SNES gamepads and mice share the same type of interface so they both can be
connected to the parallel port using a simple interface. Adding mouse
support to a gamepad driver may sound funny at first, but doing so in this
case makes it possible to connect and SNES gamepads and mice at the same
time, on the same port.

EEPROM support, interrupt handling, statistics gathering, and write
combining management for x86_64.
A note regarding i2c: The Atmel EEPROM hardware we use looks like an
i2c device electrically, but is not i2c compliant at all from a
functional perspective. We tried using the kernel's i2c support to
talk to it, but failed.
Normal i2c devices have a single 7-bit or 10-bit i2c address that they
respond to. Valid 7-bit addresses range from 0x03 to 0x77. Addresses
0x00 to 0x02 and 0x78 to 0x7F are special reserved addresses
(e.g. 0x00 is the "general call" address.) The Atmel device, on the
other hand, responds to ALL addresses. It's designed to be the only
device on a given i2c bus. A given i2c device address corresponds to
the memory address within the i2c device itself.
At least one reason why the linux core i2c stuff won't work for this
is that it prohibits access to reserved addresses like 0x00, which are
really valid addresses on the Atmel devices.

The monochrome->color expansion routine that handles bitmaps which have

This is caused by a bogus bit test in slow_imageblit().
Fix.
This patch may deserve to go to the stable tree. The code has already been
well tested in little-endian machines. It's only in big-endian where there is
uncertainty and Herbert confirmed that this is the correct way to go.
It should not introduce regressions.

- Correct the suspend/resume functions so the driver compiles
(SUSPEND_POWER_DOWN/RESUME_POWER_ON no longer exist).
- Convert the driver to match the recent platform device changes.
- Replace the unsafe static struct platform_device with dynamic allocation.
- Convert the driver to the new backlight code.

Backlight class attributes are currently easy to implement incorrectly.
Moving certain handling into the backlight core prevents this whilst at the
same time makes the drivers simpler and consistent. The following changes are
included:
The brightness attribute only sets and reads the brightness variable in the
backlight_properties structure.
The power attribute only sets and reads the power variable in the
backlight_properties structure.
Any framebuffer blanking events change a variable fb_blank in the
backlight_properties structure.
The backlight driver has only two functions to implement. One function is
called when any of the above properties change (to update the backlight
brightness), the second is called to return the current backlight brightness
value. A new attribute "actual_brightness" is added to return this brightness
as determined by the driver having combined all the above factors (and any
driver/device specific factors).
Additionally, the backlight core takes care of checking the maximum brightness
is not exceeded and of turning off the backlight before device removal.
The corgi backlight driver is updated to reflect these changes.
