ARM: arm-soc fixes for 3.8-rc
People are back from the holiday breaks, and it shows. Here are a bunch of
fixes for a number of platforms:
- A couple of small fixes for Nomadik
- A larger set of changes for kirkwood/mvebu
- uart driver selection, dt clocks, gpio-poweroff fixups,
a few __init annotation fixes and some error handling improvement
in their xor dma driver.
- i.MX had a couple of minor fixes (and a critical one for flexcan2
clock setup)
- MXS has a small board fix and a framebuffer bugfix
- A set of fixes for Samsung Exynos, fixing default bootargs and some
Exynos5440 clock issues
- A set of OMAP changes including PM fixes and a few sparse warning
fixups
All in all a bit more positive code delta than we'd ideally want to see
here, mostly from the OMAP PM changes, but nothing overly crazy.

GPIO line that should be set high/low to power off a device

Driver a GPIO line that can be used to turn the power off.
|
||||
|
||||
The driver supports both level triggered and edge triggered power off.
|
||||
At driver load time, the driver will request the given gpio line and
|
||||
install a pm_power_off handler. If the optional properties 'input' is
|
||||
not found, the GPIO line will be driven in the inactive
|
||||
state. Otherwise its configured as an input.
|
||||
|
||||
When the pm_power_off is called, the gpio is configured as an output,
|
||||
and drive active, so triggering a level triggered power off
|
||||
condition. This will also cause an inactive->active edge condition, so
|
||||
triggering positive edge triggered power off. After a delay of 100ms,
|
||||
the GPIO is set to inactive, thus causing an active->inactive edge,
|
||||
triggering negative edge triggered power off. After another 100ms
|
||||
delay the GPIO is driver active again. If the power is still on and
|
||||
the CPU still running after a 3000ms delay, a WARN_ON(1) is emitted.

||||
