This patch refactors the dt parsing code to avoid setting platform_data,
instead just setting lp->pdata directly. This facilitates easier
probe deferral since the current scheme would require us to clear out
dev->platform_data before deferring.

If PWM device is requested by means of legacy API pwm_request(), its

commit 257462dbf3 ("pwm-backlight: switch to gpiod interface")
introduced a regression leading to acquiring a bogus GPIO-0 when
configured from DT without an 'enable-gpios' property.
The driver will happily accept the 0 initialized 'enable_gpio' member
of the struct platform_pwm_backlight_data as valid gpio number, and
request this GPIO as enable pin. In case of multiple driver instances,
the second will fail to register with the error message:
pwm-backlight backlight1.23: failed to request GPIO#0: -16
Fix this by setting enable_gpio in the pdata struct to -EINVAL.

A handful of driver-related changes. We've had a bunch of them going in through
other branches as well, so it's only a part of what we really have this release.
Larger pieces are:
* Removal of a now unused PWM driver for atmel
- This includes AVR32 changes that have been appropriately acked.
* Performance counter support for the arm CCN interconnect
* OMAP mailbox driver cleanups and consolidation
* PCI and SATA PHY drivers for SPEAr 13xx platforms
* Redefinition (with backwards compatibility!) of PCI DT bindings for Tegra to
better model regulators/power.

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.

Some firmware drivers, ie acpi-video want to get themselves out of the
way (in some cases) when their also is a raw backlight device available.
Due to module loading ordering being unknown, acpi-video cannot be certain
that the backlight_device_registered(BACKLIGHT_RAW) it does for this is
the final verdict wrt there being a BACKLIGHT_RAW device.
By adding notification acpi-video can listen for backlight devices showing
up after it has loaded, and unregister its backlight device if desired.

There are still a couple of users of this driver that rely on passing
the enable GPIO number through platform data, so a fallback mechanism
using a GPIO number is still available to avoid breaking them. It will
be removed once current users have switched to the GPIO lookup tables
provided by the gpiod interface.

When a device is shut down, make sure to disable the backlight. If it
stays lit, it gives the impression that the device hasn't turned off.
Furthermore keeping the backlight on may consume power, which is not
what users expect when they shut down a device.

The LP8788 driver cannot be successfully built if we don't

As per the comments on device_register, we shouldn't call kfree()

We don't have to update a backlight status every time a blanking or
unblanking event comes because the backlight status may have already
been what we want. Another thought is that one backlight device may be
shared by multiple framebuffers. We don't hope blanking one of the
framebuffers may turn the backlight off for all the other framebuffers,
since they are likely being active to display something.
This patch makes the backlight status be updated only when the relevant
backlight device's use count changes from zero to one or from one to
zero.

We don't have to update the state and fb_blank properties of a backlight
device every time a blanking or unblanking event comes because they may
have already been what we want. Another thought is that one backlight
device may be shared by multiple framebuffers. The backlight driver
should take the backlight device as a resource shared by all the
associated framebuffers.
This patch adds some logic to record each framebuffer's backlight usage
to determine the backlight device use count and whether the two
properties should be updated or not. To be more specific, only one
unblank operation on a certain blanked framebuffer may increase the
backlight device's use count by one, while one blank operation on a
certain unblanked framebuffer may decrease the use count by one, because
the userspace is likely to unblank an unblanked framebuffer or blank a
blanked framebuffer.

This is wrong as the last reference is not given up with a put_device
