struct pin_desc - pin descriptor for each physical pin in the arch : corresponding pin control device datasheet or such : if the name of this pin was dynamically allocated : If zero, the pin is not claimed, and should be NULL. If non-zero, this pin is claimed by . This field is an integer rather than a boolean, since pinctrl_get() might process multiple mapping table entries that refer to, and hence claim, the same group or pin, and each of these will increment the . : The name of device that called pinctrl_get(). : The most recent selected mux setting for this pin, if any. : If pinctrl_request_gpio() was called for this pin, this is the name of the GPIO that "owns" this pin.

Function Documentation

struct pinctrl_dev* get_pinctrl_dev_from_devname ( const char *  devname )

read

get_pinctrl_dev_from_devname() - look up pin controller device : the name of a device instance, as returned by dev_name()

Looks up a pin control device matching a certain device name or pure device pointer, the pure device pointer will take precedence.
