This patch adds the module parameter "delaydivider" to set delay for the
deferred io. Effectively this is setting the refresh rate for mmap access
to the framebuffer. The delay for the deferred io is HZ/delaydivider.

This patches unifies the init code for the ssd130X chips and
adds device tree bindings to describe the hardware configuration
of the used controller. This gets rid of the magic bit values
used in the init code so far.

This patch adds a module parameter 'bitsperpixel' to adjust the colordepth
of the framebuffer. All values >1 will result in memory map of the requested
color depth. However only the MSB of each pixel will be sent to the device.

This patch series is the result of making the ssd1307fb driver work with
a Newhaven OLED display using the Solomon SSD1305 controller. To achieve
this the intialization code for the SSD1306 and the SSD1307 is merged

This patch adds sysfs handles to enable userspace control over the display
contrast as well as the dim mode. The handles are available as "contrast"
and "dim" in the framebuffers sysfs domain.

It makes sense to use vmalloc to allocate the video buffer since it has to be
page aligned memory for using it with
mmap. Also deffered io seems buggy in combination with kmalloc'ed memory (crash
on unloading the module).
