2010-09-07omap4: pm: Mask Secure interrupt which gate lowpower statesSantosh Shilimkar
This patch masks the Secure interrupt at wakeupgen level. This interrupt is controlled only from secure SW and non-secure SW should be immune to it. Additinaly the L3 error interupts are masked since they are gating the lowpower states. This hack will be removed once the L3 error-handling is in place Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com>
2010-09-07omap4: pm: Fix the cpuidle barriers and restore CPUx stateSantosh Shilimkar
This patch fixes two issues. 1. Barriers in the cpudile path 2. Restoration of CPUx state, to avoid accidental transitions of CPUx power domain to low power states while executing WFI outside the idle thread. Secure software and hotplog path are examples of this problems Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com>
2010-09-07omap4: pm-debug: Fix the pwrdomain clockdomain countersSantosh Shilimkar
This patch fixes the lopw power powerdomain, clockdomain counters One can mount the debug fs and check the low-power state e.g $cat /proc/sys/debug/pm_debug/count | grep mpu $mpu_pwrdm (ON),OFF:87186,RET:2605909,INA:0,ON:2693096,RET-LOGIC-OFF:2605909 Additionaly MPU OFF is programmed to OFF instead of RET in suspend path Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com>

2010-09-01OMAP4: PandaBoard: add board revision reportingDavid Anders
Add initial support for determining the board revision of the PandaBoard and reports the version on boot. This will assist in determining which board is being used when providing techincal support. The board revision will also be used to determine which GPIO and other configuration changes are needed between different hardware revisions of the PandaBoard.

2010-09-01OMAP4:DSS:HDMI: don't handle DISCONNECT if we've already got a CONNECTRob Clark
(renamed from: RFC: don't handle DISCONNECT if we've already got a CONNECT) Change the irq status to be a bitmask, so multiple irq's can be handled at one time in work-queue function. This avoids handling a disconnect if a connect already comes by the time the work queue function runs. Also, avoid powering off PHY/PLL to avoid getting inconsistant connect/disconnect interrupts and inconsistant HPD status. Signed-off-by: Rob Clark <rob@ti.com>

2010-08-27ARM: stack protector: change the canary value per taskBryan Wu
A new random value for the canary is stored in the task struct whenever a new task is forked. This is meant to allow for different canary values per task. On ARM, GCC expects the canary value to be found in a global variable called __stack_chk_guard. So this variable has to be updated with the value stored in the task struct whenever a task switch occurs. Because the variable GCC expects is global, this cannot work on SMP unfortunately. So, on SMP, the same initial canary value is kept throughout, making this feature a bit less effective although it is still useful. One way to overcome this GCC limitation would be to locate the __stack_chk_guard variable into a memory page of its own for each CPU, and then use TLB locking to have each CPU see its own page at the same virtual address for each of them.

2010-08-26OMAP4:DSS: add generic notifier mechanismRob Clark
A callback can be registered by the dssdev client in order to be notified of resolution changes, for example an external monitor that is hot-plugged. Multiple clients can now register for notification from one dssdev, and the notification mechanism can be extended in the future to add other events. Note that this patch supersedes the "OMAP4:DSS: add callback to notify client of resolution change" patch. Signed-off-by: Rob Clark <rob@ti.com>
2010-08-26OMAP4:DSS:HDMI: cleanup hdmi specific sysfs filesRob Clark

2010-08-26omap:iodmm-fixes to unmap and general cleanupHari Kanigeri
Following fixes are handled by this patch. - Unmapping of buffers - Pages were allocated on 1K boundary instead of 4K - Use VM_IO to detect IO buffers (eg: Tiler) - Page_cache_release calls were missing for unmapping part. - find_containing_mapping function is extended to check based on da address as well. This is needed during unmap part - Cleanup of unused header files in iodmm.c - Cleanup of unused case to clear PTE entries. PTE entries would get cleaned during device release - Added function headers with description - Uncommented omap_delete_vmm_pool code. This patch still has a hack code to handle Tiler buffer. Tiler buffer should be handle dby VM_IO itself and doesn't need to depend on flags. Signed-off-by: Hari Kanigeri <h-kanigeri2@ti.com>
2010-08-26omap:iommu-load cam register before flushing the entryHari Kanigeri
The flush_iotlb_page is not loading the cam register before flushing the cam entry. This causes wrong entry to be flushed out from the TLB, and if the entry happens to be a locked TLB entry it would lead to MMU faults. The fix is to load the cam register with the address to be flushed before flushing the TLB entry. Signed-off-by: Hari Kanigeri <h-kanigeri2@ti.com>
