Subject: [PATCH v5 0/5] net: macb: Wake-on-Lan magic packet fixes and GEM handling

From: Nicolas Ferre <nicolas.ferre@...rochip.com>

Hi,
Here is a split series to fix WoL magic-packet on the current macb driver. Only
fixes in this one based on current net/master.

Best regards,
  Nicolas

Changes in v5:
- Addressed the error code returned by phylink_ethtool_set_wol() as suggested
  by Russell.
  If PHY handles WoL, MAC doesn't stay in the way.
- Removed Florian's tag on 3/5 because of the above changes.
- Correct the "Fixes" tag on 1/5.

Changes in v4:
- Pure bug fix series for 'net'. GEM addition and MACB update removed: will be
  sent later.

Changes in v3:
- Revert some of the v2 changes done in macb_resume(). Now the resume function
  supports in-depth re-configuration of the controller in order to deal with
  deeper sleep states. Basically as it was before changes introduced by this
  series
- Tested for non-regression with our deeper Power Management mode which cuts
  power to the controller completely

Changes in v2:
- Add patch 4/7 ("net: macb: fix macb_suspend() by removing call to netif_carrier_off()")
  needed for keeping phy state consistent
- Add patch 5/7 ("net: macb: fix call to pm_runtime in the suspend/resume functions") that prevent
  putting the macb in runtime pm suspend mode when WoL is used
- Collect review tags on 3 first patches from Florian: Thanks!
- Review of macb_resume() function
- Addition of pm_wakeup_event() in both MACB and GEM WoL IRQ handlers


Nicolas Ferre (5):
  net: macb: fix wakeup test in runtime suspend/resume routines
  net: macb: mark device wake capable when "magic-packet" property
    present
  net: macb: fix macb_get/set_wol() when moving to phylink
  net: macb: fix macb_suspend() by removing call to netif_carrier_off()
  net: macb: fix call to pm_runtime in the suspend/resume functions
