Subject: [PATCH] x86/platform/intel/iosf: Add better description of IOSF
 driver in config

From: "David E. Box" <david.e.box@...ux.intel.com>

commit ced3ce760b8df08e8bafba44f6b40407df2d0402 upstream.

Adds better description of IOSF driver to determine when it
should be enabled. Also moves the Kconfig option to "Processor
type and features" menu from main configuration menu.
