Subject: [PATCH v4 07/10] powerpc/powernv: set power_save func after the idle states are initialized
Date: Tue, 24 May 2016 18:45:11 +0530 [thread overview]
Message-ID: <1464095714-48772-8-git-send-email-shreyas@linux.vnet.ibm.com> (raw)
In-Reply-To: <1464095714-48772-1-git-send-email-shreyas@linux.vnet.ibm.com>
pnv_init_idle_states discovers supported idle states from the
device tree and does the required initialization. Set power_save
function pointer only after this initialization is done
