Check BIOS settings

On x86 SOCs, such as sm2s-al or sm2s-el, GPIOs are controlled by the BIOS settings. Thus, depending on these settings, some GPIOs might not be available in the booted system. Additionally some peripherals might be disabled by the BIOS and are not visible in the booted system

Registration required for sm2s-imx95.
