2 # Intel pin control drivers
5 config PINCTRL_BAYTRAIL
6 bool "Intel Baytrail GPIO pin control"
7 depends on GPIOLIB && ACPI
10 driver for memory mapped GPIO functionality on Intel Baytrail
11 platforms. Supports 3 banks with 102, 28 and 44 gpios.
12 Most pins are usually muxed to some other functionality by firmware,
