Subject: [PATCH V7 5/7] POWER/cpuidle: Generic POWER CPUIDLE driver supporting PSERIES.
Date: Tue, 29 Oct 2013 16:31:49 +0530 [thread overview]
Message-ID: <20131029110148.31547.8944.stgit@deepthi.in.ibm.com> (raw)
In-Reply-To: <20131029110052.31547.82682.stgit@deepthi.in.ibm.com>
This patch includes cleanup and refactoring of the
existing code to make the driver POWER generic.
* Re-naming the functions from pseries to generic power.
* Re-naming the backend driver from pseries_idle to
ibm-power-idle.
