Subject: [PATCH v2 5/6] clk: samsung: exynos850: Add AUD and HSI main gate clocks
Add main gate clocks for controlling AUD and HSI CMUs:
- gout_aud_cmu_aud_pclk
- gout_hsi_cmu_hsi_pclk
Those clocks were marked as CLK_IGNORE_UNUSED, as system hangs on
boot otherwise.
While at it, add missing PPMU (Performance Profiling Monitor Unit)
clocks for CMU_HSI.
Signed-off-by: Sam Protsenko <semen.protsenko@...aro.org>
---
Changes in v2:
- Rebased on top of most recent soc/for-next tree
- Added comment for CLK_IGNORE_UNUSED flag usage
