From mboxrd@z Thu Jan 1 00:00:00 1970 From: Sebastian Andrzej Siewior Subject: [PATCH 2/2] input: ti_am33x_tsc: make the documentation for the ti,wire-config parameter clear Date: Thu, 19 Dec 2013 17:25:51 +0100 Message-ID: <1387470351-4696-2-git-send-email-bigeasy@linutronix.de> References: <1387470351-4696-1-git-send-email-bigeasy@linutronix.de> Mime-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: QUOTED-PRINTABLE Return-path: In-Reply-To: <1387470351-4696-1-git-send-email-bigeasy@linutronix.de> Sender: linux-kernel-owner@vger.kernel.org To: linux-doc@vger.kernel.org, linux-kernel@vger.kernel.org Cc: Felipe Balbi , devicetree@vger.kernel.org, Rob Herring , Kumar Gala , Pawel Moll , Mark Rutland , Stephen Warren , Ian Campbell , Rob Landley , Sebastian Andrzej Siewior , Dmitry Torokhov List-Id: devicetree@vger.kernel.org The document says "first four bits" and means the upper nibble. Most people would probably agree that the first four bits are bits 0=E2=80=A6= 3 and that is the lower nibble. This patch updates the documentation so it is clear what is meant.
