Hi Fork:
I would like to know whether device tree capable of describing pinmux?
Say, one pin (PIN_10) which can be configured as I2C_SDL, SPI_CLK,
GPIO23,
How can I describe in device tree?
Or, the I2C controller 1 can be configured to use PIN(23, 24) or
PIN(45,46),
What should I should do with device tree?
Thanks
Dennis
