Subject: [PATCH] arm64: dts: lx2160a: specify clock frequencies for the MDIO controllers
Git-commit: c126a0abc5dadd7df236f20aae6d8c3d103f095c
Patch-mainline: v6.1-rc4
References: git-fixes
Up until now, the external MDIO controller frequency values relied
either on the default ones out of reset or on those setup by u-boot.
Let's just properly specify the MDC frequency in the DTS so that even
without u-boot's intervention Linux can drive the MDIO bus.
Fixes: 6e1b8fae892d ("arm64: dts: lx2160a: add emdio1 node")
Fixes: 5705b9dcda57 ("arm64: dts: lx2160a: add emdio2 node")
