X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=3dc80934f4651a3ef243a393be04b1f7f71daf24;p=u-boot.git

net: gem: Do not setup any clock for Xilinx SoC Versal

Xilinx SoC Versal is using fixed clock where setting rate is not supported.
That's why workaround the driver till real clock driver is supported.
