From 6e711c6a97a9d4122615018121d0d2a37b642ed1 Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Mon, 12 Nov 2012 16:20:32 +0100 Subject: libpayload: Add init() function to hci_t and rework uhci_reset() uhci_reset() differs in semantics compared to the other HCI's reset() implementations. uhci_reset() does some initialization work after a controller reset. So move the initialization part to a new function, uhci_reinit(), which get's exported through a new entry in hci_t: hci_t.init(). Warning: This breaks code that relies on the current, special, counterintuitive behaviour of uhci_reset(). If one wants a working host controller after calling hci_t.reset(), he should call hci_t.init() afterwards.
