Re: [PATCH 1/2] msm: Add gpio support for 8960

From: Rohit Vaswani
Date: Thu Mar 17 2011 - 18:54:59 EST


Please disregard (1/2) - no second patch
Will re-send with appropriate subject

This patch adds GPIO support for 8960. The board file includes the
gpiomux configs and we now use gpio-v2 for 8960.
