7705bb7176 clk: qcom: mmcc-msm8996: leave all mmagic gdscs and clocks always enabled
There's no bus infrastructure today to handle all the mmagic bus
clocks and GDSCs needed by all the multimedia blocks in msm8996, like
mdss, video, camera and gpu. Mark all these clocks with a CLK_IS_CRITICAL
and GDSCs with a ALWAYS_ON flag for now so they are left always enabled.
This patch should be reverted at some point when we do have a bus driver
to manage these clocks and GDSCs.

28d3f06e56 clk: qcom: support for alpha pll properties
Alpha PLL is a generic name used for QCOM PLLs which uses L and
Alpha values for configuring the integer and fractional part.
QCOM SoCs use different types of Alpha PLLs for which basic
software configuration part is common with following differences.

  1. All these PLLs have the same basic registers like
     PLL_MODE, L_VAL, ALPHA_VAL but some of the register offsets are
     different between PLLs types.

  2. The dynamic programming sequence is different in some
     of the Alpha PLLs

  3. Some of the PLLs don’t have 64 bit config control, 64 bit
     user control, VCO configuration, etc.

96893e101e clk: qcom: Put venus core0/1 gdscs to hw control mode
The venus video ip's internal core blocks are under the
control of the firmware and their powerdomains needs to be
'ON' only when used by the firmware. So putting it into
hw controlled mode lets this to happen, otherwise the firmware
hangs checking for this.

120c155283 clk: qcom: Migrate to clk_hw based registration and OF APIs
Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers in this driver, allowing us to
move closer to a clear split of consumer and provider clk APIs.

9ffee1c4be clk: qcom: mmcc-8996: Remove clocks that should be controlled by RPM
The branch clocks MMSS_MMAGIC_AXI_CLK and MMAGIC_BIMC_AXI_CLK are
controlled by RPM when the APPs processor enable or disable the
RPM_MMAXI_CLK.

During the boot sequence, someone can enable the RPM_MMAXI_CLK, resulting
in register status bits showing that these clocks are enabled, our
clock driver may look at the enabled status of these clocks and try to
disable them since it thinks they are unused.

Don't make the clock driver touch these clocks.
