|\ | | | | | | | | | | | | | | | | | | | | | | Remote branch is from Ubuntu Oneiric (tag Ubuntu-3.0.0-1215.27) with minor patch to the TWL-RTC code. Trying to pull this into LITMUS^RT staging (as of 9/20/2012) to get LITMUS^RT running on the PandaBoard. Conflicts: Makefile fs/exec.c include/linux/fs.h kernel/fork.c

| * OMAP2+: mailbox: fix lookups for multiple mailboxesSebastien Jan2012-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * OMAP: hwmod: fix the i2c-reset timeout during bootupAvinash.H.M2012-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sequence of _ocp_softreset doesn't work for i2c. The i2c module has a special sequence to reset the module. The sequence is - Disable the I2C. - Write to SOFTRESET bit. - Enable the I2C. - Poll on the RESETDONE bit. The sequence is implemented as a function and the i2c_class is updated with the correct 'reset' pointer. omap_hwmod_softreset function is implemented which triggers the softreset by writing into sysconfig register. On following this sequence, i2c module resets properly and timeouts are not seen.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since we cannot trust (or even reliably find) the OMAP I2C peripheral unit's own revision register, we must inform the OMAP i2c driver of which IP version it is running on.

| * I2C: OMAP2+: increase omap_i2c_dev_attr flags from u8 to u32Andy Green2012-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As part of removing cpu_...() from the OMAP I2C driver, we need to convert the CPU tests into functionality flags that are set by hwmod class in the same way the IP revision is. More flags are needed than will fit in the existing u8 flags member of omap_i2c_dev_attr. These flags can refer to options inside the IP block but they are most needed for information about cpu implementation specific options that are not part of the IP block itself. For example, how the CPU data bus is wired to the IP block databus differs between OMAP cpus and affects how you must shift the address in the IP block, but is not a feature of the IP block itself.

| * I2C: OMAP2+: Set hwmod flags to only allow 16-bit accesses to i2cAndy Green2012-08-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Peter Maydell noticed when running under QEMU he was getting errors reporting 32-bit access to I2C peripheral unit registers that are documented to be 8 or 16-bit only[1][2] The I2C driver is blameless as it wraps its accesses in a function using __raw_writew and __raw_readw, it turned out it is the hwmod stuff. However the hwmod code already has a flag to force a perhipheral unit to only be accessed using 16-bit operations. This patch applies the 16-bit only flag to the 2430, OMAP3xxx and OMAP44xx hwmod structs. 2420 was already correctly marked up as 16-bit. The 2430 change will need testing by TI as arranged in the comments to the previous patch version. When the 16-bit flag is or-ed with other flags, it is placed first as requested in comments.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Seperated the building of Scatter gather list to Map function. The list is created when the Map function is created and deleted when the unmap function is called. Previously this list was created during flush function and deleted during the invalidate function. The previous implementation would fail if the Users call the invalidate function directly without calling flush function, as it would require calling flush function prior to calling invalidate function. The previous implementation also includes the overhead in creating and deleting the SG list for every flush and invalidate calls. 3. Changed the logic to track mapping object based on MPU VA instead of page aligned MPU VA. This is because if there are 2 MPU buffers with virtual addresses within the Page boundary, then there would be 2 Mapping objects with same virtual address. 4. Delete the DMM pools only when all the handles to IODMM are closed. The ioctl DMM_IOCDELETEPOOL can be deprecated with this change. 5. Added the SYS ADMIN check for create dmm pools, and set tlb entry ioctls. This code is currently kept commented out. 6. DMA Flush APIs are still optionally selected using CONFIG_DMM_DMA_API option. This is not selected by default. Signed-off-by: Hari Kanigeri <h-kanigeri2@ti.com> omap:iodmm-send notification on close only when resources not free Instead of sending the notification on every IOMMU close, send it only when there are still mapped resources to avoid the remote processor accessing these resources. After compelting the notification, the iommu release function can safely remove the mapped entries.
