So, again against latest pxa-linux-2.6/devel, with the following
changes:

 * Move to __raw_readl/__raw_writel for FPGA/CPLD register access
 * Change Toppoly LCD config to be selectable at run time rather than
   compile time.
 * Remove currently unused irq device suspend/resume functions.
 * Strip out unnecessary/duplicated #includes.
 * Some code style cleanups.
