Hi,

This series adds clock support for SAMA7G5. The first patches in
series, patches 1/19-9/19, contains some fixes (let me know if
you want to send them as a separate series).

For SAMA7G5 clock support some AT91 clock drivers needed changes
because:
1/ some of generated, master and peripheral clocks could have
   changeable parents (being able to request frequency changes
   from parent)
2/ generated and programmable clocks parents needed a mux table
   as the hardware parent index doesn't correspond with software
   parent index
3/ there are 4 new master clocks, MCK1..4 (compared with previous
   AT91 architectures) which are controlled separately from MCK0
4/ some of the PLLs have 2 outputs the internal block schema being
   as follows:

   +------+            +--------+
   | FRAC |-----+----->| DIVPMC |--->
   +------+     |      +--------+
                |
                |      +--------+
                +----->|  DIVIO |--->
                       +--------+

   For this, the clk-sam9x60-pll driver has been re-factored.

Claudiu Beznea (19):
  clk: at91: clk-generated: continue if __clk_determine_rate() returns
    error
  clk: at91: clk-generated: check best_rate against ranges
  clk: at91: clk-sam9x60-pll: fix mul mask
  clk: at91: sam9x60-pll: use frac when computing pll frequency
  clk: at91: sam9x60-pll: use logical or for range check
  clk: at91: sam9x60-pll: check fcore against ranges
  clk: at91: sam9x60-pll: use frac when setting frequency
  clk: at91: sam9x60: fix main rc oscillator frequency
  clk: at91: sckc: register slow_rc with accuracy option
  clk: at91: replace conditional operator with double logical not
  clk: at91: clk-generated: pass the id of changeable parent at
    registration
  clk: at91: clk-generated: add mux_table option
  clk: at91: clk-master: add master clock support for SAMA7G5
  clk: at91: clk-peripheral: add support for changeable parent rate
  clk: at91: clk-programmable: add mux_table option
  clk: at91: add macro for pll ids mask
  clk: at91: clk-sam9x60-pll: re-factor to support plls with multiple
    outputs
  clk: at91: clk-utmi: add utmi support for sama7g5
  clk: at91: sama7g5: add clock support for sama7g5
