+&i2c3 {

+       pinctrl-1 = <&tdm_c_din3_a_pins>;

Note: without setting this *pinctrl-1* configuration RTC wake up
feature works as expected.

As pointed out by Martin, the pinctrl-1 here makes no sense for RTC on
i2c. If the rtc is on an I2C of AO bank, the pinctrl-0 is likely to be
wrong as well.
