From 097b53348f34a461d2b07081eae12d823cf3d729 Mon Sep 17 00:00:00 2001 From: Eric Miao Date: Sat, 27 Sep 2008 15:49:57 +0800 Subject: [ARM] ohci-pxa27x: introduce flags to avoid direct access to OHCI registers Direct access to USB host controller registers is considered to be not portable, and is usually a bad sign for poorly abstracted interface. Introduce .flags and .power_on_delay to "struct pxaohci_platform_data" so that most platforms don't bother to write their own .init/.exit() sequences.
