[PATCH 0/2] Cleanup and fix for NanoPC-T6 Plus

[Diederik de Haas]

Several nodes were enabled/configured when support for the NanoPC-T6 Plus was
added, but later those same nodes got enabled/configured in the dtsi file,
making those in the dts file superfluous, so remove them.

The MTT USB 2.0 Hub is connected to USB20 HOST1, so the phy-supply belongs to
u2phy3_host, not u2phy2_host as that is for USB20 HOST0.

[PATCH 1/2] arm64: dts: rockchip: Drop duplicate USB nodes on NanoPC-T6 LTS

[Diederik de Haas]

Several USB nodes were enabled/configured on the NanoPC-T6 LTS first. Then
those same nodes were enabled/configured in the NanoPC-T6 dtsi file, but
the ones in the LTS dts file were not removed, so do so now.

[PATCH 2/2] arm64: dts: rockchip: Fix USB hub phy-supply config for NanoPC-T6 LTS

[Diederik de Haas]

The MTT USB 2.0 hub is connected to the SoC's USB20 HOST1, so the phy-supply
belongs to u2phy3_host, not u2phy2_host as that is for USB20 HOST0.

Still working on a submission for the NanoPC-T6 Plus ;-)
