menuconfig PINCTRL
bool "Enable pin controller drivers"
if PINCTRL
config PINCTRL_STORE_REG
bool
help
This option must be selected by drivers that require access to the device
register address. This can happen, for example, if certain pin control
actions are device dependent or require access to device specific
registers
config PINCTRL_NON_STATIC
bool
help
This option can be selected if the pin control configuration defined by
a driver has to be accessed externally. This can happen, for example, when
dynamic pin control is enabled or in testing environments.
