[v2,00/12] initial clock support for exynosauto v9 SoC

Message

Chanho Park May 3, 2022, 10:59 a.m. UTC

This patchset adds initial clock driver support for Exynos Auto v9 SoC.
This driver is highly inspired from exynos850 clock driver. Like
exynos850, this does not use Q-channel control & Hardware automatic
clock gating. So, all the gate clocks will be controlled by CCF & CMU
driver.

Below CMU blocks are supported in this patchset and remains will be
implemented later.

- CMU_TOP
- CMU_BUSMC
- CMU_CORE
- CMU_FSYS2
- CMU_PERIC0
- CMU_PERIC1
- CMU_PERIS

Changes from v1:
- Adjust patch order to avoid dt-binding check bot's build warning
- Rename exynosautov9.h to samsung,exynosautov9.h (Suggested by
  Krzystof)
- clock nodes of exynosautov9.dtsi are aligned by unit address order.
- Each clock items are listed to every own line.
- Added Krzystof RB tags.
