[PATCH REGRESSION FIX] dw_dmac: make driver's endianness configurable

2012-10-14 Thread Hein Tibosch
From: Hein Tibosch The dw_dmac was originally developed for avr32 to be used with the Synopsys DesignWare AHB DMA controller. Starting from 2.6.38, access to the device's i/o memory was done with the little-endian readl/writel functions(1) This broke the driver for the avr32 platform, because it
