| |
Currently the renesas-irqc driver uses postcore_initcall().
However, the new CPG/MSSR driver uses subsys_initcall(). Hence the IRQC's probe will be deferred, which causes the Micrel Ethernet PHY to not find its interrupt on R-Car Gen2 and RZ/G, as the of_mdio subsystem does not support deferred probe yet.
Replace postcore_initcall() by device_initcall() to work around this.
Note that on R-Mobile APE6, where the PFC/GPIO combo uses the IRQC as its parent interrupt controller, this does cause a few additional probe deferrals (for SCIFA0, SD0, SD1, and MMC). But the affected drivers handle that fine.
