* 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: Pass all configs to driver on pin_config_set()Sherman Yin2013-08-2823-724/+948
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | pinctrl: sunxi: Add Allwinner A20 pins setMaxime Ripard2013-08-232-0/+1019
| | | | | | | | | | | | | | | | | | | | | | 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.
