Subject: Re: [PATCH 4/4] arm64: dts: rockchip: add USB support to RK3308 dts
Date: Fri, 14 May 2021 14:09:45 +0200	[thread overview]
Message-ID: <01388394-603e-6a43-2044-ae1e93eb0ff3@gmail.com> (raw)

Hi Tobias,

Just sent a patch for grf.yaml and rockchip-usb-phy.yaml conversion myself.

Added { .compatible = "rockchip,rk3308-usb2phy", .data =
&rk3308_phy_cfgs }, to phy-rockchip-inno-usb2.c

Added is "rockchip,rk3308-usb-phy" to rockchip-usb-phy.txt

compatible = "rockchip,rk3308-usb2phy"; is used in this patch.

Maybe try phy-rockchip-inno-usb2.yaml?

"rockchip,rk3308-usb2phy-grf", "syscon", "simple-mfd" document missing.

Could someone recheck the reg memory size?
Is this still correct then?

===
compatible = "rockchip,rk3308-grf", "syscon", "simple-mfd";
reg = <0x0 0xff000000 0x0 0x10000>;

Do we still need "0x0 0x10000" here?
===
compatible = "rockchip,rk3308-usb2phy-grf", "syscon", "simple-mfd";
reg = <0x0 0xff008000 0x0 0x4000>;
===
compatible = "rockchip,rk3308-detect-grf", "syscon", "simple-mfd";
reg = <0x0 0xff00b000 0x0 0x1000>;
===
compatible = "rockchip,rk3308-core-grf", "syscon", "simple-mfd";
reg = <0x0 0xff00c000 0x0 0x1000>;
