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. Signed-off-by: Vignesh R <vigneshr@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
