Critical clocks are those which must not be gated, else undefined
or catastrophic failure would occur. Here we have chosen to
ensure the prepare/enable counts are correctly incremented, so as
not to confuse users with enabled clocks with no visible users.

The drivers/clk/mvebu directory is only being built when
CONFIG_PLAT_ORION=y. As we are going to support additional mvebu
platforms in drivers/clk/mvebu, which don't have CONFIG_PLAT_ORION=y,
we need to recurse into this directory regardless of the value of
CONFIG_PLAT_ORION.
Since all files in drivers/clk/mvebu/ are already conditionally
compiled depending on various Kconfig options, we can recurse
unconditionally into drivers/clk/mvebu without any other change.

Merge tag 'bcm2835-clk-next-2016-03-17' of git://github.com/anholt/linux into clk-next
This pull request against clk/clk-next brings in fixes for fractional
clocks on 2835, add the PCM clock that used to be driven directly by
the bcm2835-i2s driver (that driver has been broken since this driver
was introduced), and adds many other new clocks.
* tag 'bcm2835-clk-next-2016-03-17' of git://github.com/anholt/linux:
clk: bcm2835: add missing osc and per clocks
clk: bcm2835: add missing PLL clock dividers
clk: bcm2835: enable management of PCM clock
clk: bcm2835: reorganize bcm2835_clock_array assignment
clk: bcm2835: remove use of BCM2835_CLOCK_COUNT in driver
clk: bcm2835: expose raw clock-registers via debugfs
clk: bcm2835: clean up coding style issues
clk: bcm2835: correctly enable fractional clock support
clk: bcm2835: divider value has to be 1 or more
clk: bcm2835: add locking to pll*_on/off methods
clk: bcm2835: pll_off should only update CM_PLL_ANARST
Drivers for these don't exist yet so we will add them as fixed clocks
so we don't BUG() if we change clocks that reference these clocks.

new device support in terms of LoC, but there has been some cleanup
in the core as well as the usual minor clk additions to various
drivers.
Core:
- parent tracking has been simplified
- CLK_IS_ROOT is now a no-op flag, cleaning up drivers has started
- of_clk_init() doesn't consider disabled DT nodes anymore
- clk_unregister() had an error path bug squashed
- of_clk_get_parent_count() has been fixed to only return unsigned ints
- HAVE_MACH_CLKDEV is removed now that the last arch user (ARM) is gone
New Drivers:
- NXP LPC18xx creg
- QCOM IPQ4019 GCC
- TI dm814x ADPLL
- i.MX6QP
Updates:
- Cyngus audio clks found on Broadcom iProc devices
- Non-critical fixes for BCM2385 PLLs
- Samsung exynos5433 updates for clk id errors, HDMI support,
suspend/resume simplifications
- USB, CAN, LVDS, and FCP clks on shmobile devices
- sunxi got support for more clks on new SoCs and went through a minor
refactoring/rewrite to use a simpler factor clk construct
- rockchip added some more clk ids and added suport for fraction dividers
- QCOM GDSCs in msm8996
- A new devm helper to make adding custom actions simpler (acked by Greg)

Reorganize bcm2835_clock_array so that there is no more
need for separate bcm2835_*_data structures to be defined.
Instead the required structures are generated inline via
helper macros.
To allow this to also work for pll alone it was required that
the parent_pll was changed from a pointer to bcm2835_pll_data
to the name of the pll instead.

As the use of BCM2835_CLOCK_COUNT in
include/dt-bindings/clock/bcm2835.h is frowned upon as
it needs to get modified every time a new clock gets introduced
this patch changes the clk-bcm2835 driver to use a different
scheme for registration of clocks and pll, so that there
is no more need for BCM2835_CLOCK_COUNT to be defined.

The current driver calculates the clock divider with
fractional support enabled.
But it does not enable fractional support in the
control register itself resulting in an integer only divider,
but in clk_set_rate responds back the fractionally divided
clock frequency.
This patch enables fractional support in the control register
whenever there is a fractional bit set in the requested clock divider.
Mash clock limits are are also handled for the PWM clock
applying the correct divider limits (2 and max_int) applicable to
basic fractional divider support (mash order of 1).
It also adds locking to protect the read/modify/write cycle of
the register modification.

Current clamping of a normal divider allows a value < 1 to be valid.
A divider of < 1 would actually only be possible if we had a PLL...
So this patch clamps the divider to 1.

The emac needs constant and very specific rate but the possible PLL-sources
are very limited, so we expect the PLL source to be set manually on per
board and don't want it to get changed in an automatic way later.
So add the necessary clock-id and disable reparenting on set_rate calls.
