Subject: [PATCH 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.
