Message-Id: <1283015148-10747-5-git-send-email-gbean@codeaurora.org>
Date: Sat, 28 Aug 2010 10:05:48 -0700
From: Gregory Bean <gbean@...eaurora.org>
To: dwalker@...eaurora.org
Cc: linux-arm-msm@...r.kernel.org,
linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org,
Gregory Bean <gbean@...eaurora.org>
Subject: [PATCH 5/5 v4] msm: gpio: Remove tlmm routines obsoleted by gpiomux.
Now that all supported gpio_tlmm_config-using boards
are using gpiomux, remove the deprecated code.
