The standard rule is to do all setup before publishing any device, and socfpga violates that. I can see no reason for this, but these patches have not been tested on hardware. Address this by moving the initialisation of dwmac->stmmac_rst along with all the other dwmac initialisers - there's no reason for this to be late as plat_dat->stmmac_rst has already been populated. Next, replace the call to ops->set_phy_mode() with an init function socfpga_dwmac_init() which will then be linked in to plat_dat->init. Then, add this to plat_dat->init, and switch to stmmac_pltfr_pm_ops from the private ops. The runtime suspend/resume socfpga implementations are identical to the platform ones, but misses the noirq versions which this will add. Before we swap the order of socfpga_dwmac_init() and stmmac_dvr_probe(), we need to change the way the interface is obtained, as that uses driver data and the struct net_device which haven't been initialised. Save a pointer to plat_dat in the socfpga private data, and use that to get the interface mode. We can then swap the order of the init and probe functions. Finally, convert to devm_stmmac_pltfr_probe() by moving the call to ops->set_phy_mode() into an init function appropriately populating plat_dat->init. v2: fix oops when calling set_phy_mode() early. .../net/ethernet/stmicro/stmmac/dwmac-socfpga.c | 79 +++++----------------- 1 file changed, 16 insertions(+), 63 deletions(-) -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 80Mbps down 10Mbps up.
