Subject: [PATCH net-next v2 0/2] net: phy: dp83822: Add support for GPIO2
 clock output

The DP83822 has several clock configuration options for pins GPIO1, GPIO2
and GPIO3. Clock options include:
  - MAC IF clock
  - XI clock
  - Free-Running clock
  - Recovered clock
This patch adds support for GPIO2, the support for GPIO1 and GPIO3 can be
easily added if needed. Code and device tree bindings are derived from
dp83867 which has a similar feature.

Changes in v2:
- Move MII_DP83822_IOCTRL2 before MII_DP83822_GENCFG
- List case statements together, and have one break at the end.
- Move dp83822->set_gpio2_clk_out = true at the end of the validation
- Link to v1: https://lore.kernel.org/r/20241209-dp83822-gpio2-clk-out-v1-0-fd3c8af59ff5@liebherr.com
