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> --- Since v1: - correct interrupt flag. - add comment wrt wakeup interrupt. arch/arm/boot/dts/am437x-gp-evm.dts | 9 +++++++++ 1 file changed, 9 insertions(+)
