From e446630c960946b5c1762e4eadb618becef599e7 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Mon, 29 Mar 2010 08:57:56 +0000 Subject: Add hotplug support to mcp251x driver Chip model can now be selected directly by matching the modalias name (instead of filling the .model field in platform_data), and allows the module to be auto-loaded. Previous behaviour is of course still supported. Convert the two in-tree users to this feature (icontrol & zeus). Tested on an Zeus platform (mcp2515).

To avoid further confusion, this patch fixes it by renaming the member to "osc_freq". That way, also non mainline users will notice the change. The platform code for the relevant boards is updated accordingly. Furthermore, pre-defined values are now used for the members "ocr" and "cdr".
