From 970f4be85ae6ecf97b711a3a2a1d5cecd3ea0534 Mon Sep 17 00:00:00 2001 From: Heikki Lindholm Date: Mon, 6 Sep 2010 22:30:45 +0300 Subject: firewire: ohci: activate cycle timer register quirk on Ricoh chips The Ricoh FireWire controllers appear to have the non-atomic cycle timer register access bug, so, activate the driver workaround by default. The behaviour was observed on: Ricoh Co Ltd R5C552 IEEE 1394 Controller [1180:0552] and Ricoh Co Ltd R5C832 IEEE 1394 Controller [1180:0832] (rev 04).

Hence let make descend into drivers/firewire/ also if that option is off. The stand-alone driver drivers/ieee1394/init_ohci1394_dma* will soon be moved into drivers/firewire/ too and will require the same makefile fix. Side effect: As mentioned in https://bugzilla.novell.com/show_bug.cgi?id=586172#c24 this influences the order in which either firewire-ohci or ohci1394 is going to be bound to an OHCI-1394 controller in case of a modular build of both drivers if no modprobe blacklist entries are configured. However, a user of such a setup cannot expect deterministic behavior anyway. The Kconfig help and the migration guide at ieee1394.wiki.kernel.org recommend blacklist entries when a dual IEEE 1394 stack build is being used. (The coexistence period of the two stacks is planned to end soon.)
