From 09173b589d547c002b6a2b560e150c4d7bb56c99 Mon Sep 17 00:00:00 2001 From: Anand Gadiyar Date: Wed, 16 Feb 2011 16:47:19 +0530 Subject: [PATCH] arm: omap4: 4430sdp: drop ehci support Most revisions of the OMAP4 Blaze/SDP platform do not have the EHCI signals routed by default. The pads are routed for the alternate HSI functionality instead, and explicit board modifications are needed to route the signals to the USB PHY on the board. Also, turning on the PHY connected to the EHCI port causes a board reboot during bootup due to an unintended short on the rails - this affects many initial revisions of the board, and needs a minor board mod to fix (or as a workaround, one should not attempt to power on the USB PHY). Given that these boards need explicit board mods to even get EHCI working (separate from the accidental short above), we should not attempt to enable EHCI by default. So drop the EHCI support from the board files for the Blaze/SDP platforms.
