From 9ca8dbcc65cfc63d6f5ef3312a33184e1d726e00 Mon Sep 17 00:00:00 2001 From: Yunhong Jiang Date: Tue, 4 Aug 2015 12:17:53 -0700 Subject: Add the rt linux 4.1.3-rt3 as base Import the rt linux 4.1.3-rt3 as OPNFV kvm base. It's from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git linux-4.1.y-rt and the base is: commit 0917f823c59692d751951bf5ea699a2d1e2f26a2 Author: Sebastian Andrzej Siewior Date: Sat Jul 25 12:13:34 2015 +0200 Prepare v4.1.3-rt3 Signed-off-by: Sebastian Andrzej Siewior We lose all the git history this way and it's not good. We should apply another opnfv project repo in future.

For each bit + that is set in the cell, the corresponding bit in SCCR will be saved + and cleared on suspend, and restored on resume. This sleep controller + supports disabling and resuming devices at any time. + + fsl,mpc8536-pmc: Sleep specifiers consist of three cells, the third of + which will be ORed into PMCDR upon suspend, and cleared from PMCDR + upon resume. The first two cells are as described for fsl,mpc8578-pmc. + This sleep controller only supports disabling devices during system + sleep, or permanently. + + fsl,mpc8548-pmc: Sleep specifiers consist of one or two cells, the + first of which will be ORed into DEVDISR (and the second into + DEVDISR2, if present -- this cell should be zero or absent if the + hardware does not have DEVDISR2) upon a request for permanent device + disabling.
