2012-06-27arm: tegra: baseband: add sysfs file for modem boot, etc.Steve Lin
1. Add sysfs file so the fild can load/unload host controller before modem power cycle. 2. Move modem boot irq to modem PM driver. 3. Add short autosuspend to optimize power consumption if the wake source of system resume is not modem. 4. Avoid LP0 abort if remote wakeup happens during L0/L2 -> L3 transition. 5. Fix deadlock in pm_notifier function.
