cpufreq-dt: add 'boost' mode frequencies support
Add 'boost' mode frequencies support:
- add boost-opps binding to cpufreq-dt driver bindings
- make cpufreq_init() adjust freq_table accordingly
- fix set_target() to handle boost frequencies
- add boost_supported field to struct cpufreq_dt_platform_data
- set dt_cpufreq_driver.boost_supported in dt_cpufreq_probe()
This patch makes cpufreq-dt driver aware of 'boost' mode frequencies
and prepares it for adding support for Exynos4x12 'boost' support.
boost-opps binding is currently limited to cpufreq-dt but once there is
a need for cpufreq wide and/or generic Linux device support for 'boost'
mode cpufreq-dt can be updated to handle the new code without changing
the binding itself.
The decision to make 'boost' mode support limited to cpufreq-dt driver
for now was taken because 'boost' mode is currently a niche feature and
code needed for parsing boost-opps binding is minimal and simple. More
generic (i.e. separate 'boost' OPPs list in struct device and generic
cpufreq convertion of them to freq_table format) support would need far
more code and effort to make it work. Doing it without a demonstrated
real need would be on overengineering IMHO.

clk: samsung: add infrastructure to register cpu clocks
The CPU clock provider supplies the clock to the CPU clock domain. The
composition and organization of the CPU clock provider could vary among
Exynos SoCs. A CPU clock provider can be composed of clock mux, dividers
and gates. This patch defines a new clock type for CPU clock provider and
adds infrastructure to register the CPU clock providers for Samsung
platforms.
Changes by Bartlomiej:
- fixed issue with setting lower dividers before the parent clock speed
was lowered (the issue resulted in lockup on Exynos4210 SoC based
Origen board when "ondemand" cpufreq governor was stress tested)
- fixed missing spin_unlock on error in exynos_cpuclk_post_rate_change()
problem by moving cfg_data search outside of the spin locked area
- removed leftover kfree() in exynos_register_cpu_clock() that could
result in dereferencing the NULL pointer on error
- moved spin_lock earlier in exynos_cpuclk_pre_rate_change() to cover
reading of E4210_SRC_CPU and E4210_DIV_CPU1 registers
- added missing "last chance" checks to wait_until_divider_stable() and
wait_until_mux_stable() (needed in case that IRQ handling took long
time to proceed and resulted in function printing incorrect error
message about timeout)
- moved E4210_CPU_DIV[0,1]() macros just before their only users,
this resulted in moving them from patch #2 to patch #3/6 ("clk:

clk: add CLK_RECALC_NEW_RATES clock flag for Exynos cpu clock support
This flag is needed to fix the issue with wrong dividers being setup
by Common Clock Framework when using the new Exynos cpu clock support.
The issue happens because clk_core_set_rate_nolock() calls
clk_calc_new_rates(clk, rate) before both pre/post clock notifiers have
a chance to run. In case of Exynos cpu clock support pre/post clock
notifiers are registered for mout_apll clock which is a parent of armclk
cpu clock and dividers are modified in both pre and post clock notifier.
This results in wrong dividers values being later programmed by
clk_change_rate(top). To workaround the problem CLK_RECALC_NEW_RATES
flag is added and it is set for mout_apll clock later so the correct
divider values are re-calculated after both pre and post clock notifiers
had run.
For example when using "performance" governor on Exynos4210 Origen board
the cpufreq-dt driver requests to change the frequency from 1000MHz to
1200MHz and after the change state of the relevant clocks is following:

but the next one hang just after powering down of secondary CPUs (system
consumed energy as it would be running but was not responsive).
The issue was caused by enabling delayed reset assertion for CPU0 just
after issuing power down of cores. This was introduced for Exynos4 in
13cfa6c4f7fa ("ARM: EXYNOS: Fix CPU idle clock down after CPU off").
The whole behavior is not well documented but after checking with vendor
code this should be done like this (on Exynos4):
1. Enable delayed reset assertion when system is running (for all CPUs).
2. Disable delayed reset assertion before suspending the system.
This can be done after powering off secondary CPUs.
3. Re-enable the delayed reset assertion when system is resumed.
