2019-11-07clk: qcom: Initialize clock drivers earlierAmit Kucheria1-1/+1
Initialize the clock drivers on sdm845 and qcs404 in core_initcall so we can have earlier access to cpufreq during booting.

2019-09-09clk: qcom: gcc-qcs404: Use floor ops for sdcc clksVinod Koul1-2/+2
Update the gcc qcs404 clock driver to use floor ops for sdcc clocks. As disuccsed in [1] it is good idea to use floor ops for sdcc clocks as we dont want the clock rates to do round up.

2019-08-08clk: qcom: Add WCSS gcc clock control for QCS404Govind Singh1-0/+30
Add support for the WCSS QDSP gcc clock control used on qcs404 based devices. This would allow wcss remoteproc driver to control the required gcc clocks to bring the subsystem out of reset. Signed-off-by: Govind Singh <govinds@codeaurora.org> Signed-off-by: Stephen Boyd <sboyd@kernel.org>

2019-02-22clk: qcom: Make common clk_hw registrationsJeffrey Hugo1-7/+2
Several clock controller drivers define a list of clk_hw devices, and then register those devices in probe() before using common code to process the rest of initialization. Extend the common code to accept a list of clk_hw devices to process, thus eliminating many duplicate implementations.
