+[workaround for missing swakeup on am33xx]
+
+This SOC is missing the swakeup line, it will not detect SDIO irq
+while in suspend.

+
+In suspend the fclk is off and the module is disfunctional. Even
+register reads will fail. A small logic in the host will request
+fclk restore, when an external event is detected. Once the clock
+is restored, the host detects the event normally. Since am33xx
+doesn't have this line it never wakes from suspend.
+
+The workaround is to reconfigure the dat1 line as a GPIO upon
+suspend. To make this work, we need to set 1) the named pinctrl
+states "default", "active" and "idle", 2) the gpio detecting
+sdio irq in suspend and 3) compatibe section, see example below.
+The MMC driver will then toggle between active and idle during
+the runtime. If configuration is incomplete, a warning message is
+emitted "falling back to polling".  Mind not every application
+needs SDIO irq, e.g. MMC cards Affected chips are am335x,
+probably others
