Huh?

This hunk should be on patch 03/10. Probably some rebase added it here by mistake. I'll fix it on v8. Thanks, Mauro

Sorry missed that. But if these syscon nodes are independent memory regions or belong to non PCI/PHY memory map, you could've fetched the reference through a DT property along with the offset then used it in driver. Like, pcie_phy: pcie-phy@fc000000 { ... hisilicon,noc-power-regs = <&pmctrl 0x38c>; hisilicon,sctrl-cmos-regs = <&sctrl 0x60>; ... }; The benefit of doing this way is, if the pmctrl, sctrl register layout changes in future, you can handle it without any issues. > > > > > > iomcu: iomcu@ffd7e000 { > > > compatible = "hisilicon,hi3670-iomcu", "syscon"; > > > reg = <0x0 0xffd7e000 0x0 0x1000>; > > > @@ -660,6 +666,71 @@ gpio28: gpio@fff1d000 { > > > clock-names = "apb_pclk"; > > > }; > > > > > > > [...] > > > > > + #interrupt-cells = <1>; > > > + interrupts = <0 283 4>; > > > > Use the DT flag for interrupts instead of hardcoded value > > Do you mean like this? > > interrupts = <0 283 IRQ_TYPE_LEVEL_HIGH>; > yes but you could also use, interrupts = <GIC_SPI 283 IRQ_TYPE_LEVEL_HIGH>; Thanks, Mani

Interesting approach, but probably overkill. I mean, the register mapping here should be the same for all Kirin 970 PHY based devices. A PHY for a different SoC will likely have other differences than just those two regs. Regards, Mauro
