From c7f409e39e65cb007304da718b0a7b25a0144a0a Mon Sep 17 00:00:00 2001 From: Venkat Rao Date: Fri, 25 Mar 2011 20:37:47 -0400 Subject: [PATCH] mmc: tegra: add pm_flags Enable fast bcm4329 WIFI suspend/resume on Tegra2 board. This patch allows the mach-tegra support to tell the tegra MMC host controller to NOT turn off power for the MMC controller the WIFI part lives behind. Thus bcm4329 firmware doesn't need to be reloaded.
