From e8e51d29205b3c507a2e6126e18f76f42b49f5ca Mon Sep 17 00:00:00 2001 From: Ajay Kumar Gupta Date: Sun, 22 Nov 2009 10:11:28 -0800 Subject: omap3evm: ehci: Update EHCI support on OMAP3EVM (Rev >= E) Added runtime programming for the differences in EHCI interface between OMAP3EVM revisions (Rev >= E) and (Rev < E). Changes: - EHCI PHY reset GPIO pin is 21 on Rev >= E while Rev < E uses GPIO pin 135. - Rev >= E uses EHCI Vbus enable GPIO22 line. - Rev >= E uses GPIO61 to select EHCI port either on main board or on Mistral Daughter Card (MDC). OMAP3EVM Rev < E doesn't have EHCI port on main board. - Currently GPIO61 it programmed to enable EHCI port on main board only.
