The reset on apq8064 is provided on gpio78 function1. We need to configure gpio78 to function as ps_hold and write to base of the register to get the device rebooted.
First two patches in this patchset adds necessary DT support for apq8064-pinctrl and DT support to mux gpio_78 as ps_hold function.
Third patch documents the ps_hold function in apq8064-pinctrl DT binding
Fourth implements the actual reset by initialising arm_pm_restart to a reset function if ps_hold function is programmed in the pinctrl driver.
This is v2 with below changes since v1: 1. Added #error log as suggested by Kumar Gala 2. Correct interrupts in DT from 32 to 16 based on Bjorn's new patch in bindings 3. Replaced hardcoding in DT with IRQ_TYPE_LEVEL_HIGH for interrupt level type
