This patch series enables DMA for QSPI on dra7xx and am43xx. Patch 1 and 2 make sure the buffers are mem aligned for dma operation. Patch 3-6 add support for enabling and disabling of edma3 clocks on am43xx and dra7xx. Patch 7-9 add dma functionality to ti_qspi driver. Patch 10-11 enable edma3 support on dra7xx and am43xx in respective config files.
