Syscon register is required in dts to select correct PHY interface.

Is this fixed in mainline Linux too ?
Didn't see this in mainline Linux.
Dinh, do you aware of this? I see sysmgr-syscon error in EMAC in v4.20 kernel.
[ 1.427994] socfpga-dwmac ff800000.ethernet: Could not read reg_offset from sysmgr-syscon! [ 1.436241] socfpga-dwmac ff800000.ethernet: Unable to parse OF data [ 1.442646] socfpga-dwmac: probe of ff800000.ethernet failed with error -22
I see this in mainline Linux:
[ 0.911521] socfpga-dwmac ff800000.ethernet: PTP uses main clock [ 0.917530] socfpga-dwmac ff800000.ethernet: No sysmgr-syscon node found [ 0.924209] socfpga-dwmac ff800000.ethernet: Unable to parse OF data [ 0.930944] stmmaceth ff800000.ethernet: PTP uses main clock [ 0.936723] stmmaceth ff800000.ethernet: User ID: 0x11, Synopsys ID: 0x37 [ 0.943496] stmmaceth ff800000.ethernet: DWMAC1000
It doesn't fail probing though. I'll look into it.
Dinh
Why it probes driver twice? One with "socfpga-dwmac", another with "stmmaceth".
There is error "No sysmgr-syscon node found". So, should we add "sysmgr-syscon" dts parameter to dts?
