4.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Keerthy <j-keer...@ti.com> commit 0ea66f76ba17a4b229caaadd77de694111b21769 upstream. GPIO7 is configured in POWERHOLD mode which has higher priority over DEV_ON bit and keeps the PMIC supplies on even after the DEV_ON bit is turned off. This property enables driver to over ride the POWERHOLD value to GPIO7 so as to turn off the PMIC in power off scenarios.
