[PATCH] DMA: Fix allocation size for PL330 data buffer depth.

2014-11-06 Thread Liviu Dudau
The datasheet for PL330 says that the data buffer value in the CRD register is 10bits wide. However, the value stored is "minus one", which the driver corrects for. Maximum value that the data buffer depth can have is 1024 lines, which requires 11 bits for storage. While making updates I found pri
