From a781c97aaa1712449968d41ae30dc673877058ab Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Mon, 27 Apr 2015 14:36:23 +0200 Subject: [PATCH] sunxi: usb: Remove sunxi_usbc_get_io_base function This is the only function left in sunxi/usbc.c which is not phy related, so remove it. This is a preparation patch for turning the usbc.c code into a proper usb phy driver.
