* pinctrl: Pass all configs to driver on pin_config_set()Sherman Yin2013-08-2824-726/+952
| | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | This one is missed in commit 42fed7ba "pinctrl: move subsystem mutex to pinctrl_dev struct". I think this fixes the race between pin_free() and pin_request() calls. It protects accessing the members of pctldev->desc. (e.g. update desc->mux_usecount, desc->gpio_owner, desc->mux_owner, etc) Current code grabs pctldev->mutex before calling pinmux_free_gpio(), but did not grab the mutex while calling pinmux_request_gpio().

* gpio: clean up gpio-ranges documentationStephen Warren2013-08-151-25/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change makes documentation of the the gpio-ranges property shorter and more succinct, more consistent with the style of the rest of the document, and not mention Linux-specifics such as the API pinctrl_request_gpio(); DT binding documents should be OS independant where at all possible. As part of this, the gpio-ranges property's format is described in BNF form, in order to match the rest of the document. This change also deprecates the #gpio-range-cells property. Such properties are useful when one node references a second node, and that second node dictates the format of the reference. However, that is not the case here; the definition of gpio-ranges itself always dictates its format entirely, and hence the value #gpio-range-cells must always be 3, and hence there is no point requiring any referenced node to include this property. The only remaining need for this property is to ensure compatibility of DTs with older SW that was written to support the previous version of the binding. v4: * Mention #gpio-range-cells as being deprecated, rather than removing all documentation of that property. This allows DTs to be written in a backwards-compatible way if desired, and also allows older DTs to be interpreted fully using the latest documentation. v3: * Mention BNF in commit description. * Fixed typo. * Dropped patch that removed the deprecated property from *.dts, since it's required to boot older kernels.

* pinctrl: palmas: add pincontrol driverLaxman Dewangan2013-08-145-11/+1216
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | Some of pincontrol driver needs the utility function to create map list. The utility function needed for adding mux, configs etc. In place of duplicating this in each driver, add the common utility function in common file and use from device specific driver. This will reduce the duplicating of code across drivers. Changes from V1: - Add this files in this patch and add common utility APIs to here. Changes from V2: - Nothing in code. - Added Reviewed by Stephen.

If it requests all pins when part of them has already be requested and owned by the 2nd peripheral, this request fails and pinmux_disable_setting() is called. The pinmux_disable_setting() frees all pins of the first peripheral without checking if the pin is owned by itself or the 2nd, which results in the malfunction of the 2nd peripheral driver.
