 Required properties:
 - compatible: "brcm,bcm2835-gpio"
+- compatible: should be one of:
+  "brcm,bcm2835-gpio" - BCM2835 compatible pinctrl
+  "brcm,bcm7211-gpio" - BCM7211 compatible pinctrl
+  "brcm,bcm2711-gpio" - BCM2711 compatible pinctrl
+  "brcm,bcm7211-gpio" - BCM7211 compatible pinctrl
 - reg: Should contain the physical address of the GPIO module's registers.
 - gpio-controller: Marks the device node as a GPIO controller.
 - #gpio-cells : Should be two. The first cell is the pin number and the
   second cell is used to specify optional parameters:
   - bit 0 specifies polarity (0 for normal, 1 for inverted)
 - interrupts : The interrupt outputs from the controller. One interrupt per
-  individual bank followed by the "all banks" interrupt.
+  individual bank followed by the "all banks" interrupt. For BCM7211, an
+  additional set of per-bank interrupt line and an "all banks" wake-up
+  interrupt may be specified.
 - interrupt-controller: Marks the device node as an interrupt controller.
 - #interrupt-cells : Should be 2.
   The first cell is the GPIO number.
