3 * DMA support for Internal DMAC with SDHI SD/SDIO controller
69 * - Since this SDHI DMAC register set has 16 but 32-bit width, we
75 * Workaround for avoiding to use RX DMAC by multiple channels.
77 * RX DMAC simultaneously, sometimes hundreds of bytes data are not
78 * stored into the system memory even if the DMAC interrupt happened.
79 * So, this driver then uses one RX DMAC channel only.
