Merge branch '4.15-rc1-clkctrl-mach-omap2' of https://github.com/t-kristo/linux-pm into omap-for-v4.16/soc

Make these const as they are only getting passed to the functions
cm_register and cm_unregister having the arguments as const.

Make the pointer cm_ll_data of type cm_ll_data as const as it does not
modify the fields of the structure it points too.
After this change, make the argument of cm_register function as const as
it is used to initialise cm_ll_data or used inside an if condition.
Make the pointer argument of cm_unregister function as const as it is only
used inside an if condition.
Add const to the function prototypes too.

"default_sata_clkdm" does not exist, instead replace this with the
correct clockdomain name which is just "default_clkdm".

Add support for the address translation logic for am33xx. Needed for
mapping hwmods towards their corresponding clkctrl providers and clocks.

There are cases where clkctrl clock offsets do not match the corresponding
clockdomain, and this case the existing mapping functionality will fail.
Fix this by adding the whole address range for a clkctrl provider and
matching the actual clkctrl registers against these ranges.

Needed to map clkctrl clocks against hwmods. This patch also removes
the obsolete clkdm_xlate_address function which is no longer needed
for anything.

Add a new CM API for fetching the physical address of a hwmod clkctrl
register. This is needed to map omap hwmods against clkctrl clocks, the
existing support for clkdm address translation was not sufficient to
handle the mutant cases where the clockdomain offset is completely
off from the clkctrl ones.

Re-route all opt-clocks to use the new clkctrl clocks also, instead of
depending on the old dt clocks. Also, add aliases for certain clkctrl
clocks that hwmod core depends upon. The alias list can be stripped
down once hwmod database no longer needs these.

In case the clkctrl node contains assigned-clock-* entries, registering

In certain cases it is possible that the timekeeping has been suspended
already when attempting to disable/enable a clkctrl clock. This will
happen at least on am43xx platform when attempting to enable / disable
the clockevent source itself, burping out a warning from timekeeping core.

The sequence of events leading to this:
-> timekeeping_suspend()
 -> clockevents_suspend()
  -> omap_clkevt_idle()
   -> omap_hwmod_idle()
    -> _omap4_clkctrl_clk_disable()
     -> _omap4_is_timeout()

Avoid the issue by checking if the timekeeping is suspended and using
the fallback udelay approach for checking timeouts.

hwmod core still depends on certain clocks being found by name, so we

be reverted when no longer needed by hwmod core code.

Current node name does not convey any information, as it is always "clk".
Instead, print out the full node path, which will tell us better where
something went wrong.
