2010-12-21OMAP3630: PM: Erratum i583: disable coreoff if < ES1.2Eduardo Valentin
Limitation i583: Self_Refresh Exit issue after OFF mode Issue: When device is waking up from OFF mode, then SDRC state machine sends inappropriate sequence violating JEDEC standards. Impact: OMAP3630 < ES1.2 is impacted as follows depending on the platform: CS0: for 38.4MHz as internal sysclk, DDR content seen to be stable, while for all other sysclk frequencies, varied levels of instability seen based on varied parameters. CS1: impacted This patch takes option #3 as recommended by the Silicon erratum: Avoid core power domain transitioning to OFF mode. Power consumption impact is expected in this case. To do this, we route core OFF requests to RET request on the impacted revisions of silicon.

2010-12-21OMAP3630: PM: Disable L2 cache while invalidating L2 cachePeter 'p2' De Schrijver
While coming out of MPU OSWR/OFF states, L2 controller is reseted. The reset behavior is implementation specific as per ARMv7 TRM and hence $L2 needs to be invalidated before it's use. Since the AUXCTRL register is also reconfigured, disable L2 cache before invalidating it and re-enables it afterwards. This is as per Cortex-A8 ARM documentation. Currently this is identified as being needed on OMAP3630 as the disable/enable is done from "public side" while, on OMAP3430, this is done in the "secure side".

2010-12-21OMAP3630: PM: Erratum i608: disable RTANishanth Menon
Erratum id: i608 RTA (Retention Till Access) feature is not supported and leads to device stability issues when enabled. This impacts modules with embedded memories on OMAP3630 Workaround is to disable RTA on boot and coming out of core off. For disabling RTA coming out of off mode, we do this by overriding the restore pointer for 3630 as the first point of entry before caches are touched and is common for GP and HS devices. To disable earlier than this could be possible by modifying the PPA for HS devices, but not for GP devices.

2010-12-21OMAP3: PM: Erratum i581 support: dll kick strategyPeter 'p2' De Schrijver
Erratum i581 impacts OMAP3 platforms. PRCM DPLL control FSM removes SDRC_IDLEREQ before DPLL3 locks causing the DPLL not to be locked at times. IMPORTANT: *) This is not a complete workaround implementation as recommended by the silicon erratum. This is a support logic for detecting lockups and attempting to recover where possible and is known to provide stability in multiple platforms. *) This code is mostly important for inactive and retention. The ROM code waits for the maximum DLL lock time when resuming from off mode. So for off mode this code isn't really needed. *) counters are introduced here for eventual export to userspace once the cleanups are completed. This should eventually get refactored as part of cleanups to sleep34xx.S Cc: Kevin Hilman <khilman@deeprootsystems.com> Cc: Tony Lindgren <tony@atomide.com> Signed-off-by: Peter 'p2' De Schrijver <peter.de-schrijver@nokia.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
2010-12-21OMAP3: PM: Update clean_l2 to use v7_flush_dcache_allRichard Woodruff
Analysis in TI kernel with ETM showed that using cache mapped flush in kernel instead of SO mapped flush cost drops by 65% (3.39mS down to 1.17mS) for clean_l2 which is used during sleep sequences. Overall: - speed up - unfortunately there isn't a good alternative flush method today - code reduction and less maintenance and potential bug in unmaintained code This also fixes the bug with the clean_l2 function usage.

2010-12-21OMAP: pm.c correct the initcall for an early init.Thara Gopinath
omap2_common_pm_init is the API where generic system devices like mpu, l3 etc get initialized. This has to happen really early on during the boot and not at a later time. This is especially important with the new opp changes as these devices need to be built before the opp tables init happen. Today both are device initcalls and it works just because of the order of compilation. Making this postcore_initcall is ideal because the omap device layer init happens as a core_initcall and typically rest of the driver/device inits are arch_initcall or something lower.

2010-12-21OMAP2+: disable idle early in the suspend sequenceJean Pihet
Some bad interaction between the idle and the suspend paths has been identified: the idle code is called during the suspend enter and exit sequences. This could cause corruption or lock-up of resources. The solution is to move the calls to disable_hlt at the very beginning of the suspend sequence (ex. in omap3_pm_begin instead of omap3_pm_prepare), and the call to enable_hlt at the very end of the suspend sequence (ex. in omap3_pm_end instead of omap3_pm_finish).

2010-12-21Fix IGEPv2 second MMC channel power supplyMarc Zyngier
Commit 72f381ba056 (omap3: Remove VMMC2 regulator on IGEP v2) removed an unused regulator entry, but left the second MMC channel (used by the Libertas WLAN module) without link to power regulator. This causes the SDIO module to fail being detected. This patch adds the two regulators that actually feed the WLAN module (1v8 from the TWL4030 VIO LDO, and a fixed 3v3). With that patch, the second channel is properly detected. Details of the power supply implementation were kindly provided by Enric Balletbo i Serra.
