The MSIOF Base Address for DMAC was removed only from the R-Car Gen2/Gen3
manuals. It still affects e.g. R-Mobile APE6.
Do we have a nice run time detection for that?
The current driver code just looks at the DTS, cfr. the comment:
/* The DMA engine uses the second register set, if present */
Ok, yes, thanks.
So this patch is completely superfluous, even in the BSP, correct?
Will drop it for the next round, hoping that it doesn't result in too
much rebase hassle ;)
Best regards
Dirk
