2015-01-19ARM: mvebu: use arm_coherent_dma_ops and re-enable hardware I/O coherencyThomas Petazzoni
Now that we have enabled automatic I/O synchronization barriers, we no longer need any explicit barriers. We can therefore simplify arch/arm/mach-mvebu/coherency.c by using the existing arm_coherent_dma_ops instead of our custom mvebu_hwcc_dma_ops, and re-enable hardware I/O coherency support.

2015-01-19ARM: qcom: scm: Add logging of actual return code from scm callOlav Haugan
When an error occurs during an scm call the error returned is remapped so we lose the original error code. This means that when an error occurs we have no idea what actually failed within the secure environment. Add a logging statement that will log the actual error code from scm call allowing us to easily determine what caused the error to occur.

2015-01-19ARM: qcom: scm: Flush the command buffer only instead of the entire cacheVikram Mulukutla
scm_call flushes the entire cache before calling into the secure world. This is both a performance penalty as well as insufficient on SMP systems where the CPUs possess a write-back L1 cache. Flush only the command and response buffers instead, moving the responsibility of flushing any other cached buffer (being passed to the secure world) to callers.

2015-01-19ARM: qcom: scm: Fix incorrect cache invalidationStephen Boyd
The cache invalidation in scm_call() correctly rounds down the start address to invalidate the beginning of the cacheline but doesn't properly round up the 'end' address to make it aligned. The last chunk of the buffer won't be invalidated when 'end' is not cacheline size aligned so make sure to invalidate the last few bytes in such situations. It also doesn't do anything about outer caches so make sure to invalidate and flush those as well. Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: Kumar Gala <galak@codeaurora.org>

2015-01-17ARM: mvebu: completely disable hardware I/O coherencyThomas Petazzoni
The current hardware I/O coherency is known to cause problems with DMA coherent buffers, as it still requires explicit I/O synchronization barriers, which is not compatible with the semantics expected by the Linux DMA coherent buffers API. So, in order to have enough time to validate a new solution based on automatic I/O synchronization barriers, this commit disables hardware I/O coherency entirely. Future patches will re-enable it.

2015-01-16ARM: shmobile: R-Mobile: Special-case PM domains with memory-controllersGeert Uytterhoeven
Add a special case for PM domains containing a memory-controller. Such a PM domain must not be turned off if memory is in use. On sh73a0 PM domains A4BC0 and A4BC1 each contain an SDRAM Bus State Controller (SBSC). On r8a73a4 PM domain A3BC contains two DDR Bus Controllers (DBSC). In both cases, there are no other devices in these PM domains, so they were eligible for power down, crashing the system. On r8a7740 the DDR3 Bus State Controller (DBSC3) is located in A4S, whose child domain A3SM contains the CPU core. Hence A4S is never turned off, and no crash happened.
