To test it with GPIO, I also added this patch to my test bench :
And then, I was able to test with GPIO : powering up a LED , powering it
down, also tested USB host by having the VBUS powered up by GPIO /
Other pinctrl functions tested were to boot from SD-Card, in which
U-boot sets the right pinfunc for the SD pins.
pinconfig 100 [ + ] pinconfig | |-- sdmmc
pinconfig 101 [ + ] pinconfig | | |-- sdmmc-bus4
pinconfig 102 [ + ] pinconfig | | |-- sdmmc-clk
pinconfig 103 [ + ] pinconfig | | |-- sdmmc-cmd
pinconfig 104 [ + ] pinconfig | | `-- sdmmc-det
pinconfig 132 [ + ] pinconfig | |-- uart2
pinconfig 133 [ + ] pinconfig | | `-- uart2m0-xfer
=> gpio toggle A15
gpio: pin A15 (gpio 15) value is 1
