This is an incompatible change, we need to bump the version.
Looking at pxa2xx_dma_descriptor_fetch() it looks like your change is
enough:
uint32_t desc[4];
....
s->chan[ch].descr = desc[DDADR];
s->chan[ch].src = desc[DSADR];
s->chan[ch].dest = desc[DTADR];
s->chan[ch].cmd = desc[DCMD];
i.e. we always asign from a 32bit register.
In general change is not valid.
As I don't know if this device can appear as 64bit hardware, I don't
know if the change is valid and let it to the ARM gurus.
Later, Juan.
