The "arm,no-tick-in-suspend" property was introduced to note
implementations where the system counter does not quite follow the ARM
specification that it "must be implemented in an always-on power
domain".
Particularly, RK3399's counter stops ticking when we switch from the
24MHz clock to the 32KHz clock in low-power suspend, so let's mark it as
such.

This patch updates the dynamic-power-coefficient for big cluster on
rk3399 SoCs.
The dynamic power consumption of the CPU is proportional to the square of
the Voltage (V) and the clock frequency (f). The coefficient is used to
calculate the dynamic power as below -
Pdyn = dynamic-power-coefficient * V^2 * f
Where Voltage is in uV, frequency is in MHz.
As the following is the tested data on rk3399's big cluster.
frequency(MHz) Voltage(V) Current(mA) Dynamic-power-coefficient
24 0.8 15
48 0.8 23 ~417
96 0.8 40 ~443
216 0.8 82 ~438
312 0.8 115 ~430
408 0.8 150 ~455
So the dynamic-power-coefficient average value is about 436.

Provide the dynamic power coefficient of the big and little CPU
clusters. These numbers are currently in use on the Samsung Chromebook
Plus ("Kevin").
The power allocator thermal governor doesn't know how to do anything if
it doesn't get power parameters from its cooling devices (in this case,
CPUfreq). So this effectively enables the power-allocator governor.

Clean up the init code and move the creation of factor clocks to the
appropriate positions coming from the clock architecture diagrams.
This also unifies the artificial separation of the hclk_vcodec etc clocks
again.
We do keep the separate definition of some watchdog and usb480m pseudo
clocks for now, as they're not real factor clocks from the clock-tree
but placeholders for fixes to come (usb480m gets supplied by the
missing driver for the new usbphy type and the watchdog-gate is sitting
somewhere else together which we cannot model currently).

rockchip_clk_register_ddrclk should not return NULL when failing
to call clk_register, otherwise rockchip_clk_register_branches
prints "unknown clock type". The actual case is that it's a known
clock type but we fail to register it, which may makes user confuse
the reason of failure. And the pr_err here is pointless as
rockchip_clk_register_branches will also print the similar message.

Currently the fractional divider clock time can't handle the
CLK_SET_RATE_PARENT flag. This is because, unlike normal dividers,
there is no clk_divider_bestdiv() function to try speeding up the parent
to see if it helps things.
Eventually someone could try to figure out how to make fractional
dividers able to use CLK_SET_RATE_PARENT, but until they do let's not
confuse the common clock framework (and anyone using it) by setting the
flag.

Usually, the 800MHz and 1GHz are supplied for CPLL and NPLL in the RK3399.
But dues to the carelessly copying from RK3036 when the RK3399 bringing up,
the refdiv == 6, it will increase the lock time, and it is not an optimal
configuration.
Let's fix them for the lock time and jitter are lower:
800 MHz:
- FVCO == 2.4 GHz, revdiv == 1.
1 GHz:
- FVCO == 3 GHz, revdiv == 1.

The PMU Cortex M0 on rk3399 is intended to be used for things like
DDRFreq transitions, suspend/resume, and other things that are the
purview of ARM Trusted Firmware and not the kernel. As such, the
kernel shouldn't be messing with the clocks. Add CLK_IGNORE_UNUSED to
these clocks.
Without this change, the following was observed on a Chromebook with a
rk3399 (using not-yet-upstream ARM Trusted Firmware code and
not-yet-upstream kernel code based on kernel-4.4):
1. We init the clock framework.
2. We start up "DDRFreq", which causes ATF to occasionally fire up the
M0 for transitions. Each time ATF fires up the M0 it will turn on
these clocks and each time it is done it will turn them off.
3. We finally get to the the part of the kernel that calls
clk_disable_unused() and we disables the clocks.
You can see the race above. Basically everything is fine as long as
ARM Trusted Firmware isn't starting up the M0 at exactly the same time
that the kernel is disabling unused clocks. ...but if the race
happens then we go boom.
