Subject: clk: sifive: Drop GEMGXL clock driver
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=8633edeb2a1de97f03cededf3c7fc8956bcec61e;p=u-boot.git

clk: sifive: Drop GEMGXL clock driver

The GEMGXL clock driver is now directly part of Cadence MACB
ethernet driver in upstream Linux kernel. There is no separate
GEMGXL clock driver in upstream Linux kernel hence we drop
GEMGXL clock driver from U-Boot as well.
