2011-10-25OMAP2+: mailbox: fix lookups for multiple mailboxesSebastien Jan
Re-apply the following patch. It was partially reverted by a merge with mutex addition. This fix is required because, as expected, the concerned code generates an error with gcc4.6 (but not with gcc4.5!). OMAP2+: mailbox: fix lookups for multiple mailboxes The pointer math in omap_mbox_get() is not quite right, and leads to passing NULL to strcmp() when searching for an mbox that is not first in the list. Convert to using array indexing as is done in all the other functions which walk the mbox list. Tested on OMAP2420/n810, OMAP3630/zoom3, OMAP4430/Blaze Signed-off-by: Kevin Hilman <khilman@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com> Conflicts: arch/arm/plat-omap/mailbox.c Signed-off-by: Sebastien Jan <s-jan@ti.com>

2011-10-25ARM: cache-l2x0: update workaround for PL310 errata 727915Colin Cross
ARM errata 727915 for PL310 has been updated to include a new workaround required for PL310 r2p0 for l2x0_flush_all, which also affects l2x0_clean_all in my testing. For r2p0, clean or flush each set/way individually. For r3p0 or greater, use the debug register for cleaning and flushing. Requires exporting the cache_id, sets and ways detected in the init function for later use. Change-Id: I215055cbe5dc7e4e8184fb2befc4aff672ef0a12 Signed-off-by: Colin Cross <ccross@android.com>

2011-10-25omap4: remoteproc: return proper status for status and stopSuman Anna
The return status for the userspace ProcMgr_start and ProcMgr_stop API is not returned properly. This causes the user-space to ignore and proceed with the IPC synchronization sequence even if the processor has not been put into a proper device state (asserting or deasserting Reset).

2011-10-25syslink: iommu: provide new api to return a deviceBryan Honza
The ipu device is missing from the omap_ipupm_data. This results in a null device pointer being used when applying constraints. This change provides an api which can be used to return a device when queried by name. This is to support initializing omap_ipupm_data with a device.

2011-10-25syslink: notify: process both cores ipc stack for each mailbox interruptSubin K G
For each mailbox interrupt,process both cores(sysm3 and appm3) ipc stack. This is to fix the issue of message being dropped, when both cores tries to put the message at the same time. For example both sysm3 and appm3 are trying to write into MBX and appm3 sees that there is already a message pending by SYSM3.In this case appm3 will not interrupt A9.But A9 will only process sysm3 ipc stack.So to take care of this,process both cores ipc stack for each MBX interrupt.

2011-10-25syslink: ipc: limit the retry count for ipc attachSubin K G
Currenlty ipc_attach is whiling inside the kernel till it become success.This has been changed to a retry for 500ms, after that it will report failure to userspace. This change is to avoid rebooting of the board, in case if ipc_attach fails. Change-Id: Ie47043c54858140e198af7354b9441232a117760 Signed-off-by: Subin K G <subin.kg@ti.com>
2011-10-25omap: remoteproc: return rproc status instead of omap device statusJuan Gutierrez
rproc_get_state was returning omap_device status instead of the current rproc status. This mismatch was leading to some unhandled states like when the remote proc is hibernated. This was causing users-space registration for PROC_START events to timeout, due to the mismatch states.

2011-10-25syslink: procmgr: initialize is_cached parameter before unmapBryan Honza
The is_cached parameter is not initialized prior to calling platform_mem_unmap from proc4430_detach. This change sets the is_cached parameter to false to match the value used when mapped so that the memory entries are now unmapped consistently.

2011-10-25syslink: procmgr: initialize attach_countBryan Honza
atomic_cmpmask_and_set() is operating on an uninitialized attach_count which can pass the cmpmask as if it has been initialized resulting in the cmpmask_and_set() not initializing the attach_count. For instance, if the uninitialized attach_count happens to be 0xffffffff, atomic_cmpmask_and_set() will not change the attach_count. This attach_count is allocated on the heap.

2011-10-25omap4: iommu: add pm constraints for ducati iommuSuman Anna
A constraint for CORE domain is requested by the IOMMU driver before releasing the Ducati's RST3, and is released when the IOMMU is being disabled. This ensures that the CORE domain does not go into Retention after releasing RST3, thereby eliminating any context loss in the Ducati Unicache registers due to CORE domain OSWR transitions. For runtime PM, the constraint is relaxed after the IOMMU driver has saved its context when Ducati is either self-hibernating or being suspended, and the constraint is requested again before restoring the context for ducati resume.

2011-10-25syslink: ipu_pm: fix ret in idle path after recoveryMiguel Vadillo
After recovery the mechanism to release all the resources and constraints was not taking in to consideration the IPU that is created behind the scenes to handle the sys and app constraints and as a consequence all the constraints attached to it were not released leading to not hit retention in idle path. That IPU behind scenes is a special rcb slot that only has constraints; the fix is taking care of this case and releases only the constraints. If the IPU is explicitly requested then it will be consider as a normal resource.
