Subject: [PATCH/Master] ARM/MXS: the GPIO bitkeeper enable logic is inverse to the pullup enable logic
Date: Wed, 11 Jul 2012 11:15:58 +0200	[thread overview]
Message-ID: <201207111115.58627.jbe@pengutronix.de> (raw)

While a set bit enables the pullup (if exists) it disables the bitkeeper (if
exists). Both features are using the same register bit and only one of this
feature is present on a per pin base.
