Subject: clk: mediaTek: mt8518: add clock tree type flags
X-Git-Tag: v2026.10-rc1~17^2~36
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=eac5696bb83cee4ae63e96da1f547f7e1a48752a;p=thirdparty%2Fu-boot.git

clk: mediaTek: mt8518: add clock tree type flags

Add clock tree type flags to the mt8518 clock tree structures. These
will be used later for parent lookup.

Clock trees had to be split now that each tree has a different type
flag.
