[linux-yocto] [PATCH 0/6] [linux-yocto-3.19] standard/base: Backport Braswell intel_idle driver patches from upstream kernel into Yocto Project linux kernel v3.19.

[wei.tee.ng at intel.com]

From: Ng Wei Tee <wei.tee.ng at intel.com>

Hi all,

This patch is to backport Braswell intel_idle driver patches that are
available in the upstream kernel into Yocto Project linux kernel v3.19.
These patches are to enable intel_idle driver to support C-states for
the Airmont core in the Cherrytrail and Braswell SOCs. The states are
similar to those of Silvermont in Baytrail, except both flavors of C6
states are faster.

This configuration was built and tested working on CherryHill platform.
Please review and provide feedback if any.

This patch is target for linux-yocto-3.19 on standard/base branch.

Thanks.

Regards,
Wei Tee
