From 832e61418eedfea172bd2fdfd0ea0d199cc70a9d Mon Sep 17 00:00:00 2001 From: Stefan Roese Date: Wed, 21 Jan 2009 17:12:10 +0100 Subject: USB: Add config option to call ehci_hcd_init() again after EHCI reset This patch adds the config option CONFIG_EHCI_HCD_INIT_AFTER_RESET to call ehci_hcd_init() again after ehci_reset() is executed. This is needed for the upcoming VCT EHCI support which needs to re-init the hcd part again after the EHCI CMD_RESET is executed.
