From 192a1acfbd600fea8a596b7d92572b70131b7738 Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Thu, 17 Nov 2011 14:11:58 +0100 Subject: HID: wiimote: Rename driver to allow multiple source files Extension and sound support for the wiimote are quite complex and will be implemented in separate source files. Hence rename the current driver to "-core" suffix so multiple files can be linked into this module.

This adds a separate source file which handles all extensions and can be disabled at compile-time. The driver reacts on "plug"-events on the extension port and starts a worker which initializes or deinitializes the extensions. Currently, the initialization logic is not fully understood and we can only detect and enable all extensions when all extensions are deactivated. Therefore, we need to disable all extensions, then detect and activate them again to react on "plug"-events. However, deactivating extensions will generate a new "plug"-event and we will never leave that loop. Hence, we only support extensions if they are plugged before the wiimote is connected (or before the ext-input device is opened). In the future we may support full extension hotplug support, but reverse-engineering this may take a while.
