* driver: replace dev_request_mem_region with dev_request_mem_resourceSascha Hauer2016-03-071-3/+5

Replace them with dev_request_mem_resource where possible.

| | | | | | | The set_ethaddr callback should not modify the MAC address passed to it, so make it const. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | Move to the common streaming DMA ops in order to get rid of the direct usage of the ARM MMU functions for the cache maintenance. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * ARM: move DMA alloc functions to dma.hLucas Stach2015-03-061-0/+1
| | | | | | | | | | | | | | | | | | | | This better separates the DMA from the MMU functionality. Also move all drivers that only depends on asm/mmu.h for the alloc functions over to the common header. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * ARM: change dma_alloc/free_coherent to match other architecturesLucas Stach2015-03-061-2/+4
| | | | | | | | | | | | | | | | | | As a lot drivers currently rely on the 1:1 virt->phys mapping on ARM we define DMA_ADDRESS_BROKEN to mark them. In order to use them on other architectures with a different mapping they need proper fixing. Signed-off-by: Lucas Stach <dev@lynxeye.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
