* param: make parameter functions more consistentSascha Hauer2017-04-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | This patch creates a consitent set of device parameter functions. With this we have: dev_add_param_<type><access> "type" is one of: int32, uint32, int64, uint64, string, mac, ipv4, enum, bitmask The improvement here is that we now can exactly specify the width of the int type parameters and also correctly distinguish between signed and unsigned variables which means that a variable no longer ends up with INT_MAX when it's assigned -1. "access" can be empty for regular read/write parameter, "_ro" for readonly parameters which get their value from a variable pointer in the background or "_fixed" for parameters which are set to a fixed value (without a pointer in the background). Some more exotic types are not (yet) implemented, like dev_add_param_ip_ro. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* driver: replace dev_request_mem_region with dev_request_mem_resourceSascha Hauer2016-03-071-3/+5

* rework remap_rangeSascha Hauer2015-11-031-3/+2
| | | | | | | | | | | | | | | | | | remap_range is for remapping regions with different cache attributes. It is implemented for ARM and PowerPC only, the other architectures only provide stubs. Currently the new cache attributes are passed in an architecture specific way and the attributes have to be retrieved by calls to mmu_get_pte_cached_flags() and mmu_get_pte_uncached_flags(). Make this simpler by providing architecture independent flags which can be directly passed to remap_range() Also provide a MAP_ARCH_DEFAULT flag and a arch_can_remap() function. The MAP_ARCH_DEFAULT defaults to whatever caching type the architecture has as default. the arch_can_remap() function returns true if the architecture can change the cache attributes, false otherwise. This allows the memtest code to better find out what it has to do. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

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

* ARM: change dma_alloc/free_coherent to match other architecturesLucas Stach2015-03-061-1/+2
