* OMAP3: PM: Program SDRC to send self refresh on timeout of AUTO_CNTRajendra Nayak2009-11-111-1/+15
| | | | | | | | | | | | | | | | | | | | Due to an OMAP3 errata (1.142), on HS/EMU devices SDRC should be programed to issue automatic self refresh on timeout of AUTO_CNT = 1 prior to any transition to OFF mode. This is needed only on sil rev's ES3.0 and above. This patch enables the above needed WA in the SDRC power register value stored in scratchpad, so that ROM code restores this value in SDRC POWER on the wakeup path. The original SDRC POWER register value is stored and restored back in omap_sram_idle() function. This fixes some random crashes observed while stressing suspend on HS/EMU devices.

* OMAP3: PM: Fix PLL_MOD CLKEN offset in scratchpadKalle Jokiniemi2009-11-111-1/+1
| | | | | | | | | | | | | | | | | | The CM_CLKEN_PLL register saved in scratchpad memory was wrongly using offset of 0x0004 instead of 0x0000. The effect of this was that boot ROM code would restore the wrong value when waking up from off mode. This wrong value, however, will be overwritten by prcm context restore. Still, a short period of wrong clock settings in CM_CLKEN_PLL remained between ROM code and prcm context restore. This is fixed by the patch.

* OMAP3 PM: off-mode support for HS/EMU devicesTero Kristo2009-11-111-1/+7
| | | | | | | | | 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: headers: Move remaining headers from include/mach to include/platTony Lindgren2009-10-201-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the remaining headers under plat-omap/include/mach to plat-omap/include/plat. Also search and replace the files using these headers to include using the right path. This was done with: #!/bin/bash mach_dir_old="arch/arm/plat-omap/include/mach" plat_dir_new="arch/arm/plat-omap/include/plat" headers=$(cd $mach_dir_old && ls *.h) omap_dirs="arch/arm/*omap*/ \ drivers/video/omap \ sound/soc/omap" other_files="drivers/leds/leds-ams-delta.c \ drivers/mfd/menelaus.c \ drivers/mfd/twl4030-core.c \ drivers/mtd/nand/ams-delta.c" for header in $headers; do old="#include <mach\/$header" new="#include <plat\/$header" for dir in $omap_dirs; do find $dir -type f -name \*.[chS] | \ xargs sed -i "s/$old/$new/" done find drivers/ -type f -name \*omap*.[chS] | \ xargs sed -i "s/$old/$new/" for file in $other_files; do sed -i "s/$old/$new/" $file done done for header in $(ls $mach_dir_old/*.h); do git mv $header $plat_dir_new/ done Signed-off-by: Tony Lindgren <tony@atomide.com>

| | | | | | | | | | | | New struct omap_globals contains the omap processor specific module bases. Use omap_globals to set the various base addresses to make detecting omap chip type simpler. Also introduce OMAP1_IO_ADDRESS and OMAP2_IO_ADDRESS for future multi-omap patches. Signed-off-by: Tony Lindgren <tony@atomide.com>
* ARM: OMAP2: Add common register access for 24xx and 34xxPaul Walmsley2008-04-141-0/+74
This patch adds common register access for 24xx and 34xx power and clock management in order to share code between 24xx and 34xx. Only change USB platform init code to use new register access, other access will be changed in later patches.
