2014-01-09sh-pfc: Fix PINMUX_GPIO macroLaurent Pinchart
commit 8620f394c4f9abd13e4fdf927d9c2bbeda74cde7 upstream. Commit 7cbb0e55e27e ("sh-pfc: Don't duplicate argument to PINMUX_GPIO macro") erronesouly modified the PINMUX_GPIO macro in a way that resulted in all pins being named "name". Fix the macro to name the pins correctly.

2013-08-28pinctrl: sh-pfc: remove unnecessary platform_set_drvdata()Jingoo Han
The driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL.

2013-08-28pinctrl: Pass all configs to driver on pin_config_set()Sherman Yin
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.

2013-07-29sh-pfc: Support pins not associated with a GPIO portLaurent Pinchart
Pins with selectable functions but without a GPIO port can't be named PORT_# or GP_#_#. Add a SH_PFC_PIN_NAMED macro to declare such pins in the pinmux pins array, naming them with the PIN_ prefix followed by the pin physical position. In order to make sure not to register those pins as GPIOs, add a SH_PFC_PIN_CFG_NO_GPIO pin flag to denote pins without a GPIO port.

2013-07-29sh-pfc: Replace pinmux_enum_id typedef with u16Laurent Pinchart

2013-07-29sh-pfc: Don't overallocate memory for the GPIO chip pins arrayLaurent Pinchart
The GPIO driver uses an array of sh_pfc_gpio_pin structures to store per-GPIO pin data. The array size is miscomputed at allocation time by using the number of the last pin instead of the number of pins. When the pin space contains holes this leads to memory overallocation. Fix it.
