[PATCH v3 0/4] clk: ti: add am33xx spread spectrum clock support

[Dario Binacchi]

As reported by the TI spruh73x RM, MPU and LCD modules support spread
spectrum clocking (SSC) on their output clocks. SSC is used to spread
the spectral peaking of the clock to reduce any electromagnetic
interference (EMI) that may be caused due to the clock’s fundamental
or any of its harmonics.
The series allows you to enable and adjust the spread spectrum clocking
for all am33xx PLLs for which it is supported.


Changes in v3:
- Add '-hz' suffix to "ti,ssc-modfreq" binding.
- Add Tony Lindgren acked tag.
- Use "ti,ssc-modfreq-hz" binding instead of "ti,ssc-modfreq".

Changes in v2:
- Remove SSC registers from dpll_core_ck@490 node (SSC is not supported)
- Add SSC registers to dpll_mpu_ck@488 node.
- Move the DT changes to the previous patch in the series.
