Laurent Pinchart be6893e195 dmaengine: rcar-dmac: Disable channel 0 when using IOMMU ... A still unconfirmed hardware bug prevents the IPMMU microTLB 0 to be flushed correctly, resulting in memory corruption. DMAC 0 channel 0 is connected to microTLB 0 on currently supported platforms, so we can't use it with the IPMMU. As the IOMMU API operates at the device level we can't disable it selectively, so ignore channel 0 for now if the device is part of an IOMMU group.
