With closed loop support, the clock rate of the DFLL can be adjusted.

The oscillator itself in the DFLL is a free-running oscillator whose
rate is directly determined the supply voltage. However, the DFLL
module contains logic to compare the DFLL output rate to a fixed
reference clock (51 MHz) and make a decision to either lower or raise
the DFLL supply voltage. The DFLL module can then autonomously change
the supply voltage by communicating with an off-chip PMIC via either I2C
or PWM signals. This driver currently supports only I2C.

Add shared code to support the Tegra DFLL clocksource in open-loop
mode. This root clocksource is present on the Tegra124 SoCs. The
DFLL is the intended primary clock source for the fast CPU cluster.

This code is very closely based on a patch by Paul Walmsley from
December (http://comments.gmane.org/gmane.linux.ports.tegra/15273),
which in turn comes from the internal driver by originally created
by Aleksandr Frid <afrid@nvidia.com>.

Subsequent patches will add support for closed loop mode and drivers
for the Tegra124 fast CPU cluster DFLL devices, which rely on this
code.

The driver supports decoding and statically modelling PLL state (i.e.
we inherit state from bootloader) and provides support for all
peripherals that support simple one-bit gated clocks. The covers all
peripherals whose clocks come from the AHB, APB1 or APB2 buses.

It has been tested on an STM32F429I-Discovery board. The clock counts
for TIM2, USART1 and SYSTICK are all set correctly and the wall clock
looks OK when checked with a stopwatch. I have also tested a prototype
driver for the RNG hardware. The RNG clock is correctly enabled by the
framework (also did inverse test and proved that by changing DT to
configure the wrong clock bit then we observe the RNG driver to fail).

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:
  samsung: exynos4: add cpu clock configuration data and instantiate
  cpu clock")
- removed E5250_CPU_DIV[0,1](), E5420_EGL_DIV0() and E5420_KFC_DIV()
  macros for now

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:

Without use of CLK_GET_RATE_NOCACHE flag:

The clk-nomadik.o is built for ARCH_NOMADIK -- which is bool, and
hence this code is either present or absent.  It will never be
modular, so using module_init as an alias for __initcall can be
somewhat misleading.

Fix this up now, so that we can relocate module_init from
init.h into module.h in the future.  If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.

Note that direct use of __initcall is discouraged, vs. one
of the priority categorized subgroups.  As __initcall gets
mapped onto device_initcall, our use of device_initcall
directly in this change means that the runtime impact is
zero -- it will remain at level 6 in initcall ordering.

A recent change to mark parent names as const missed this struct
member so we get warnings like:

drivers/clk/pxa/clk-pxa25x.c:122:2: warning: initialization
discards 'const' qualifier from pointer target type

Fix it.

It adds a clock driver for zx296702 SoC to register the clock tree to
Common Clock Framework.  All the clocks of bus topology and some the
peripheral clocks are ready with this commit. Some missing leaf clocks
for peripherals will be added later when needed.

The debug_node field is only used when DEBUG_FS config is selected,
so declare it only if DEBUG_FS is selected.

Currently it is not made explicit why clk_fixed_set_rate() can ignore
its arguments and unconditionally return success. Add a comment
to explain this.

We also mark the clk_ops table const since it should never be
modified at runtime.

This patch adds 'CLK_IGNORE_UNUSED' flag to clocks which is required for
operation of secure monitor call (smc). System will hang when it executes 'smc'
with one of those clock is gated. All related clocks must be enabled.

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
of the MALI device.

This DIV_CPIF register must be stored when the system is suspended, and must
be restored on system resume. This patch adds the register to the list of
restored registers.

This patch adds CLK_SET_RATE_PARENT flag to support DVFS of Cortex-{A53|A57}
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.
- 'apollo' word means the LITTLE core (Cortex-A53 core) in Exynos5433 TRM.
- 'atlas' word means the big core (Cortex-A57 core) in Exynos5433 TRM.
