+GPIO reset controller
+=====================
+
+A GPIO reset controller controls a single GPIO that is connected to the reset
+pin of a peripheral IC. Please also refer to reset.txt in this directory for
+common reset controller binding usage.
+
+Required properties:
+- compatible: Should be "gpio-reset"
+- reset-gpios: A gpio used as reset line. The gpio specifier for this property
+ depends on the gpio controller that provides the gpio.
+- #reset-cells: 0, see below
+
+Optional properties:
+- reset-delay-us: delay in microseconds. The gpio reset line will be asserted for
+ this duration to reset.
+- initially-in-reset: boolean. If not set, the initial state should be a
+ deasserted reset line. If this property exists, the
+ reset line should be kept in reset.
+
+example:
+
+sii902x_reset: gpio-reset {
+ compatible = "gpio-reset";
+ reset-gpios = <&gpio5 0 GPIO_ACTIVE_LOW>;
+ reset-delay-us = <10000>;
+ initially-in-reset;
+ #reset-cells = <0>;
+};
+
+/* Device with nRESET pin connected to GPIO5_0 */
+sii902x@39 {
+ /* ... */
+ resets = <&sii902x_reset>; /* active-low GPIO5_0, 10 ms delay */
+};

- help
- Most USB controllers have the physical layer signalling part
- (commonly called a PHY) built in. However, dual-role devices
- (a.k.a. USB on-the-go) which support being USB master or slave
- with the same connector often use an external PHY.
-
- The drivers in this submenu add support for such PHY devices.
- They are not needed for standard master-only (or the vast
- majority of slave-only) USB interfaces.
