We followed the instructions to install the pinctrl driver, but it doesn't work, we can't contorl the LEDs, GPIOs are not available, nor spi or uart.
Dmesg we see this problem:

I also updated the BIOS to 1.7, reinstalled ubuntu 20.04 (5.4.0-144-generic) and pinctrl driver, and still can't access the pins
