For the NanoPi M4 family, no such signal is routed to the expansion header on the base board. As the schematics for the expansion board were not released, it is unclear how this is handled, but the likely answer is that the signal is always pulled high. Move the ep-gpios property from the common nanopi4.dtsi file to the board level nanopc-t4.dts file. This makes the nanopi-m4 lack ep-gpios, matching the board design. A companion patch "PCI: rockchip: make ep_gpio optional" for the Linux driver is required, as the driver currently requires the property to be present.

The differences against the original Nanopi M4 that are common with the other M4V2 revision include: - microphone header removed - power button added - recovery button added Additional changes specific to the M4B: - USB 3.0 hub removed; board now has 2x USB 3.0 type-A ports and 2x USB 2.0 ports - ADB toggle switch added; this changes the top USB 3.0 host port to a peripheral port - Type-C port no longer supports data or PD - WiFi/Bluetooth combo chip switched to AP6256, which supports BT 5.0 but only 1T1R (down from 2T2R) for WiFi Add a new dts file for the new board revision that shows the difference against the original.
