From d8f64797c5ff3351a54830bba2cbc7e0b00e4613 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Wed, 6 Nov 2013 14:00:25 -0700 Subject: [PATCH] ARM: tegra: add missing clock documentation to DT bindings Many of the Tegra DT binding documents say nothing about the clocks or clock-names properties, yet those are present and required in DT files. This patch simply updates the documentation file to match the implicit definition of the binding, based on real-world DT content. All Tegra bindings that mention clocks are updated to have consistent wording and formatting of the clock-related properties.
