Subject: arm64: dts: exynosautov920: add initial CMU clock nodes in ExynosAuto v920
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=4d06000979cda26e914552d486e5364248025fcd;p=linux.git

arm64: dts: exynosautov920: add initial CMU clock nodes in ExynosAuto v920

Add cmu_top, cmu_peric0 clock nodes and
switch USI clocks instead of dummy fixed-rate-clock.
