 Rev.B0 10BASE-T1S Internal
  PHYs in the net/phy/microchip_t1s.c driver.

Changes:
v2:
- Updated cover letter contents.
- Modified driver description is more generic as it is common for all the
  Microchip 10BASE-T1S PHYs.
- Replaced read-modify-write code with phy_modify_mmd function.
- Moved */ to the same line for the single line comments.
- Changed the type int to u16 for LAN865X Rev.B0 fixup registers
  declaration.
- Changed all the comments starting letter to upper case for the
  consistency.
- Removed return value check of phy_read_mmd and returned directly in the
  last line of the function lan865x_revb0_indirect_read.
- Used reverse christmas notation wherever is possible.
- Used FIELD_PREP instead of << in all the places.
- Used 4 byte representation for all the register addresses and values
  for consistency.
- Comment for indirect read is modified.
- Implemented "Reset Complete" status polling in config_init.
- Function lan865x_setup_cfgparam is split into multiple functions for
  readability.
- Reference to AN1760 document is added in the comment.
- Removed interrupt disabling code as it is not needed.
- Provided meaningful macros for the LAN865X Rev.B0 indirect read
  registers and control.
- Replaced 0x10 with BIT(4).
- Removed collision detection disable/enable code as it can be done with
  a separate patch later.

v3:
- Comment for phy_modify_mmd() is extended to indicate that the write is
  not required if the register already has the required value.
- Commit message is updated for the not supported hardware revisions
  0x0007C160 (Rev.A0) and 0x0007C161 (Rev.B0) since they are never
  released to production.
- Commit message is updated to indicate that the Reset Complete interrupt
  will be cleared when the STS2 register read is done.
- Corrected the typo in the offset calculation comment.
- Used reverse christmas notation for the local variable declarations.

Parthiban Veerasooran (6):
  net: phy: microchip_t1s: modify driver description to be more generic
  net: phy: microchip_t1s: replace read-modify-write code with
    phy_modify_mmd
  net: phy: microchip_t1s: update LAN867x PHY supported revision number
  net: phy: microchip_t1s: fix reset complete status handling
  net: phy: microchip_t1s: remove unnecessary interrupts disabling code
  net: phy: microchip_t1s: add support for Microchip LAN865x Rev.B0 PHYs
