[PATCH v2] ARM: edma: fix residue race for cyclic

2015-10-16 Thread John Ogness
When retrieving the residue value for cyclic transfers, the SRC/DST fields of the active PaRAM are read. However, the AM335x Technical Reference Manual states: 11.3.3.6 Parameter Set Updates After the TR is read from the PaRAM (and is in the process of being submitted to the EDMA3TC), the f
