This syncs rk3328 device tree files from the Linux kernel next-20200324. The last commit to touch these files is:
b2411befed60 ("arm64: dts: add bus to rockchip amba nodenames")Additional changes not yet in the Linux kernel include:
arm64: dts: rockchip: rk3328: drop #address-cells, #size-cells from grf node arm64: dts: rockchip: rk3328: drop non-existent gmac2phy pinmux options arm64: dts: rockchip: rk3328: Replace RK805 PMIC node name with "pmic"Changes include:
- conversion of raw pin numbers to macros
- removal of deprecated RK_FUNC_* macros
- update of device tree binding headers
- new devices
- device tree cleanups
- gmac2phy disabled in -u-boot.dtsi as it is not supported in U-boot
This includes a re-ordering of the USB device nodes compared to upstream Linux, moving the dwc2 OTG controller after the EHCI/OHCI nodes. This is currently required as otherwise the dwc2 controller would not be able to detect devices in some cases. This may be due to lack of USB PHY support in U-boot.
Hi Chen-Yu,
Thank you for syncing rk3328 device tree files. On the rock64 with v2020.04 one USB 2.0 port was working (the lower one). Building master now with this merged, no USB ports are working. No power appears to be enabled on them and USB devices are not recognized.
When I was working on v3, it was based on
d202f67db077 Merge branch '2020-04-25-master-imports'
And it was definitely working. My Rock64 is back in its case, so I tested again with the ROC-RK3328-CC just now. All three USB ports work properly, on both the old tree and current master.
Are you using the defconfig, or have you deviated from it? XHCI must be enabled, as VBUS is tied to it (to get everything to work).
ChenYu
Do you have any suggestions for me to try to get them enabled again?
Thanks, -Kurt
