* omap: 3630: disable TLL SAR on 3630 ES1Anand Gadiyar2010-08-041-2/+10
| | | | | | | | | | | | | | | USBTLL Save-and-Restore is broken in 3630 ES1.0. Having it enabled could result in incorrect register restores as the OMAP exits off-mode. This could potentially result in unexpected wakeup events. (Refer 3630 errata ID i579) This is fixed in ES1.1. So disable it for ES1.0s.

* OMAP3 PM: Defining .pwrsts_logic_ret field for core power domain structureThara Gopinath2010-02-241-0/+2
| | | | | | | | | This patch adds the flag .pwrsts_logic_ret info for the core power domain in the associated powerdomain structure. This flag specifies the states core domain logic can hit in event of the domain entering retention. Signed-off-by: Thara Gopinath <thara@ti.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>
* OMAP2+ powerdomains/clockdomains: prepare for multi-OMAP configsPaul Walmsley2010-01-291-7/+7
| | | | | | | | | | | | | | | | | | | | | | Convert CONFIG_ARCH_OMAP34XX to CONFIG_ARCH_OMAP3, and CONFIG_ARCH_OMAP24XX to CONFIG_ARCH_OMAP2, in preparation for Tony's multi-OMAP patches. While here, update some copyrights, convert instances of "34xx" to "3xxx" where applicable, and convert preprocessor directives of the form #if defined(CONFIG_ARCH_OMAP2) | defined(CONFIG_ARCH_OMAP3) to #if defined(CONFIG_ARCH_OMAP2) || defined(CONFIG_ARCH_OMAP3) for standardization.

* OMAP2/3 clkdm/pwrdm: move wkdep/sleepdep handling from pwrdm to clkdmPaul Walmsley2010-01-261-144/+1
| | | | | | | | | | | | | | | Move clockdomain wakeup dependency and sleep dependency data structures from the powerdomain layer to the clockdomain layer, where they belong. These dependencies were originally placed in the powerdomain layer due to unclear documentation; however, it is clear now that these dependencies are between clockdomains. For OMAP2/3, this is not such a big problem, but for OMAP4 this needs to be fixed. Thanks to Benoît Cousson <b-cousson@ti.com> for his advice on this patch.

* PM: Disable usb host HW save and restoreKalle Jokiniemi2009-11-111-1/+7
| | | | | | | | | | The hardware SAVEANDRESTORE mechanism seems to leave USB HOST power domain permanently into active state after one transition from off to active state. Disabling for now.

* omap: headers: Move remaining headers from include/mach to include/platTony Lindgren2009-10-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* [ARM] OMAP3 powerdomains: make USBTLL SAR only available on ES3.1 and beyondPaul Walmsley2009-02-231-2/+23
| | | | | | | | | | | | | Richard Woodruff writes that chip errata prevent USBTLL SAR from working on OMAP3 ES levels before ES3.1: http://marc.info/?l=linux-arm-kernel&m=123319614808833&w=2 Update the OMAP3 powerdomain structures appropriately.

* [ARM] OMAP3: update ES level flags to discriminate between post-ES2 revisionsPaul Walmsley2009-02-231-3/+3
| | | | | | | | | | | | | | | Some OMAP3 chip behaviors change in ES levels after ES2. Modify the existing omap_chip flags to add options for ES3.0 and ES3.1. Add a new macro, CHIP_GE_OMAP3430ES2, to cover ES levels from ES2 onwards - a common pattern for OMAP3 features. Update all current users of the omap_chip macros to use this new macro. Also add CHIP_GE_OMAP3430ES3_1 to cover the USBTLL SAR errata case (described and fixed in the following patch) Signed-off-by: Paul Walmsley <paul@pwsan.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [ARM] OMAP3 PRCM: add DPLL1-5 powerdomains, clockdomains; mark clocksPaul Walmsley2009-02-081-0/+31
| | | | | | | | | | | | | | Each DPLL exists in its own powerdomain (cf 34xx TRM figure 4-18) and clockdomain; so, create powerdomain and clockdomain structures for them. Mark each DPLL clock as belonging to their respective DPLL clockdomain. cf. 34xx TRM Table 4-27 (among other references). linux-omap source commits are acdb615850b9b4f7d1ab68133a16be8c8c0e7419 and a8798a48f33e9268dcc7f30a4b4a3ce4220fe0c9.

* [ARM] OMAP3: move USBHOST SAR handling from clock framework to powerdomain layerPaul Walmsley2009-02-081-0/+1
| | | | | | | | | | | | | | | | | | Remove usbhost_sar_fclk from the OMAP3 clock framework. The bit that the clock was tweaking doesn't actually enable or disable a clock; it controls whether the hardware will save and restore USBHOST state when the powerdomain changes state. (That happens to coincidentally enable a clock for the duration of the operation, hence the earlier confusion.) In place of the clock, mark the USBHOST powerdomain as supporting hardware save-and-restore functionality. linux-omap source commit is f3ceac86a9d425d101d606d87a5af44afef27179.
