[PATCH v3 1/3] dt-bindings: clock: spacemit: Add clock controllers of Spacemit K1 SoC

Haylen Chu heylenay at 4d2.org
Tue Nov 26 06:31:24 PST 2024


Add definition for the clock controllers of Spacemit K1 SoC. The clock
tree is managed by several SoC parts thus different compatible strings
are introduced for each.
