The existing implementation which encodes the configuration as a binary blob in platform data is unsatisfactory since it requires a kernel recompile for the configuration to be changed, and it doesn't deal well with firmware changes that move values around on the chip. Atmel define an ASCII format for the configuration which can be exported from their tools. This patch implements a parser for that format which loads the configuration via the firmware loader and sends it to the MXT chip.
