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 While working on this, I found that for the M4 family, the PCIe reset pin (from the M.2 expansion board) was not wired to the SoC. Only the NanoPC T4 has this wired. This ended up in patches 1 and 3. Patch 1 makes ep_gpio in the Rockchip PCIe driver optional. This property is optional in the DT binding, so this just makes the driver adhere to the binding. Patch 2 adds a new compatible string for the new board. Patch 3 moves the ep-gpios property of the pcie controller from the common nanopi4.dtsi file to the nanopc-t4.dts file. Patch 4 adds a new device tree file for the new board. It includes the original device tree for the M4, and then lists the differences. Given that patch 3 would make PCIe unusable without patch 1, I suggest merging patch 1 through the PCI tree as a fix for 5.10, and the rest for 5.11 through the Rockchip tree. Please have a look. The changes are mostly trivial.
