-Subject: pinctrl: qcom: use scm_call to route GPIO irq to Apps
-
-For IPQ806x targets, TZ protects the registers that are used to
-configure the routing of interrupts to a target processor.
-To resolve this, this patch uses scm call to route GPIO interrupts
-to application processor. Also the scm call interface is changed.
