75462c8a87 Merge tag 'module-builtin_driver-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux
Pull module_platform_driver replacement from Paul Gortmaker:
 "Replace module_platform_driver with builtin_platform driver in non
  modules.

  We see an increasing number of non-modular drivers using
  modular_driver() type register functions.  There are several downsides
  to letting this continue unchecked:

   - The code can appear modular to a reader of the code, and they won't
     know if the code really is modular without checking the Makefile
     and Kconfig to see if compilation is governed by a bool or
     tristate.

   - Coders of drivers may be tempted to code up an __exit function that
     is never used, just in order to satisfy the required three args of
     the modular registration function.

   - Non-modular code ends up including the <module.h> which increases
     CPP overhead that they don't need.

   - It hinders us from performing better separation of the module init
     code and the generic init code.

  So here we introduce similar macros for builtin drivers.  Then we
  convert builtin drivers (controlled by a bool Kconfig) by making the
  following type of mapping:

    module_platform_driver()       --->  builtin_platform_driver()
    module_platform_driver_probe() --->  builtin_platform_driver_probe().

  The set of drivers that are converted here are just the ones that
  showed up as relying on an implicit include of <module.h> during a
  pending header cleanup.  So we convert them here vs adding an include
  of <module.h> to non-modular code to avoid compile fails.  Additonal
  conversions can be done asynchronously at any time.

  Once again, an unused module_exit function that is removed here
  appears in the diffstat as an outlier wrt all the other changes"

e35415e59f drivers/power: Convert non-modular syscon-reboot to use builtin_platform_driver
This file depends on Kconfig options all of which are a bool, so
we use the appropriate registration function, which avoids us
relying on an implicit inclusion of <module.h> which we are
doing currently.

While this currently works, we really don't want to be including
the module.h header in non-modular code, which we'd be forced
to do, pending some upcoming code relocation from init.h into
module.h.  So we fix it now by using the non-modular equivalent.

bcd56fe1aa power: reset: gpio-restart: increase priority slightly
gpio-restart uses a priority of 128 and currently most soc-level restart
mechanisms use the same - with some exceptions even using 192.
But while the soc-level restarts are provided by the soc itself,
gpio-restarts will most of the time be board-specfic and be used
when some special board condition makes the soc-level restart
only a second choice.

The problem at hand manifested itself on the rk3288-veyron devices.
While the soc-level restart can sucessfully restart all other rockchip
boards I have, the veyron devices use an external restart mechanism that
seems to not only reset the soc but also some external needed components.

With both restart handlers having priority 128 in my tests the soc-specific
variant took precedent in all cases. While it could restart the soc
sucessfully in all cases, firmware then got an issue when talking to an
external component, resulting in the device being put into recovery mode.

So, give the board-specific restart handler a slight push and move it
to priority 129 to make it more important than the generic soc-specific
restart-handler.

syscon_regmap_lookup_by_phandle() which will not lookup syscon phandles
