Since the DW eDMA core now supports eDMA controllers embedded in locally
accessible DW PCIe Root Ports and Endpoints, register these controllers
when possible.
To do that the DW PCIe core driver needs to perform some preparations
first. First of all, it needs to find the eDMA controller CSRs base
address, whether they are accessible over the Port Logic or iATU unrolled
space. Afterwards it can try to auto-detect the eDMA controller
availability and number of read/write channels. If none are found the
procedure silently returns without error.
Secondly, the platform is supposed to provide either combined or
per-channel IRQ signals. If no valid IRQs set is found, the procedure
returns without error to be backward compatible with platforms where DW
PCIe controllers have eDMA but lack the IRQ description.
Finally, before actually probing the eDMA device we need to allocate LLP
items buffers. After that the DW eDMA can be registered. If registration is
successful, a message regarding the number of detected Read/Write eDMA
channels will be printed to the system as is done for the iATU settings.
Note: the DW PCI controller driver (either host or endpoint mode) is
currently always built-in, so if the DW eDMA core is built as a module
(CONFIG_DW_EDMA=m), eDMA controllers will not be registered even if the
dw-edma module is later loaded.

The DW PCIe Root Port IP core is synthesized with the 64-bit AXI address
bus. Since the device is also equipped with the eDMA engine, explicitly
set the device DMA mask so DMA engine clients can allocate data buffers
anywhere in the 64-bit memory space.

The MSI target address must be in the lowest 4GB memory to support PCI
peripherals without 64-bit MSI support. Since the allocation is done from
DMA coherent memory, set only the coherent DMA mask, leaving the streaming
DMA mask alone.
Thus streaming DMA operations will work with no artificial limitations. It
will be specifically useful for the eDMA-capable controllers so the
corresponding DMA engine clients would map the DMA buffers with no need for
SWIOTLB for buffers allocated above 4GB.
Add a brief comment about the reason allocating the MSI target address
below 4GB.

Kconfig "select" is discouraged for visible symbols like DW_EDMA because it
makes it possible to set DW_EDMA even if DW_EDMA depends on things that are
not set (see Documentation/kbuild/kconfig-language.txt).
Convert DW_EDMA_PCIE so it depends on DW_EDMA instead of selecting it.
There will likely be several future drivers that depend on DW_EDMA, so this
uses "if DW_EDMA" to enclose them all rather than repeating "depends on
DW_EDMA" for each.

Currently the DW eDMA driver only supports the linked lists memory
allocated locally with respect to the remote eDMA engine setup. It means
the linked lists will be accessible by the CPU via the MMIO space only. If
eDMA is embedded into the DW PCIe Root Ports or local Endpoints (which
support will be added in subsequent commits) the linked lists are supposed
to be allocated in the CPU memory. In that case the LL-entries can be
directly accessed, while the former case implies using the MMIO accessors
for that.
In order to have both cases supported by the driver, the dw_edma_region
descriptor should be fixed to contain the MMIO-backed and just memory-based
virtual addresses. The linked lists initialization procedure will use one
of them depending on the eDMA device nature. If the eDMA engine is embedded
into the local DW PCIe Root Port/Endpoint controllers, the list entries
will be directly accessed by referencing the corresponding structure
fields. Otherwise the MMIO accessors usage will be preserved.

A recent commit moved enabling of runtime PM from adreno_gpu_init() to
adreno_load_gpu() (called on first open()), which means that unbind()
may now be called with runtime PM disabled in case the device was never
opened in between.
Make sure to only forcibly suspend and disable runtime PM at unbind() in
case runtime PM has been enabled to prevent a disable count imbalance.
This specifically avoids leaving runtime PM disabled when the device
is later opened after a successful bind:

If, for whatever reason, we're trying process adreno_runtime_resume()
at the same time that a6xx_destroy() is running then things can go
boom. Specifically adreno_runtime_resume() will eventually call
a6xx_pm_resume() and that may try to resume the gmu.
Let's grab the GMU lock as we're destroying the GMU. That will solve
the race because a6xx_pm_resume() grabs the same lock. That makes the
access of `gmu->initialized` in a6xx_gmu_resume() safe.
We'll also return an error code in a6xx_gmu_resume() if we see that
`gmu->initialized` was false. If this happens we'll bail out of the
rest of a6xx_pm_resume(), which is good because the rest of that
function is also not good to do if we're racing with a6xx_destroy().

- improvements in the gpio-regmap library
- add helper for GPIO device reference counting
- remove unused APIs
- minor tweaks like sorting headers alphabetically

- add support for Tegra 234 PMC to gpio-tegra186
Driver improvements:
- migrate the 104-dio/idi family of drivers to using the regmap-irq
API
- migrate gpio-i8255 and gpio-mm to the GPIO regmap API
- clean-ups in gpio-pca953x
- remove duplicate assignments of of_gpio_n_cells in gpio-davinci,

- fix OF-related header includes and Kconfig dependencies in
gpio-zevio
- dynamically allocate the GPIO base in gpio-omap

"This has been a fairly quiet release for SPI, though it is likely that
the next release will have some big changes as there's some
preparatory work for multiple chip select support gone in - the rest
of the code is on the list but will need to be rebased onto -rc1.
Otherwise there's a couple of new tunables for chip select timings,
some new devices and smaller device specific updates and fixes.
- Support for configuring the hold and minimum inactive times for
chip selects.
- Beginnings of support for supporting devices which have multiple
chip selects on a single device.
- Support for newer Broadcom HSSPI and Intel controllers, Silicon
Labs EM3581 and SI3210"

Most but not all PWMs drive the PWM pin to its inactive state when
disabled. However if there is no enable_gpio and no regulator the PWM
must drive the inactive state to actually disable the backlight.
So keep the PWM on in this case.
Note that to determine if there is a regulator some effort is required
because it might happen that there isn't actually one but the regulator
core gave us a dummy. (A nice side effect is that this makes the
regulator actually optional even on fully constrained systems.)
This fixes backlight disabling e.g. on i.MX6 when an inverted PWM is
used.
Hint for the future: If this change results in a regression, the bug is
in the lowlevel PWM driver.

When the function pwm_backlight_update_status() was called with
brightness > 0, pwm_get_state() was called twice (once directly and once
in compute_duty_cycle). Also pwm_apply_state() was called twice (once in
pwm_backlight_power_on() and once directly).
Optimize this to do both calls only once.
Note that with this affects the order of regulator and PWM setup. It's
not expected to have a relevant effect on hardware. The rationale for
this is that the regulator (and the GPIO) are reasonable to switch in
pwm_backlight_power_on()/pwm_backlight_power_off() but the PWM has
nothing to do with power. (The post_pwm_on_delay and pwm_off_delay are
still there though.)
