Subject: [PATCHv5 02/15] Documentation: dt: add the omap hwspinlock bindings document
Date: Wed, 30 Apr 2014 19:34:23 -0500 [thread overview]
Message-ID: <1398904476-26200-3-git-send-email-s-anna@ti.com> (raw)
In-Reply-To: <1398904476-26200-1-git-send-email-s-anna@ti.com>
HwSpinlock IP is present only on OMAP4 and other newer SoCs,
which are all device-tree boot only. This patch adds the
DT bindings information for OMAP hwspinlock module.

+OMAP4+ HwSpinlock Driver
+========================
+
+Required properties:
+- compatible: Should be "ti,omap4-hwspinlock" for
+ OMAP44xx, OMAP54xx, AM33xx, AM43xx, DRA7xx SoCs
+- reg: Contains the hwspinlock module register address space
+ (base address and length)
+- ti,hwmods: Name of the hwmod associated with the hwspinlock device
+- #hwlock-cells: Should be 1. The OMAP hwspinlock users will use a
+ 0-indexed relative hwlock number as the argument
+ specifier value for requesting a specific hwspinlock
+ within a hwspinlock bank.
+
+
+Example:
+
+/* OMAP4 */
+hwspinlock: spinlock@4a0f6000 {
+ compatible = "ti,omap4-hwspinlock";
+ reg = <0x4a0f6000 0x1000>;
+ ti,hwmods = "spinlock";
+ #hwlock-cells = <1>;
+};
