The boards saves 12mA with these states. It is based on the latest cpuidle consolidation from Robert Lee. The cpu can go to retention only if the other core is in WFI. If the other cpu is in WFI and we decoupled the gic from the cores, then we have the guarantee, it won't be wake up. It is up to the prcmu firmware to recouple the gic automatically after the power state mode is selected.

Remove the 3505-specific checking since CK_3505 flag is not used, and treat all AM35x clocks the same. This means that the SGX clock (the only AM35x clkdev not currently flagged for 3505) will now be registered on 3505, but that is harmless. That can be cleaned up when the clkdev nodes are removed in favor of them being registered by hwmod.

-- cgit From 414e41286e3aeb87de140ef4c75100f9344c32b2 Mon Sep 17 00:00:00 2001 From: Kevin Hilman Date: Tue, 8 May 2012 11:34:30 -0600 Subject: ARM: OMAP2+: WDTIMER integration: fix !PM boot crash, disarm timer after hwmod reset Without runtime PM enabled, hwmod needs to leave all IP blocks in an enabled state by default so any driver access to the HW will succeed. This is accomplished by seting the postsetup_state to enabled for all hwmods during init when runtime PM is disabled. Currently, we have a special case for WDT in that its postsetup_state is always set to disabled. This is done so that the WDT is disabled and the timer is disarmed at boot in case there is no WDT driver. This also means that when runtime PM is disabled, if a WDT driver *is* built in the kernel, the kernel will crash on the first access to the WDT hardware. We can't simply leave the WDT module enabled, because the timer is armed by default after reset. That means that if there is no WDT driver initialzed or loaded before the timer expires, the kernel will reboot. To fix this, a custom reset method is added to the watchdog class of omap_hwmod. This method will *always* disarm the timer after hwmod reset. The WDT timer then will only be rearmed when/if the driver is loaded for the WDT. With the timer disarmed by default, we no longer need a special-case for the postsetup_state of WDT during init, so it is removed. Any platforms wishing to ensure the watchdog remains armed across the entire boot boot can simply disable the reset-on-init feature of the watchdog hwmod using omap_hwmod_no_setup_reset(). Tested on 3530/Overo, 4430/Panda. NOTE: on 4430, the hwmod OCP reset does not seem to rearm the timer as documented in the TRM (and what happens on OMAP3.) I noticed this because testing the HWMOD_INIT_NO_RESET feature with no driver loaded, I expected a reboot part way through the boot, but did not see a reboot. Adding some debug to read the counter, I verified that right after OCP softreset, the counter is not firing. After writing the magic start sequence, the timer starts counting. This means that the timer disarm sequence added here does not seem to be needed for 4430, but is technically the correct way to ensure the timer is disarmed, so it is left in for OMAP4. Special thanks to Paul Walmsley for helping brainstorm ideas to fix this problem.
