The common Industrial mezzanine overlay already disables the on-board Wi-Fi node. I will move the on-board BT UART/PMU disablement to the same common Industrial mezzanine overlay in v3, so the BT UART overlay only models the reworked M.2 UART wiring. > [...] > >> +&pcie0_m2_e { >> + port { >> + pcie0_m2_e_ep: endpoint { >> + remote-endpoint = <&m2_e_pcie_ep>; >> + }; >> + }; >> +}; >> + >> +&uart4 { >> + interrupts-extended = <&intc GIC_SPI 605 IRQ_TYPE_LEVEL_HIGH>, >> + <&tlmm 19 IRQ_TYPE_EDGE_FALLING>; >> + pinctrl-names = "default", "sleep"; >> + pinctrl-1 = <&qup_uart4_sleep_cts>, <&qup_uart4_sleep_rts>, >> + <&qup_uart4_sleep_tx>, <&qup_uart4_sleep_rx>; >> + >> + status = "okay"; >> + >> + port { >> + uart4_m2_e_ep: endpoint { >> + remote-endpoint = <&m2_e_uart_ep>; >> + }; >> + }; > > Let's define both PCIe and UART endpoint sin the SoC DTSI.

I will move the PCIe and UART graph endpoints to the common SoC DTSI with those generic labels in v3, and keep only the connector-side wiring in the overlay. Thanks, Rahul > Konrad
