| * OMAP3: PM: Program SDRC to send self refresh on timeout of AUTO_CNTRajendra Nayak2009-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 secure SRAM context save/restoreKalle Jokiniemi2009-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Looking closer at this I have found that it had been broken almost 2 years ago with commit 2418996e3b100114edb2ae110d5d4acb928909d2, PM fixes for OMAP1. The definite reason for broken omapfb/lcdc behavoiur in PM mode appeared to be ARM_IDLECT1:IDLIF_ARM (bit 6) put into idle regardless of LCD DMA possibly running. The bit were set based on return value of the omap_dma_running() function that did not check for dedicated LCD DMA channel status. The patch below fixes this. Note that the hardcoded register value will be fixed during the next merge cycle to use OMAP_LCDC_ defines. Currently the OMAP_LCDC_ defines are local to drivers/video/omap/lcdc.c, so let's not start moving those right now.
