From bbbc1ae9219ae8c8098c0af14060da5cb0d37e53 Mon Sep 17 00:00:00 2001 From: Jonathan Solnit Date: Fri, 24 Feb 2012 11:30:18 +0000 Subject: ARM:OMAP+:MMC: Add parameters to MMC init Add parameters to the OMAP MMC initialization function so the board can mask host capabilities and set the maximum clock frequency. While the OMAP supports a certain set of MMC host capabilities, individual boards may be more restricted and the OMAP may need to be configured to match the board. The PRG_SDMMC1_SPEEDCTRL bit in the OMAP3 is an example.
