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.

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.

The secure sram context save uses dma channels 0 and 1. In order to avoid collision between kernel DMA transfers and ROM code dma transfers, we need to reserve DMA channels 0 1 on high security devices. A bug in ROM code leaves dma irq status bits uncleared. Hence those irq status bits need to be cleared when restoring DMA context after off mode. There was also a faulty parameter given to PPA in the secure ram context save assembly code, which caused interrupts to be enabled during secure ram context save. This caused the save to fail sometimes, which resulted the saved context to be corrupted, but also left DMA channels in secure mode. The secure mode DMA channels caused "DMA secure error with device 0" errors to be displayed.

The function omap3_save_secure_ram() is now called only once during the initialization of the device and consequent sleep cycles will re-use the same saved contents for secure RAM. Users who need secure services should do secure RAM saving before entering off-mode, if a secure service has been accessed after last save. There are both latency and reliability issues with saving secure RAM context in the idle path. The context save uses a hardware resource which takes an order of hundreds of milliseconds to initialize after a wake up from off-mode, and also there is no way of checking whether it is ready from kernel side or not. It just crashes if you use it too quickly Additional fix to ensure scratchpad save is done after secure RAM by Roger Quadros.

UART3 is in the PER powerdomain. If PER goes idle/inactive independently of CORE, for UART3 to wakeup it must have its wakeup enable bits setup in PM_WKEN_PER. This patch enables these bits. The reason it works when PER and CORE work together is because when CORE goes inactive/retention, the IOPAD wakeups are enabled and trigger UART3 wakeup. Without this patch, when the UART inactivity timer fires for UART3, its clocks are disabled and it's unable to wakeup so will be unusable until PER is awoken by another source. Another way of testing is by keeping CORE on during suspend but allowing PER to hit retention # echo 3 > /debug/pm_debug/core_pwrdm/suspend then enter suspend # echo mem > /sys/power/state Without this patch, UART3 will be unable to wakeup the system.
