I dropped that because the property is only valid for snps,dwmac-{3.50a, 4.10a, 4.20a, 5.20} compatibles, while we have plain snps,dwmac to handle 3.7x. We could have probably used snps,dwmac-3.70a or snps,dwmac-3.710, but I'm not sure which is the exact chip revision and it wouldn't really change anything as there is no special handling for them in the snps,dwmac.yaml binding. >> + status = "disabled"; >> + >> + stmmac_axi_setup: stmmac-axi-config { >> + snps,wr_osr_lmt = <16>; >> + snps,rd_osr_lmt = <16>; >> + snps,blen = <256 128 64 32 0 0 0>; >> + }; >> + }; >> + >> clkgen: clock-controller@11800000 { >> compatible = "starfive,jh7100-clkgen"; >> reg = <0x0 0x11800000 0x0 0x10000>; >> @@ -218,6 +249,11 @@ rstgen: reset-controller@11840000 { >> #reset-cells = <1>; >> }; >> >> + sysmain: syscon@11850000 { >> + compatible = "starfive,jh7100-sysmain", "syscon"; >> + reg = <0x0 0x11850000 0x0 0x10000>; >> + }; >> + >> i2c0: i2c@118b0000 { >> compatible = "snps,designware-i2c"; >> reg = <0x0 0x118b0000 0x0 0x10000>; >> -- >> 2.43.0 >>

I see, makes sense. This way works fine for me. /Emil
