Subject: [PATCH 0/2] spi: spi-omap2-mcspi: Add DMA support for AM65x

This patch series adds DMA support for McSPI on AM65x.
First patch addresses a limitationn on AM65x where transfers have to be
<4K per DMA request and second patch handles possible EPROBE_DEFER when
requesting DMA channels

  spi: spi-omap2-mcspi: Handle DMA size restriction on AM65x
  spi: spi-omap2-mcspi: Support probe deferral for DMA channels
