+BCM7216 RESCAL reset controller
+===============================
+
+This document describes the BCM7216 RESCAL reset controller which is
+responsible for controlling the reset of the SATA and PCIe0/1 instances on
+BCM7216.
+
+Please also refer to reset.txt in this directory for common reset controller
+binding usage.
+
+Required properties:
+- compatible: should be brcm,bcm7216-pcie-sata-rescal
+- reg: register base and length
+- #reset-cells: must be set to 0
+
+Example:
+
+rescal: reset {
+ compatible = "brcm,bcm7216-pcie-sata-rescal";
+ reg = <0x8b2c800>;
+ #reset-cells = <0>;
+};
+
+&pcie0 {
+ resets = <&rescal>;
+};
