Subject: clk: mediatek: mt7988: convert to struct mtk_parent
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a2d600dba36ed487bd380197d3e197e74305099b;p=thirdparty%2Fu-boot.git

clk: mediatek: mt7988: convert to struct mtk_parent

Convert all parent clock arrays to use struct mtk_parent. This will
allow us to simplify core code later by having only one possible data
type for mux parent arrays.
