* OMAP3 PM: off-mode support for HS/EMU devicesTero Kristo2009-11-11
| | | | | | | | | For HS/EMU devices, some additional resources need to be saved/restored for off-mode support. Namely, saving the secure RAM and a pointer to it in the scratchpad. Signed-off-by: Tero Kristo <tero.kristo@nokia.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
* OMAP: PM: DMA context save/restore for off-mode supportTero Kristo2009-11-11
| | | | | | | | | | For HS/EMU devices, these additional features are also used: - DMA interrupt disable routine added - Added DMA controller reset to DMA context restore Signed-off-by: Tero Kristo <tero.kristo@nokia.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>

* OMAP3: PM: MPU off-mode supportRajendra Nayak2009-11-11
| | | | | | | | Adds a 'save_state' option when calling into SRAM idle function and adds some minor cleanups of SRAM asm code. Signed-off-by: Rajendra Nayak <rnayak@ti.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
* OMAP3: PM: Restore MMU table entryRajendra Nayak2009-11-11
| | | | | | | | | | | | | During the MMU restoration on the restore path from MPU OFF, the page table entry for the page consisting of the code being executed is modified to make MMU return VA=PA. The MMU is then enabled and the original entry is being stored in scratchpad. This patch reads the original values stored in scratchpad, and restores them back.

* OMAP3: PM: handle PER/NEON/CORE in idleRajendra Nayak2009-11-11
| | | | | | | | | | | Expand the powerdomains handled in the idle path to include PER, NEON and CORE. This includes properly clearing the previous powerstates, linking NEON state to MPU state and calling the UART prepare functions for only the appropraite powerdomain transitions (CORE for UART1,2, PER for UART3.)

However, this change causes problems on mach-omap1: BUG: mapping for 0xe0000000 at 0xe0000000 overlaps vmalloc space BUG: mapping for 0xe1000000 at 0xe1000000 overlaps vmalloc space Fix this by creating separate vmalloc.h files for mach-omap1 and mach-omap2.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch remap L3 and L4 io space to get more kernel address space. With this patch, 512 MB of IO space is reclaimed. Some more combinations are possible but to make it uniform across OMAP24XX, OMAP34XX and OMAP4430, these io combinations are chosen Once this is reviewed and tested sufficiently, a documentation entry can be created to ease up reading and debugging.

| * omap: Split OMAP2_IO_ADDRESS to L3 and L4Santosh Shilimkar2009-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch splits OMAP2_IO_ADDRESS to OMAP2_L3_IO_ADDRESS and OMAP2_L4_IO_ADDRESS to reclaim more IO space. The omap_read*() and omap_write*() functions will work only over L4 address space. Current omap kernel stack uses these functions only to access registers over L4 io address space Note that these macros should only be used when ioremap does not work. Please use ioremap instead in all new code. Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
