The Cannon Lake Windows GPIO driver always exposes 32 pins per "bank"
regardless of whether the hardware actually has that many pins in a pad
group. This means that there are gaps in the GPIO number space even if
such gaps do not exist in the real hardware. To make things worse the
BIOS is also using the same scheme, so for example on Cannon Lake-LP
vGPIO 39 (vSD3_CD_B) the ACPI GpioInt resource has number 231 instead of
the expected 180 (which would be the hardware number).
To make SD card detection and other GPIOs working properly in Linux we
align the pinctrl-cannonlake GPIO numbering to follow the Windows GPIO
driver numbering taking advantage of the gpio_base field introduced in
the previous patch.
