Hi all,
This patchset adds device tree nodes for Exynos990 CMUs (TOP and HSI0).
CMU_TOP is the top block. It provides clocks for other blocks.
CMU_HSI0 is a block for USB31. It provides clocks for the USB phy and
other USB hardware.
This patchset allows these first two implemented CMU blocks to be used.
Changes since v2:
- REALLY fix the stray blank line (Thanks again, Krzysztof!) [0]
- Rewrite cover letter. (Thanks, Krzysztof!)
- Use b4's single patch format.
[0] I didn't amend the commit. Stupid mistake. Sorry for wasting time
with v2.
Changes since v1:
- Fix clock-names formatting (Thanks, Krzysztof!)
- Remove stray blank line (Thanks, Krzysztof!)
- Make clock-names conform with the binding style
Best regards,
Igor
