Subject: [PATCH 07/13] clk: qcom: cpu-8996: setup PLLs before registering clocks
Date: Wed, 11 Jan 2023 22:19:58 +0300	[thread overview]
Message-ID: <20230111192004.2509750-8-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20230111192004.2509750-1-dmitry.baryshkov@linaro.org>

Setup all PLLs before registering clocks in the common clock framework.
This ensures that the clocks are not accessed before being setup in the
known way and that the CCF is in sync with the actual HW programming.
