X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=024b84f661674dcfa1341c90ce654c485c4ab756;p=thirdparty%2Flinux.git

clk: spacemit: define three reset-only CCUs

Three CCUs on the SpacemiT K1 SoC implement only resets, not clocks.
Define the CCU data for these resets so their auxiliary devices get
created.
