change node name as xhci? prefer to use the same name
Since there are other board manufacturers will use the other HOST ports, like xhci1 or xhci2 with USB mass storage function by their needs. I'll add these 2 node in dtsi in next version.
+ compatible = "mediatek,mt8195-xhci", + "mediatek,mtk-xhci"; + reg = <0 0x112b0000 0 0x1000>, + <0 0x112b3e00 0 0x0100>; + reg-names = "mac", "ippc";
remove "mac"
Will fix it in next version.
Dear Chunfeng,
Unfortunately, if we remove "mac" register here for HOST only node like xhci3, the driver will complain about probing fail. Please check the following log.
=> usb start starting USB... Bus xhci3@112b0000: xhci-mtk xhci3@112b0000: failed to get xHCI base address probe failed, error -6 No working controllers found
I'll add "mac" back to HOST only nodes.
Thanks! Macpaul Lin
