Rajendra Nayak feb65645c1 clk: qcom: Add support for alpha pll hwfsm ops
Some PLLs can support an HW FSM mode (different from the Votable FSMs,
though its the same bit used to enable Votable FSMs as well as HW FSMs)
which enables the HW to do the bypass/reset/enable-output-ctrl sequence
on its own. So all thats needed from SW is to set the FSM_ENA bit.
PLL_ACTIVE_FLAG is whats used to check if the PLL is active/enabled.

Some of the PLLs which support HW FSM can also need an OFFLINE request
that needs to be toggled across the enable/disable. We use a flag to
identify such cases and handle them.

Stephen Boyd 8ff1f4c4c4 clk: qcom: Add Alpha PLL support
Add support for configuring rates of, enabling, and disabling
Alpha PLLs. This is sufficient for the types of PLLs found in
the global and multimedia clock controllers.
