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