net: phy: micrel: allow usage of generic ethernet-phy
From: Heiko Stuebner <heiko.stuebner@...> Date: Sat, 18 Nov 2023 23:28:25 +0100
Commit-Message
The generic ethernet-phy binding allows describing an external clock since commit 350b7a258f20 ("dt-bindings: net: phy: Document support for external PHY clk") for cases where the phy is not supplied by an oscillator but instead by a clock from the host system. And the old named "rmii-ref" clock from 2014 is only specified for phys of the KSZ8021, KSZ8031, KSZ8081, KSZ8091 types. So allow retrieving and enabling the optional generic clock on phys that do not provide a rmii-ref clock. Signed-off-by: Heiko Stuebner <heiko.stuebner@...>
