Subject: [PATCH] ulpi: add i.MX25 & 35 internal PHY ID
Date: Mon, 4 Oct 2010 14:23:32 +0200 [thread overview]
Message-ID: <1286195012-18999-1-git-send-email-eric@eukrea.com> (raw)
without this patch, the initialization of the OTG port in host mode
fails with :
ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver
mxc-ehci mxc-ehci.0: initializing i.MX USB Controller
ULPI transceiver vendor/product ID 0x0000/0x0000
ULPI ID does not match any known transceiver.
mxc-ehci mxc-ehci.0: unable to init transceiver, probably missing
