Series Add CMU_PERIS support for Exynos990 SoC | expand

Commit Message

Igor Belwon Jan. 4, 2025, 8:05 p.m. UTC 
The CMU_PERIS block is used for clocking the MCT, and has one dependency
clock from CMU_TOP. As the MCT is initialized early, this CMU is also
registered early.

While at it, make the parent clock list comment spaced out correctly,
and add it to the HSI0 block.
