This also includes some of the code from core/tiomap3430_pwr.c, such as handle_hibernation_from_dsp() and dsp_clk_wakeup_event_ctrl(). Basically, all of the other code that directly reads or writes registers outside the IVA2 directly needs to be moved into arch/arm/mach-omap2. > 2.

If the DSP uses a peripheral, such as a GPTIMER or a McBSP, DSPBridge needs to reserve that device with the rest of Linux so some other Linux code isn't using it or doesn't try to use it, causing conflicts with DSPBridge. I guess the list that we need to worry about is in _tiomap.h as l4_peripheral_table[]. - Paul -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
