From ccac71a7f063ad31eb99fac37e95b70ff57f1354 Mon Sep 17 00:00:00 2001 From: Roger Quadros Date: Thu, 8 Nov 2012 19:18:08 +0200 Subject: mfd: omap-usb-host: override number of ports from platform data Both OMAP4 and 5 exhibit the same revision ID in the REVISION register but they have different number of ports i.e. 2 and 3 respectively. So we can't rely on REVISION register for number of ports on OMAP5 and depend on platform data (or device tree) instead.
