* driver: replace dev_request_mem_region with dev_request_mem_resourceSascha Hauer2016-03-071-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dev_request_mem_region doesn't work properly one some SoCs on which PTR_ERR() values clash with valid return values from dev_request_mem_region. Replace them with dev_request_mem_resource where possible.

* ARM: move DMA alloc functions to dma.hLucas Stach2015-03-061-1/+0
| | | | | | | | | | 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>

* mxs_spi: unbreak driverEric Bénard2013-09-101-0/+1
| | | | | | | | | | | | since the switch to common clock, SPI driver reports : MXS: Timeout resetting block via register 0x80014000 mxs_spi mxs_spi2: MXS SPI: Timeout waiting for start The reason is that the clock is not enabled anywhere in the driver.

* ARM: MXS: introduce stmp device supportSascha Hauer2013-07-231-13/+14
| | | | | | | | | | | | MXS specific devices have some common infrastructure in the kernel known as STMP devices. We have the same in barebox, but with a mxs_ prefix instead of a stmp_ prefix. As some STMP devices are also found on i.MX6 move the common infrastructure out of MXS specific files and use the stmp_ prefix. This is done in preparation for i.MX6 NAND support.
