Openwrt. I set up a custom names for the GPIO pins in the device tree, and start getting system log errors
but I can not find related device in the device tree. Everything is disabled, except console UART.
The pins being named are: 0:18-0:21 (PA18-PA21) , 0:1-0:3 (PA1-PA3), 0:200 (PG8), 0:201 (PG9), 0:64-0:67 (PC0-PC3).
When I start operating PE13 or PE12 I also start receiving errors in the system log, however i2c2 is disabled in the device tree, and there're no external to the CPU devices connected using this interface.
I need all the GPIOs looking outside of the board (why then look outside then and what is the point naming them GPIO on the CPU level). I understand the busses may have something connected to them - but I can not find the source of issues as the busses are disabled (pins are expected to function as GPIOs), and there're no devices in the device tree I get errors for.
Thanks.
