A software delay marker can be inserted into the command sequence, once pxafb_smart_queue() detects this, it flushes the previous commands and delay for a specified number of milliseconds.

Originally designed by Intel, now sold by Crossbow (www.xbow.com). Very little actually on board. The patch includes sensors and similar as found on commonly occurring daughter boards. Some of the drivers are not in mainline as yet as they are either part of the IIO subsystem or need a lot of work before submission. What is the position wrt to putting them in i2c board configs etc? Support for these boards has been maintained outside the kernel for a long time, but now that there is a good da9030 pmic driver available the last major hurdle no longer exists. All comments welcomed. The Imote2's big brother (stargate2) will follow once any problems with this one have been cleaned up and a few bits and bobs have been added to the da903x driver. Hopefully the cc2420 driver will get cleaned up and submitted in the not too distant future as well.
