This patch adds the CLK_SET_RATE_PARENT flag for 'aclk_g3d' clock and parent
clocks becuase 'aclk_g3d' is used to change GPU frequency for DVFS (Dynamic
Voltage Frequency Scaling) feature and adds CLK_IGNORE_UNUSED flags to
'aclk_asyncapbs_g3d'/'aclk_asyncapbm_g3d' clocks to access the SFR

core (big.LITTLE core) because 'sclk_{apollo|atlas}' leaf clock is used to
change the CPU frequency of Cortex-{A53|A57} core in arm_big_little.c driver.

Use of_clk_parent_fill to fill in the parent clock's array.
Signed-off-by: NDinh Nguyen <dinguyen@opensource.altera.com>
Signed-off-by: NStephen Boyd <sboyd@codeaurora.org>

Sprinkled all through the platform clock drivers are code like this to
fill the clock parent array:

for (i = 0; i < num_parents; ++i)
	parent_names[i] = of_clk_get_parent_name(np, i);

The of_clk_parent_fill() will do the same as the code above, and while
at it, return the number of parents as well since the logic of the
function is to the walk the clock node to look for the parent.

Currently, when the rate is changed, the driver makes sure the
PLL is enabled before doing so. This is done because the PLL
cannot be locked while disabled. Once locked, the drivers
returns the PLL to its previous enable/disable state.

This is a bit cumbersome, and can be simplified.

This commit reworks the .set_rate() functions for the integer
and fractional PLLs. Upon rate change, the PLL is now locked
only if it's already enabled.

Also, the driver locks the PLL on .enable(). This makes sure
the PLL is locked when enabled, and not locked when disabled.

This driver supports the TI CDCE925 programmable clock synthesizer.
The chip contains two PLLs with spread-spectrum clocking support and
five output dividers. The driver only supports the following setup,
and uses a fixed setting for the output muxes:
  Y1 is derived from the input clock
  Y2 and Y3 derive from PLL1
  Y4 and Y5 derive from PLL2
Given a target output frequency, the driver will set the PLL and
divider to best approximate the desired output.

Add clock drivers for hi6220 SoC, this driver controls the SoC
registers to supply different clocks to different IPs in the SoC.

We add one divider clock for hi6220 because the divider in hi6220
also has a mask bit but it doesnot obey the rule defined by flag
"CLK_DIVIDER_HIWORD_MASK", we can not get index of the mask bit by
left shift fixed bits (e.g. 16 bits), so we add this divider clock
to handle it.
