From 7061dec40c07265f819ae0a6842846f74f889aa9 Mon Sep 17 00:00:00 2001 From: Ondrej Zary Date: Fri, 6 Feb 2015 23:11:56 +0100 Subject: [PATCH] aha1542: Fix bus reset Bus reset always fails because aha1542_reset waits for the controller to assert the INIT bit (Mailbox Initialization Required) which it never does. This bit is asserted only after host reset. Remove the requirement for INIT bit (we really need only the IDLE bit).
