      power_supply: add scope properties to some self-powered HID devices · 73db8813
      由 Jeremy Fitzhardinge 提交于 
      The Wacom and Wiimote HID drivers register power supplies for themselves
to indicate their battery levels.  Make those power supplies device scope.

      power_supply: allow a power supply to explicitly point to powered device · 83516651
      由 Jeremy Fitzhardinge 提交于 
      If a power supply has a scope of "Device", then allow the power supply
to indicate what device it actually powers. This is represented in the
power supply's sysfs directory as a symlink named "powers", which points to
the sysfs directory of the powered device.

If the device has children, then the sub-devices are also powered by
the same power supply.

      power_supply: add SCOPE attribute to power supplies · 25a0bc2d
      由 Jeremy Fitzhardinge 提交于 
      This adds a "scope" attribute to a power_supply, which indicates how
much of the system it powers.  It appears in sysfs as "scope" or in
the uevent file as POWER_SUPPLY_SCOPE=.  There are presently three
possible values:
	Unknown - unknown power topology
	System - the power supply powers the whole system
	Device - it powers a specific device, or tree of devices

A power supply which doesn't have a "scope" attribute should be assumed to
have "System" scope.

In general, usermode should assume that loss of all System-scoped power
supplies will power off the whole system, but any single one is sufficient
to power the system.

      fsl-rio: fix compile error · e0ce42e1
      由 Liu Gang 提交于 
      The "#include <linux/module.h>" was replaced by "#include <linux/export.h>"
in the patch "powerpc: various straight conversions from module.h --> export.h".
This will cause the following compile problem:
arch/powerpc/sysdev/fsl_rio.c: In function 'fsl_rio_mcheck_exception':
arch/powerpc/sysdev/fsl_rio.c:296: error: implicit declaration of function 'search_exception_tables'.

The file fsl_rio.c needs the declaration of function "search_exception_tables"
in the header file "linux/module.h".

      The AUTO_ZRELADDR selection for ARCH_IMX_V4_V5 and ARCH_MX5 should
really be mutually exclusive to ZBOOT_ROM just like what ARCH_IMX_V6_V7
does.

      arm/imx: fix the references to ARCH_MX3 · 59198b6c
      由 Shawn Guo 提交于 
      The config symbol ARCH_MX3 has been removed by commit 'a89cf59b
arm/imx: merge i.MX3 and i.MX6', and it should not be referenced
any more.

The patch also change ARCH_MX* to SOC_IMX* for other platforms.
