[PATCH v2 2/2] arm64: dts: rockchip: fix PCIe regulator name on NanoPC-T6

From: Ricardo Pardini via B4 Relay

Date: Fri May 29 2026 - 11:57:38 EST


From: Ricardo Pardini <ricardo@xxxxxxxxxxx>

The GPIO-switched 3v3 regulator on the NanoPC-T6 is labeled
vcc3v3_pcie2x1l0, but it is wired to and consumed by &pcie2x1l1, and
its enable is the pcie_m2_1_pwren pin - i.e. it powers the M.2 slot on
pcie2x1l1, not pcie2x1l0. The two soldered RTL8125 NICs on pcie2x1l0
and pcie2x1l2 instead share the always-on vcc_3v3_pcie20 rail, so
nothing actually uses an "l0" switched supply.

Rename the label, node name and regulator-name to vcc3v3_pcie2x1l1 so
they match the controller the rail actually supplies.
