Subject: [PATCH] arm64: dts: ls1088a: specify clock frequencies for the MDIO controllers
Git-commit: d78a57426e64fc4c61e6189e450a0432d24536ca
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: bbe75af7b092 ("arm64: dts: ls1088a: add external MDIO device nodes")
