clk: qcom: support for dynamic updating the PLL
Some of the Alpha PLLs support dynamic update in which the
frequency can be changed dynamically without turning off the PLL.
This dynamic update requires the following sequence:
1. Write the desired values to L_VAL and ALPHA_VAL registers
2. Toggle pll_latch_input from low to high
3. Wait for pll_ack_latch to transition from low to high
The new L and alpha values have been latched. It may
take some time for the PLL to fully settle with these
new values.
4. Pull pll_latch_input low
