* omap: iommu-load cam register before flushing the entryHari Kanigeri2010-10-05
| | | | | | | | | | | | | 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.

* | ARM: 6408/1: omap: Map only available sram memorySantosh Shilimkar2010-09-25
|/ | | | | | | | | | | | | | | Currently we map 1 MB section while setting up SRAM on OMAPs Regardless of the actual memory. The physical OCM RAM available on OMAP SOCs is in order of KBs. This patch maps only available sram and cleans up some un-necessary cpu_is_xxx checks. Mapping un-available or non-accessible(secure) memory on the newer ARM processor is dangerous. Because ARM CPUs can now speculatively prefetch, we should avoid mapping any no-existing or secure memory.

This constraint is meant for use by device drivers to translate a certain device-specific performance constraint (e.g., "minimum polygons per second") to a clock rate for the driver's device, given the driver's intimate knowledge of the device hardware (e.g., device type, device hardware revision, firmware revision, etc.) From a general PM core perspective, clock rate is probably the closest general analog to "performance" that is available, but the exact mapping from a use-case-specific performance constraint to clock rate must be done by the driver. Drivers intended for upstream merging shouldn't hardcode specific clock rates in their code without basing those rates on some performance criteria requested through the driver's subsystem (ideally, from userspace). Imre Deak <imre.deak@nokia.com> described the need and use-case for this constraint, and discussed the implementation - thanks, Imre.

This allows the PM core to provide feedback to the caller if a constraint is not possible. Update the one upstream user of omap_pm_set_max_mpu_wakeup_lat() to add a compatibility wrapper, needed until the driver is changed. Update some of the documentation to conform more closely to kerneldoc style. Add an additional device parameter to omap_pm_set_max_dev_wakeup_lat() to identify the device requesting the constraint. This is so repeated calls to omap_pm_set_max_dev_wakeup_lat() with the same requesting device can override the device's previously-set constraint. Also, it allows the PM core to make a decision as to whether or not the constraint should be satisfied, based on the caller's identity. Signed-off-by: Paul Walmsley <paul@pwsan.com>

This is intended to be used by device drivers (currently, via a struct platform_data function pointer) to retrieve their corresponding device's virtual base address that the MPU should use to access the device. This is needed because the omap_hwmod code does its own ioremap(), in order to gain access to the module's OCP_SYSCONFIG register. Add omap_hwmod_get_mpu_rt_va(). omap_device_get_mpu_rt_va() calls this function to do the real work. While here, rename struct omap_hwmod._rt_va to struct omap_hwmod._mpu_rt_va, to reinforce that it refers to the MPU's register target virtual address base (as opposed to, for example, the L3's). In the future, this belongs as a function in an omap_bus, so it is not necessary to call this through a platform_data function pointer.

| | * | | OMAP: hwmod: add non-locking versions of enable and idle functionsKevin Hilman2010-07-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some hwmods may need to be idled/enabled in atomic context, so non-locking versions of these functions are required. Most users should not need these and usage of theses should be controlled to understand why access is being done in atomic context. For this reason, the non-locking functions are only exposed at the hwmod level and not at the omap-device level. The use-case that led to the need for the non-locking versions is hwmods that are enabled/idled from within the core idle/suspend path. Since interrupts are already disabled here, the mutex-based locking in hwmod can sleep and will cause potential deadlocks.

| * | | omap3 nand: cleanup virtual address usagesSukumar Ghorai2010-08-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes direct reference of gpmc address from generic nand platform code. Nand platform code now uses wrapper functions which are implemented in gpmc module. Signed-off-by: Sukumar Ghorai <s-ghorai@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

Tested on AM3517EVM and OMAP3530EVM. Signed-off-by: Stanley.Miao <stanley.miao@windriver.com> Acked-by: Kevin Hilman <khilman@deeprootsystems.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
| | * | | omap: dma: Support for prefetch in destination synchronizedtransferSamu Onkalo2010-08-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Omap DMA controller can prefetch data in advance in case of destination synchronized data transfer. This may increase performance when target HW block doesn't have fifo. Data is waiting for transfer request in DMA fifo instead of read from memory.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change adds in the necessary clocks and mux pins for UART control on omap7xx devices. I also made a change in the serial code to only try and initialize two UARTs in omap_serial_init, as these devices don't have three.
