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
