These\n  are now just state transitions.\n- Delete slew rate rising/falling due to discussions on on\n  proper semantics\n- Drop config wakeup, struct irq_chip does this for now, add\n  back if need be.\n- Set PIN_CONFIG_END to 0x7fff making room for custom config\n  parameters from 0x8000 and up.\n- Prefix accessor functions with pinconf_\n"

      "message": "pinctrl: add a pin config interface\n\nThis add per-pin and per-group pin config interfaces for biasing,\ndriving and other such electronic properties. The details of passed\nconfigurations are passed in an opaque unsigned long which may be\ndereferences to integer types, structs or lists on either side\nof the configuration interface.\n\nChangeLog v1-\u003ev2:\n- Clear split of terminology: we now have pin controllers, and\n  those may support two interfaces using vtables: pin\n  multiplexing and pin configuration.\n- Break out pin configuration to its own C file, controllers may\n  implement only config without mux, and vice versa, so keep each\n  sub-functionality of pin controllers separate. Introduce\n  CONFIG_PINCONF in Kconfig.\n- Implement some core logic around pin configuration in the\n  pinconf.c file.\n- Remove UNKNOWN config states, these were just surplus baggage.\n- Remove FLOAT config state - HIGH_IMPEDANCE should be enough for\n  everyone.\n- PIN_CONFIG_POWER_SOURCE added to handle switching the power\n  supply for the pin logic between different sources\n- Explicit DISABLE config enums to turn schmitt-trigger,\n  wakeup etc OFF.\n- Update documentation to reflect all the recent reasoning.\nChangeLog v2-\u003ev3:\n- Twist API around to pass around arrays of config tuples instead\n  of (param, value) pairs everywhere.\n- Explicit drive strength semantics for push/pull and similar\n  drive modes, this shall be the number of drive stages vs\n  nominal load impedance, which should match the actual\n  electronics used in push/pull CMOS or TTY totempoles.\n- Drop load capacitance configuration - I probably don\u0027t know\n  what I\u0027m doing here so leave it out.\n- Drop PIN_CONFIG_INPUT_SCHMITT_OFF, instead the argument zero to\n  PIN_CONFIG_INPUT_SCHMITT turns schmitt trigger off.\n- Drop PIN_CONFIG_NORMAL_POWER_MODE and have a well defined\n  argument to PIN_CONFIG_LOW_POWER_MODE to get out of it instead.\n- Drop PIN_CONFIG_WAKEUP_ENABLE/DISABLE and just use\n  PIN_CONFIG_WAKEUP with defined value zero to turn wakeup off.\n- Add PIN_CONFIG_INPUT_DEBOUNCE for configuring debounce time\n  on input lines.\n- Fix a bug when we tried to configure pins for pin controllers\n  without pinconf support.\n- Initialized debugfs properly so it works.\n- Initialize the mutex properly and lock around config tampering\n  sections.\n- Check the return value from get_initial_config() properly.\nChangeLog v3-\u003ev4:\n- Export the pin_config_get(), pin_config_set() and\n  pin_config_group() functions.\n- Drop the entire concept of just getting initial config and\n  keeping track of pin states internally, instead ask the pins\n  what state they are in. Previous idea was plain wrong, if the\n  device cannot keep track of its state, the driver should do\n  it.\n- Drop the generic configuration layout, it seems this impose\n  too much restriction on some pin controllers, so let them do\n  things the way they want and split off support for generic\n  config as an optional add-on.\nChangeLog v4-\u003ev5:\n- Introduce two symmetric driver calls for group configuration,\n  .pin_config_group_[get|set] and corresponding external calls.\n- Remove generic semantic meanings of return values from config\n  calls, these belong in the generic config patch. Just pass the\n  return value through instead.\n- Add a debugfs entry \"pinconf-groups\" to read status from group\n  configuration only, also slam in a per-group debug callback in\n  the pinconf_ops so custom drivers can display something\n  meaningful for their pins.\n- Fix some dangling newline.\n- Drop dangling #else clause.\n- Update documentation to match the above.\nChangeLog v5-\u003ev6:\n- Change to using a pin name as parameter for the\n  [get|set]_config() functions, as suggested by Stephen Warren.\n  This is more natural as names will be what a developer has\n  access to in written documentation etc.\nChangeLog v6-\u003ev7:\n- Refactor out by-pin and by-name get/set functions, only expose\n  the by-name functions externally, expose the by-pin functions\n  internally.\n- Show supported pin control functionality in the debugfs\n  pinctrl-devices file.\n\nAcked-by: Stephen Warren \u003cswarren@nvidia.com\u003e\nSigned-off-by: Linus Walleij \u003clinus.walleij@linaro.org\u003e\n"
