msm_otg: hack to allow automatic usb host mode (externally powered) Force ID_A (host mode + charging) on detection of proprietary charger (Apple-compatible charger with voltage on D+/D-). Unforce ID_A on PMIC: BSV clear (detection of loss of charger). Use charger type ACA_DOCK and allow up to 1.5A charge rate in host mode.

msm_otg: hack to allow manual usb host mode (externally powered) Enable debugfs /sys/kernel/debug/msm_otg/mode for manual otg mode manipulation. Always force requested mode (none, peripheral, host). Use ID_A bit instead of ID for host mode.

Note: There are no provisions for charger detection when setting host mode manually.
