[PATCH v3 1/3] dt-bindings: clock: exynosautov9: add dpum clock

From: Kwanghoon Son <hidden>
Date: 2024-08-09 11:55:10
Also in: linux-arm-kernel, linux-clk, linux-samsung-soc, lkml
Subsystem: common clk framework, open firmware and flattened device tree bindings, samsung soc clock drivers, the rest · Maintainers: Michael Turquette, Stephen Boyd, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Sylwester Nawrocki, Chanwoo Choi, Peter Griffin, Linus Torvalds

Add dpum clock definitions and compatibles.

Also used clock name 'bus' instead of full clock name
dout_clkcmu_dpum_bus like other board cmu schema (GS101).
