3  * Core private header for the pin control subsystem
30  * struct pinctrl_dev - pin control class device
31  * @node: node to include this pin controller in the global pin controller list
32  * @desc: the pin controller descriptor supplied when initializing this pin
34  * @pin_desc_tree: each pin descriptor for this pin controller is stored in
36  * @pin_group_tree: optionally each pin group can be stored in this radix tree
40  * @gpio_ranges: a list of GPIO ranges that is handled by this pin controller,
42  * @dev: the device entry for this pin controller
43  * @owner: module providing the pin controller, used for refcounting
44  * @driver_data: driver data for drivers registering to the pin controller
49  * @mutex: mutex taken on each pin controller specific action
78  * struct pinctrl - per-device pin control state holder
80  * @dev: the device using this pin control handle
120  * @group_or_pin: the group selector or pin ID to program
122  *	hardware. Each individual pin controller defines the format and meaning
136  * @pctldev: pin control device handling to be programmed. Not used for
153  * struct pin_desc - pin descriptor for each physical pin in the arch
154  * @pctldev: corresponding pin control device
155  * @name: a name for the pin, e.g. the name of the pin/pad/finger on a
157  * @dynamic_name: if the name of this pin was dynamically allocated
158  * @drv_data: driver-defined per-pin data. pinctrl core does not touch this
159  * @mux_usecount: If zero, the pin is not claimed, and @owner should be NULL.
160  *	If non-zero, this pin is claimed by @owner. This field is an integer
163  *	or pin, and each of these will increment the @usecount.
165  * @mux_setting: The most recent selected mux setting for this pin, if any.
166  * @gpio_owner: If pinctrl_gpio_request() was called for this pin, this is
167  *	the name of the GPIO that "owns" this pin.
200  * struct group_desc - generic pin group descriptor
201  * @grp: generic data of the pin group (name and pins)
202  * @data: pin controller driver specific data
