Gabriel FERNANDEZ 5f7aa9071e clk: st: Support for QUADFS inside ClockGenB/C/D/E/F
The patch supports the 216/432/660 type Quad Frequency Synthesizers
used by ClockGenB/C/D/E/F

QUADFS clock : It includes support for all 216/432/660 type Quad
Frequency Synthesizers : implemented as Fixed Parent / Rate / Gate clock,
with clock rate calculated reading H/w settings done at BOOT.

QuadFS have 4 outputs : chan0 chan1 chan2 chan3

Gabriel FERNANDEZ b9b8e614b5 clk: st: Support for PLLs inside ClockGenA(s)
The patch supports the c65/c32 type PLLs used by ClockGenA(s)

PLL clock : It includes support for all c65/c32 type PLLs
inside ClockGenA(s) : implemented as Fixed Parent / Fixed Rate clock,
with clock rate calculated reading H/w settings done at BOOT.

c65 PLLs have 2 outputs : HS and LS
c32 PLLs have 1-4 outputs : ODFx

Gabriel FERNANDEZ 94885faf9d clk: st: Support for DIVMUX and PreDiv Clocks
The patch supports the DIVMUX and PreDiv clocks used by ClockGenA(s)

DIVMUX clock : Divider-Multiplexer-Gate inside ClockGenA(s)
It includes support for each channel : 3-parent Multiplexer,
Divider for each Parent, Gate to switch OFF the output channel. The
clock is implemented using generic clocks implemented in the kernel
clk_divider and clk_mux.

PreDiv clock : Fixed Divider Clock used inside ClockGenA(s) to divide
the oscillator clock by factor-of-16. The clock is implemented using
generic clocks implemented in the kernel clk_divider.
