Hi, This series adds sleep PM suspend/resume support to the ravb driver. It is based on v4.7 and tested on Salvator-X. I used NFS root filesystem and was able to suspend/resume and keep the system working. I also tested suspend/resume with a initramfs when the interface was down (ifconfig eth0 down) and it was no problems starting after suspend/resume cycle. Note that there is a known issue on Salvator-X where the system will wake up immediately after it have been suspended so the system is not suspended for long. I was not able to test suspend/resume on a Gen2 board due to lack of daugterboard, so if anyone could do that it would be great. Sergei have promised to try and find the time to test it in his 'copious free time' :-) The test procedure is quiet simple: 1. Apply patches 2. Boot and verify network is working 3. Suspend system 'echo mem > /sys/power/state' 4. Wake up system 5. Verify network is still working Niklas Söderlund (2): ravb: use SET_RUNTIME_PM_OPS macro ravb: add sleep PM suspend/resume support drivers/net/ethernet/renesas/ravb_main.c | 75 +++++++++++++++++++++++++++----- 1 file changed, 65 insertions(+), 10 deletions(-) -- 2.9.0
