"GPIO-A" through "GPIO-L" are the most important since they give users a handle to look up the standard 96boards GPIOs from the GPIO character device. The rest of the names are more informational, nice debug information for "lsgpio" so you can see that the right line is taken for the right function in the kernel for example.

I'm not sure it even compiles but I think it should look like this with maybe minor tweaks, if you know some of the undefined lines or see some errors feel free to fix it up. --- arch/arm64/boot/dts/hisilicon/hi3660-hikey960.dts | 319 ++++++++++++++++++++++ 1 file changed, 319 insertions(+) diff --git a/arch/arm64/boot/dts/hisilicon/hi3660-hikey960.dts b/arch/arm64/boot/dts/hisilicon/hi3660-hikey960.dts index fd4705c451e2..426e4bcf6803 100644 --- a/arch/arm64/boot/dts/hisilicon/hi3660-hikey960.dts +++ b/arch/arm64/boot/dts/hisilicon/hi3660-hikey960.dts @@ -196,6 +196,325 @@ }; }; +/* + * Legend: proper name = the GPIO line is used as GPIO + * NC = not connected (pin out but not routed from the chip to + * anything the board) + * "[PER]" = pin is muxed for [peripheral] (not GPIO) + * "" = no idea, schematic doesn't say, could be + * unrouted (not connected to any external pin) + * LSEC = Low Speed External Connector + * HSEC = High Speed External Connector + * + * Line names are taken from "HiKey 960 Board ver A" schematics + * from Huawei.
