      i2c: Convert most new-style drivers to use module aliasing · 3760f736
      由 Jean Delvare 提交于 
      Based on earlier work by Jon Smirl and Jochen Friedrich.

Update most new-style i2c drivers to use standard module aliasing
instead of the old driver_name/type driver matching scheme. I've
left the video drivers apart (except for SoC camera drivers) as
they're a bit more diffcult to deal with, they'll have their own
patch later.

      atmel_lcdfb: don't initialize a pre-allocated framebuffer · 01d3a5e7
      由 Haavard Skinnemoen 提交于 
      If the user specified a fixed framebuffer address on the command line, it may
have been initialized already with a splash image or something, so we
shouldn't clear it.

Therefore, we should only initialize the framebuffer if we allocated it
ourselves.  This patch also updates the AVR32 setup code to clear the
framebuffer if it allocated it itself, i.e.  the user didn't provide a fixed
address or the reservation failed.

I've updated the at91 platform code as well so that it initializes the
framebuffer if it is located in SRAM, but I haven't tested that it actually
works.

      atmel_lcdfb: backlight control · a9a84c37
      由 David Brownell 提交于 
      On the sam9 EK boards, the LCD backlight is hooked up to a PWM output from
the LCD controller.  It's controlled by "contrast" registers though.

This patch lets boards declare that they have that kind of backlight
control.  The driver can then export this control, letting screenblank and
other operations actually take effect ...  reducing the typically
substantial power drain from the backlight.

Note that it's not fully cooked
  - doesn't force backlight off during system suspend
  - the "power" and "blank" events may not be done right
This should be easily added in the future.

      Suspend: Introduce begin() and end() callbacks · c697eece
      由 Rafael J. Wysocki 提交于 
      On ACPI systems the target state set by acpi_pm_set_target() is
reset by acpi_pm_finish(), but that need not be called if the
suspend fails.  All platforms that use the .set_target() global
suspend callback are affected by analogous issues.

For this reason, we need an additional global suspend callback that
will reset the target state regardless of whether or not the suspend
is successful.  Also, it is reasonable to rename the .set_target()
callback, since it will be used for a different purpose on ACPI
systems (due to ACPI 1.0x code ordering requirements).

Introduce the global suspend callback .end() to be executed at the
end of the suspend sequence and rename the .set_target() global
suspend callback to .begin().
