2013-08-23pinctrl: utils : add support to pass config type in generic util APIsLaxman Dewangan
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.

2013-08-23pinctrl: samsung: Parse pin groups before calling pinctrl_register()Tomasz Figa
Calling pinctrl_register() means that the driver is fully initialized and might accept pinmux/pinconf requests, so pin groups must be parsed before. This patch fixes this problem by moving device tree parsing before call to pinctrl_register(). In addition, this fixes support for hogs on pin controllers handled by pinctrl-samsung driver.

The Allwinner A20 is pin-compatible with the older A10, so the two pin set are quite similar. However, since the A20 has new features, we can't just use the A10 pin set as is, and we need to define our own for the A20.

2013-08-16pinctrl: imx: Use struct type for pinsSascha Hauer
The i.MX pinctrl driver uses 5 different arrays for storing the informations for pins. This requires five allocations. Instead, use a struct type which is more cache friendly, readable and requires less allocations. One array of integers is still needed since the pinctrl framework forces us to maintain it. This also adds checks whether the allocations are succesful which were missing.

2013-08-15pinctrl: imx: do not fail when parsing a group failsSascha Hauer
The i.MX pinctrl driver completely bails out when it detects an error in the pinctrl nodes. This usually means that whatever error a devicetree has the user is left blind because even the console cannot be initialized without working pinmux. Instead of bailing out completely, just continue probing. This makes the pinctrl driver work, only the erroneous groups will fail later during pin request time.

pinmux_disable_setting. One peripheral may share part of its pins with the 2nd peripheral and the other pins with the 3rd. 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.

2013-08-07pinctrl: imx: work around select input quirkShawn Guo
The select input for some pin may not be implemented using the regular select input register but the general purpose register. A real example is that imx6q designers found the select input for USB OTG ID pin is missing at the very late stage, and can not add a new select input register but have to use a general purpose register bit to implement it. The patch adds a workaround for such select input quirk by interpreting the input_val cell of pin function ID in a different way, so that all the info that needed for setting up select input bits in general purpose register could be decoded from there.
