Hello Jagan,

To test it with GPIO, I also added this patch to my test bench :

https://patchwork.ozlabs.org/project/uboot/patch/20230213222742.135093-8-macroalpha82@gmail.com/

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 / 
powered down.

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
