Staging driver fixes for 4.3-rc3
Here are some tiny staging driver and documentation fixes for 4.3-rc3. All of these resolve reported issues that people have found and have been in the linux-next tree for a while with no problems.

|

- add proper arch dependencies as needed
|
||||
- audit userspace interfaces to make sure they are sane
|
||||
|
||||
|
||||
ion/
|
||||
- Remove ION_IOC_SYNC: Flushing for devices should be purely a kernel internal
|
||||
interface on top of dma-buf. flush_for_device needs to be added to dma-buf
|
||||
first.
|
||||
- Remove ION_IOC_CUSTOM: Atm used for cache flushing for cpu access in some
|
||||
vendor trees. Should be replaced with an ioctl on the dma-buf to expose the
|
||||
begin/end_cpu_access hooks to userspace.
|
||||
- Clarify the tricks ion plays with explicitly managing coherency behind the
|
||||
dma api's back (this is absolutely needed for high-perf gpu drivers): Add an
|
||||
explicit coherency management mode to flush_for_device to be used by drivers
|
||||
which want to manage caches themselves and which indicates whether cpu caches
|
||||
need flushing.
|
||||
- With those removed there's probably no use for ION_IOC_IMPORT anymore either
|
||||
since ion would just be the central allocator for shared buffers.
|
||||
- Add dt-binding to expose cma regions as ion heaps, with the rule that any
|
||||
such cma regions must already be used by some device for dma. I.e. ion only
|
||||
exposes existing cma regions and doesn't reserve unecessarily memory when
|
||||
booting a system which doesn't use ion.
