Subject: [PATCH 2/2] Documentation: Describe Device Tree bindings for GPIO Regulator driver
Date: Mon, 15 Oct 2012 14:17:00 +0100 [thread overview]
Message-ID: <1350307020-5910-2-git-send-email-lee.jones@linaro.org> (raw)
In-Reply-To: <1350307020-5910-1-git-send-email-lee.jones@linaro.org>
Here we specify all non-standard bindings which can be used when
requesting the use of an GPIO controlled regulator from Device Tree.

+GPIO controlled regulators
+
+Required properties:
+- compatible : Must be "regulator-gpio".
+
+Optional properties:
+- gpio-enable : GPIO to use to enable/disable the regulator.
+- startup-delay-us : Startup time in microseconds.
+- enable-active-high : Polarity of GPIO is active high (default is low).
+
+Any property defined as part of the core regulator binding defined in
+regulator.txt can also be used.
+
+Example:
+
+ mmciv: gpio-regulator {
+ compatible = "regulator-gpio";
+ regulator-name = "mmci-gpio-supply";
+ regulator-min-microvolt = <1800000>;
+ regulator-max-microvolt = <2600000>;
+ gpio = <&gpio0 24 0x4>;
+ startup-delay-us = <100000>;
+ enable-active-high;
+ regulator-boot-on;
+ };
