I had changed the device tree and used TFTP to put my customized openwrt on my device. The thing is I have to use LAN1,2,3,4 and SPI as GPIO but it did not determine the names that I used in my device tree. For instance, it gives the error: rt2880-pinmux pinctl: invalid group "spi1". As I used spi1 in my DT.
Firstly, I was wondering if it is possible that I use LAN and SPI as GPIO. Also, I would really appreciate it if you could give me some hints to find the right names for each peripheral that I mentioned. Many thanks.
