* @PIN_CONFIG_INPUT_DEBOUNCE: this will configure the pin to debounce mode,
|
||||
* which means it will wait for signals to settle when reading inputs. The
|

* argument gives the debounce time in usecs. Setting the
|
||||
* argument to zero turns debouncing off.

* @PIN_CONFIG_POWER_SOURCE: if the pin can select between different power
|

* supplies, the argument to this parameter (on a custom format) tells

* the driver which alternative power source to use.
|

* @PIN_CONFIG_SLEW_RATE: if the pin can select slew rate, the argument to
|

* this parameter (on a custom format) tells the driver which alternative

* slew rate to use.

* @PIN_CONFIG_LOW_POWER_MODE: this will configure the pin for low power
|
||||
* operation, if several modes of operation are supported these can be
|
||||
* passed in the argument on a custom form, else just use argument 1
|
||||
* to indicate low power mode, argument 0 turns low power mode off.
|
||||
* @PIN_CONFIG_OUTPUT: this will configure the pin as an output. Use argument
|
||||
* 1 to indicate high level, argument 0 to indicate low level. (Please
|
||||
* see Documentation/pinctrl.txt, section "GPIO mode pitfalls" for a
|
||||
* discussion around this parameter.)
|
||||
* @PIN_CONFIG_OUTPUT_ENABLE: this will enable the pin's output mode
|
||||
* without driving a value there. For most platforms this reduces to
|
||||
* enable the output buffers and then let the pin controller current
|
||||
* configuration (eg. the currently selected mux function) drive values on
|
||||
* the line. Use argument 1 to enable output mode, argument 0 to disable
|
||||
* it.
|
||||
* @PIN_CONFIG_OUTPUT: this will configure the pin as an output and drive a
|
||||
* value on the line. Use argument 1 to indicate high level, argument 0 to
|
||||
* indicate low level. (Please see Documentation/driver-api/pinctl.rst,
|
||||
* section "GPIO mode pitfalls" for a discussion around this parameter.)
|
||||
* @PIN_CONFIG_POWER_SOURCE: if the pin can select between different power
|
||||
* supplies, the argument to this parameter (on a custom format) tells
|
||||
* the driver which alternative power source to use.
|
||||
* @PIN_CONFIG_SLEEP_HARDWARE_STATE: indicate this is sleep related state.
|
||||
* @PIN_CONFIG_SLEW_RATE: if the pin can select slew rate, the argument to
|
||||
* this parameter (on a custom format) tells the driver which alternative
|
||||
* slew rate to use.
|
||||
* @PIN_CONFIG_SKEW_DELAY: if the pin has programmable skew rate (on inputs)
|
||||
* or latch delay (on outputs) this parameter (in a custom format)
|
||||
* specifies the clock skew or latch delay. It typically controls how
|
||||
* many double inverters are put in front of the line.
|
||||
* @PIN_CONFIG_END: this is the last enumerator for pin configurations, if
|
||||
* you need to pass in custom configurations to the pin controller, use
|
||||
* PIN_CONFIG_END+1 as the base offset.
|
||||
* @PIN_CONFIG_MAX: this is the maximum configuration value that can be
|
||||
* presented using the packed format.
