This series add DMA support for reading data from HyperBus memory
devices for TI's AM654/J721e SoCs

With DMA there is ~5x improvement in read througput.

Vignesh Raghavendra (4):
  mtd: hyperbus: Provide per device private pointer
  mtd: hyperbus: hbmc-am654: Fix direct mapping setup flash access
  mtd: hyperbus: hbmc-am654: Drop pm_runtime* calls from probe
  mtd: hyperbus: hbmc-am654: Add DMA support for reads
