A system-controller register region named "OLB" has some control over the Ethernet PHY integration. Extend the current OLB ecosystem with a new generic PHY driver. - OLB is carried by one main platform driver: clk-eyeq. - It instantiates auxiliary devices: reset-eyeq & pinctrl-eyeq5. - We add a new one: phy-eyeq5-eth. About related patches: - The MACB series [1] has been merged in v6.19-rc1. It makes MACB consume a generic PHY from devicetree with the EyeQ5 compatible. - clk patches are incoming to make clk-eyeq instantiate this new auxiliary device. They also ensure we get a dev->of_node assigned. Patches used to be [2] in the same series. - MIPS patches are incoming to add MACB/GEM instances in devicetree and their associated PHYs. They also update dt-bindings to reflect this new feature OLB provides. Patches used to be [2] in the same series. Have a nice day, Thanks!

Drop priv->dev field that is unused. - Call into phy_exit() from phy_init() as the sequence is the same. Add comment to explain the reasoning. - Take Reviewed-by: Luca on "phy: sort Kconfig and Makefile". - Rebase onto v7.0-rc1 and test on EyeQ5. Only diff to report: PHY_COMMON_PROPS and PHY_COMMON_PROPS_TEST are kept at the top in the sorting patch; we do not strictly respect an alphabetical ordering. - Link to v6: https://lore.kernel.org/r/20260127-macb-phy-v6-0-cdd840588188@bootlin.com Changes in v6: - Rebase upon v6.19-rc7; nothing to report. - Add new patch "phy: sort Kconfig and Makefile". - phy-eyeq5-eth: drop useless explicit __iomem cast to dev_get_platdata() return value. - I did *not* drop the Kconfig `default MACH_EYEQ5` nor driver `dev_dbg()`. I think both are useful and should be kept.
