From f513d22c9cb09ff95a0c2d26e18940fbda50d6db Mon Sep 17 00:00:00 2001 From: Vignesh R Date: Wed, 14 Oct 2015 19:24:25 +0530 Subject: [PATCH] ARM: dts: am437x-gp-evm: Add wakeup interrupt source for pixcir_i2c_ts On am437x-gp-evm, pixcir_i2c_ts can wakeup the system from low power state via pinctrl and IO daisy chain using generic wakeirq framework. With commit 3fffd1283927 ("i2c: allow specifying separate wakeup interrupt in device tree") i2c core allows optional wakeirq to be specified via device tree. Add wakeup irq entry to enable pixcir_i2c_ts to wake the system from low power state.
