| Subject: net: macb: mark device wake capable when "magic-packet" property |
| present |
| |
| From: Nicolas Ferre <nicolas.ferre@microchip.com> |
| |
| [ Upstream commit ced4799d06375929e013eea04ba6908207afabbe ] |
| |
| Change the way the "magic-packet" DT property is handled in the |
| macb_probe() function, matching DT binding documentation. |
| Now we mark the device as "wakeup capable" instead of calling the |
| device_init_wakeup() function that would enable the wakeup source. |
| |
| For Ethernet WoL, enabling the wakeup_source is done by |
| using ethtool and associated macb_set_wol() function that |
| already calls device_set_wakeup_enable() for this purpose. |
| |
| That would reduce power consumption by cutting more clocks if |
| "magic-packet" property is set but WoL is not configured by ethtool. |
| |
