* pinctrl: make pinctrl_register() return proper error codeMasahiro Yamada2015-06-101-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, pinctrl_register() just returns NULL on error, so the callers can not know the exact reason of the failure. Some of the pinctrl drivers return -EINVAL, some -ENODEV, and some -ENOMEM on error of pinctrl_register(), although the error code might be different from the real cause of the error. This commit reworks pinctrl_register() to return the appropriate error code and modifies all of the pinctrl drivers to use IS_ERR() for the error checking and PTR_ERR() for getting the error code.

* pinctrl: clean up after enable refactoringLinus Walleij2014-09-041-2/+3
| | | | | | | | | | | | | | | | | commit 2243a87d90b42eb38bc281957df3e57c712b5e56 "pinctrl: avoid duplicated calling enable_pinmux_setting for a pin" removed the .disable callback from the struct pinmux_ops, making the .enable() callback the only remaining callback. However .enable() is a bad name as it seems to imply that a muxing can also be disabled. Rename the callback to .set_mux() and also take this opportunity to clean out any remaining mentions of .disable() from the documentation.

| * pinctrl: palmas: do not abort pin configuration for BIAS_DEFAULTLaxman Dewangan2013-09-271-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent movement of all configurations of pin in the single call of pin_config_set(), it is aborting configuration if BIAS_PULL_PIN_DEFAULT is selected as return of configuration. The original idea was to just avoid any update on register for pull up/down configuration if this option is selected. Fixing this by just bypassing any register update for BIAS_PULL_PIN_DEFAULT and continuing the remaining configuration.

* | pinctrl: palmas: remove non-require functionLaxman Dewangan2013-09-271-17/+0
|/ | | | | | | | | | | | | Palmas pinmux and pin configuration support the single pin level configuration in place of pin group. Hence it is only require to pin_config_{set|get} and do not require pin_config_group_{set|get}. As core framework already check for require APIs availability, it is not require to implement as dummy for non-require ops and so removing it.

* pinctrl: Pass all configs to driver on pin_config_set()Sherman Yin2013-08-281-62/+72
| | | | | | | | | | | | | | | | | | | | | When setting pin configuration in the pinctrl framework, pin_config_set() or pin_config_group_set() is called in a loop to set one configuration at a time for the specified pin or group. This patch 1) removes the loop and 2) changes the API to pass the whole pin config array to the driver. It is now up to the driver to loop through the configs. This allows the driver to potentially combine configs and reduce the number of writes to pin config registers. All c files changed have been build-tested to verify the change compiles and that the corresponding .o is successfully generated.

* pinctrl: utils : add support to pass config type in generic util APIsLaxman Dewangan2013-08-231-1/+1
| | | | | | | | | | | | | | | | | | | Add support to pass the config type like GROUP or PIN when using the utils or generic pin configuration APIs. This will make the APIs more generic. Added additional inline APIs such that it can be use directly as callback for the pinctrl_ops. Changes from V1: - Remove separate implementation for pins and group for pinctrl_utils_dt_free_map and improve this function to support both i.e. PINS and GROUPs.

* pinctrl: palmas: add pincontrol driverLaxman Dewangan2013-08-141-0/+1085
TI Palmas series Power Management IC have multiple pins which can be configured for different functionality. This pins can be configured for different function. Also their properties like pull up/down, open drain enable/disable are configurable. Add support for pincontrol driver Palmas series device like TPS65913, TPS80036. The driver supports to be register from DT only. Changes from V1: - Add generic property for pins and functions in pinconf-generic. - Add APIs to map the DT and subnode. - Move common utils APIs to the pinctrl-utils from this file. - Update the binding document accordingly. Changes from V2: - Add ack by Lee. - Correct the binding docs.
