commit: b1268d3737c6316016026245eef276eda6b0a621 From: Roland Stigge <[email protected]> Date: Thu, 20 Sep 2012 10:48:03 +0200 Subject: gpio-lpc32xx: Fix value handling of gpio_direction_output()
For GPIOs of gpio-lpc32xx, gpio_direction_output() ignores the value argument (initial value of output). This patch fixes this by setting the level accordingly.
