Subject: [PATCH net-next v4 0/4] net: phy: mscc: Add support for PHY LED control

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Hi All,

This patch series adds support for controlling the PHY LEDs on the
VSC85xx family of PHYs from Microsemi (now part of Renesas).
The first two patches simplify and consolidate existing probe code
the third patch introduces the LED control functionality.
The LED control feature allows users to configure the LED behavior
based on link activity, speed, and other criteria.

v3->v4:
- Sorted the members of vsc85xx_probe_config struct to avoid the
  holes
- Fixed Reverse Christmas tree in vsc85xx_led_combine_disable_set()
- Added Reviewed-by tag
- Added new patch 4/4 to handle devm_phy_package_join()
  failure in vsc85xx_probe_common()

v2->v3:
- Added Reviewed-by tag to patches 1/3 and 3/3.
- Grouped check_rate_magic check in patch 2/3.
- Formatted the patches with `--diff-algorithm=patience` option to
  improve readability.

v1->v2:
- Patches 1/3 and 2/3 are new.
- Added LED control support to all VSC85xx PHY variants.
- Renamed led callbacks to vsc85xx_* for consistency.
- Defaulted the LEDs on probe to the default array before parsing DT.
- Used phy_modify() in vsc85xx_led_brightness_set()
- Return value of phy_read() checked in vsc85xx_led_hw_control_get()
- Reverse Christmas tree in vsc85xx_led_hw_is_supported()
- Updated the commit message to clarify the LED combine feature behavior.

Cheers,
Prabhakar
