* [PATCH 2/3] Convert PowerPC MPC i2c to of_platform_driver from platform_driver

2 siblings, 1 reply; 6+ messages in thread
From: Jon Smirl @ 2008-01-28 14:42 UTC (permalink / raw)
To: i2c, linuxppc-dev
Convert MPC i2c driver from a platform_driver to a of_platform_driver. Add the ability to dynamically load i2c drivers based on device tree names. Routine names were changed from fsl_ to mpc_ to make them match the file name. Common code moved to powerpc-common.* Orginal ppc driver left intact for deletion when ppc arch is removed.

From: Jon Smirl @ 2008-01-28 14:42 UTC (permalink / raw)
To: i2c, linuxppc-dev
PowerPC device trees use a different naming convention than the Linux kernel. Provide alias names for i2c drivers in order to allow them to be loaded by device tree name. The OF_ID macro ensures that the aliases are only present in powerpc builds and separated into their own namespace.
