2017-08-02mlxsw: spectrum_router: Refresh offload indication upon group refreshIdo Schimmel
Now that we provide offload indication using the nexthop's flags we must refresh the offload indication whenever the offload state within the group changes.

2017-08-02mlxsw: spectrum_router: Don't check state when refreshing offload indicationIdo Schimmel
Previous patch removed the reliance on the counter in the FIB info to set the offload indication, so we no longer need to keep an offload state on each FIB entry and can just set or unset the RTNH_F_OFFLOAD flag in each nexthop. This is also necessary because we're going to need to refresh the offload indication whenever the nexthop group associated with the FIB entry is refreshed. Current check would prevent us from marking a newly resolved nexthop as offloaded if the FIB entry is already marked as offloaded.

2017-08-01ravb: add workaround for clock when resuming with WoL enabledNiklas Söderlund
The renesas-cpg-mssr clock driver are not yet aware of PSCI sleep where power is cut to the SoC. When resuming from this state with WoL enabled the enable count of the ravb clock is 1 and the clock driver thinks the clock is already on when PM core enables the clock and increments the enable count to 2. This will result in the ravb driver failing to talk to the hardware since the module clock is off. Work around this by forcing the enable count to 0 and then back to 2 when resuming with WoL enabled. This workaround should be reverted once the renesas-cpg-mssr clock driver becomes aware of this PSCI sleep behavior.

2017-08-01ravb: add wake-on-lan support via magic packetNiklas Söderlund
WoL is enabled in the suspend callback by setting MagicPacket detection and disabling all interrupts expect MagicPacket. In the resume path the driver needs to reset the hardware to rearm the WoL logic, this prevents the driver from simply restoring the registers and to take advantage of that ravb was not suspended to reduce resume time. To reset the hardware the driver closes the device, sets it in reset mode and reopens the device just like it would do in a normal suspend/resume scenario without WoL enabled, but it both closes and opens the device in the resume callback since the device needs to be reset for WoL to work. One quirk needed for WoL is that the module clock needs to be prevented from being switched off by Runtime PM. To keep the clock alive the suspend callback need to call clk_enable() directly to increase the usage count of the clock. Then when Runtime PM decreases the clock usage count it won't reach 0 and be switched off.

This patch adds the driver for ethernet controller on MT7622 SoC.

So for ease portability and maintenance, those differences all are being kept inside the platform data as other drivers usually do.

Now the call chain cpts_find_ts() |- cpts_fifo_read(cpts, CPTS_EV_PUSH) will stop reading CPTS FIFO if PUSH event is found. But this is not expected and CPTS FIFI should be completely drained here. This is most probably copy-paste error and it has no negative impact as CPTS_EV_PUSH should not be present in FIFO without TS_PUSH request and cpts_systim_read() and cpts_find_ts() synchronized by spin_lock.

2017-08-01net: ethernet: ti: cpts: fix tx timestamping timeoutGrygorii Strashko
With the low speed Ethernet connection CPDMA notification about packet processing can be received before CPTS TX timestamp event, which is set when packet actually left CPSW while cpdma notification is sent when packet pushed in CPSW fifo. As result, when connection is slow and CPU is fast enough TX timestamping is not working properly. Fix it, by introducing TX SKB queue to store PTP SKBs for which Ethernet Transmit Event hasn't been received yet and then re-check this queue with new Ethernet Transmit Events by scheduling CPTS overflow work more often (every 1 jiffies) until TX SKB queue is not empty. Side effect of this change is: - User space tools require to take into account possible delay in TX timestamp processing (for example ptp4l works with tx_timestamp_timeout=400 under net traffic and tx_timestamp_timeout=25 in idle).

There could be significant delay in CPTS work schedule under high system load and on -RT which could cause CPTS misbehavior due to internal counter overflow. Usage of own kthread_worker allows to avoid such kind of issues and makes it possible to tune priority of CPTS kthread_worker thread on -RT (thread name "cpts"). Hence, the CPTS driver is converted to use PTP auxiliary worker as PHC subsystem implements such functionality in a generic way now.
