From 2971944582ff43b7dedbb460777052243ac9915a Mon Sep 17 00:00:00 2001 From: Rabin Vincent Date: Mon, 9 Aug 2010 12:54:43 +0100 Subject: ARM: 6307/1: mmci: allow the card detect GPIO value not to be inverted On some platforms, the GPIO value from the gpio_cd pin doesn't need to be inverted to get it active high. Add a cd_invert platform data parameter and change existing platforms using GPIO for CD (only Realview) to enable it.
