[PATCH 2/3] ARM: dts: imx25: don't configure reserved pad settings

Uwe Kleine-König u.kleine-koenig at pengutronix.de
Tue Jul 5 13:19:52 PDT 2016


Two dts files specified reserved bits in their pad setting value for
some pins. This commit just unsets the reserved bits, which matches the
hardware behaviour when writing a 1 to a reserved bit.
