[PATCH v2 0/2] mmc: atmel-mci: repair driver for use with AVR32 (AP7000)

Due to changes after 2.6.38, the drivers atmel-mci and dw_dmac got broken for the AVR32 platform: the AP7000. These two patches repair the atmel-mci driver Thanks to Ludovic and Hans-Christian for their comments Hein Tibosch (2): mmc: atmel-mci: DMA can be used with other controller mmc

[PATCH v2 1/2] mmc: atmel-mci: DMA can be used with other controller

s can be used with a different controller than the Atmel AHB DMA one. For instance, some AVR chips use the Synopsys DesignWare AHB DMA controller. v2: in atmci_configure_dma: check both pdata and pdata->dma_slave Signed-off-by: Hein Tibosch Acked-by: Ludovic Desroches --- drivers/mmc/ho
