Hi, R-Car Gen2 have two DMA controllers, which are equivalent. However DMA slaves were tied only to a single DMA controller in .dtsi. This series add references to to both DMA controllers for all nodes that previously only referenced one of them. It also adds dma references to the SDHI nodes for r8a7794 which according to the datasheet should work but I have not access to HW to verify. Tested on Koelsch (r8a7791) by altering the compatible value of either dmac0 or dmac1 and verifying that the DMA slaves pick the DMA controller that is instantiated. For your convince the series can be fetched from https://git.ragnatech.se/linux rcar-dmas-dt-2 * Changes since v1 - Rebase on top of renesas-devel-20160315-v4.5 and add dmas references new nodes (r8a7790: scif2 r8a7793: i2c6,i2c7,i2c8). - Correct error in commit message 31/31 (s/QSPI/MMCIF). - Collect Ack and Reviewed tags from Geert.
