From 72053353583230952c4b187e110e9da00dfc3afb Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Wed, 8 Feb 2012 15:52:47 +0100 Subject: ARM: orion: Fix USB phy for orion5x. The patch "ARM: orion: Consolidate USB platform setup code.", commit 4fcd3f374a928081d391cd9a570afe3b2c692fdc broke USB on TS-7800 and other orion5x boards, because the wrong type of PHY was being passed to the EHCI driver in the platform data. Orion5x needs EHCI_PHY_ORION and all the others want EHCI_PHY_NA. Allow the mach- code to tell the generic plat-orion code which USB PHY enum to place into the platform data. Version 2: Rebase to v3.3-rc2.
