Update the Lager DTS to make use of the new unified legacy
memory map where the legacy window on Lager and Koelsch
have the same size.
With this change in place the code gets aligned with the
documentation.
After update the Lager board has the following map:
Bank0: 1GiB RAM (Legacy 32-bit: 0x40000000->0x7fffffff)
Bank1: 3GiB RAM (LPAE area: 0x140000000->0x1ffffffff)
Before the update the old map looked like this:
Bank0: 2GiB RAM (Legacy 32-bit: 0x40000000->0xbfffffff)
Bank1: 2GiB RAM (LPAE area: 0x180000000->0x1ffffffff)

Add needed information inside CPU0 for the generic cpufreq-cpu0 driver.
- voltage-tolerance = 1%
It reflects the tolerance for the CPU voltage defined inside the OPP
table. Due to the lack of proper OPP definition, use an arbitrary safe
value.
- clock-latency = 300 us
Approximate worst-case latency to do a full DVFS transition for every
OPPs. Due to the lack of HW information, use an arbitrary safe value.
Note: The term transition-latency will be more accurate to define this
value since the clock transition latency is not the only parameter that
will define the overall DVFS transition.
- operating-points = < kHz - uV >
List of 6 operating points. All of them are using the same voltage
since DVS is not supported in R-CAR Gen2.

The majority of these changes are cleanups and fixes across all drivers.
Redundant error messages are removed and more PWM controllers set the
.can_sleep flag to signal that they can't be used in atomic context.
Support is added for the Broadcom Kona family of SoCs and the Intel LPSS
driver can now probe PCI devices in addition to ACPI devices. Upon shut-
down, the pwm-backlight driver will now power off the backlight. It also
uses the new descriptor-based GPIO API for more concise GPIO handling.
A large chunk of these changes also converts platforms to use the lookup
mechanism rather than relying on the global number space to reference
PWM devices. This is largely in preparation for more unification and
cleanups in future patches. Eventually it will allow the legacy PWM API
to be removed.

This is a small follow-up to the larger ARM SoC updates merged

The main change here is to use the new dma-ranges parsing code
that came in through Russell's ARM tree. This allows the keystone
platform to do cache-coherent DMA and to finally support all the
available physical memory when LPAE is enabled.
Aside from this, the keystone reset driver has been rewritten,
and there is a small bug fix to allow building the orion5x platform
again.

Patch to prevent warning of a buggy compiler when using clang and
the ARM_UNWIND option.
Clang defines (at least on the current trunk) GNUC, GNUC_MINOR, and
GNUC_PATCHLEVEL to 4, 2, and 1 respectively.
This version of GCC gets flagged as buggy, but it isn't actually an
issue with clang so the patch will do what it did before unless clang
is defined and then it will not report the GCC version as an issue.

With compilers which follow the C99 standard (like modern versions of gcc and
clang), "extern inline" does the wrong thing (emits code for an externally
linkable version of the inline function). "static inline" is the correct choice
instead.

Duty Cycle Correction(DCC) needs to be enabled if the MPU is to run at
frequencies beyond 1.4GHz for OMAP5, DRA75x, DRA72x.
MPU DPLL has a limitation on the maximum frequency it can be locked
at. Duty Cycle Correction circuit is used to recover a correct duty
cycle for achieving higher frequencies (hardware internally switches
output to M3 output(CLKOUTHIF) from M2 output (CLKOUT)).
For further information, See the note on OMAP5432 Technical Reference
Manual(SWPU282U) chapter 3.6.3.3.1 "DPLLs Output Clocks Parameters",
and also the "OMAP543x ES2.0 DM Operating Conditions Addendum v0.5"

present in relevant DRA75x, 72x documentation(SPRUHP2E, SPRUHI2P).
