2019-04-02pinctrl: sh-pfc: Absorb enum IDs in PINMUX_DATA_REG() macroGeert Uytterhoeven1-46/+46
Currently the PINMUX_DATA_REG() macro must be followed by initialization data, specifying all enum IDs. Hence the macro itself does not know anything about the enum IDs, preventing the macro from performing any validation on it. Make the macro accept the enum IDs as a parameter, and update all users. Note that array data enclosed by curly braces cannot be passed to a macro as a parameter, hence the enum IDs are wrapped using the GROUP() macro. No functional changes.

2015-10-20pinctrl: sh-pfc: Rename .gpio_data[] to .pinmux_data[]Geert Uytterhoeven1-2/+2
The sh_pfc_soc_info.gpio_data[] array contains not only GPIO data, but also various other pinmux-related data (functions and marks). Every single driver already calls its local array pinmux_data[]. Hence rename the sh_pfc_soc_info member to "pinmux_data".

2013-12-20pinctrl: sh-pfc: sh: Constify pins and cfg_regs arraysLaurent Pinchart1-1/+1
The arrays are never modified, declare them as const. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-07-29sh-pfc: Don't duplicate argument to PINMUX_GPIO macroLaurent Pinchart1-180/+180
The PINMUX_GPIO macro takes a port name and a data mark, respectively of the form GPIO_name and name_DATA. Modify the macro to take the name as a single argument and derive the port name and data mark from it.

2013-07-29sh-pfc: Replace pinmux_enum_id typedef with u16Laurent Pinchart1-1/+1
The typedef only conceals the real variable type without bringing any additional value (see Documentation/CodingStyle, section 5.b). Moreover, it polutes the pinmux namespace. Replace it with the integer type it used to hide. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Tested-by: Yusuke Goda <yusuke.goda.sx@renesas.com>
2013-07-29sh-pfc: sh7724: Remove unused input_pu rangeLaurent Pinchart1-389/+342
The PFC SH7724 SoC data contains a input_pu range used to configure pull-up resistors using the legacy non-pinconf API. That API has been removed from the driver, the range is thus not used anymore. Remove it. If required, configuring pull-up resistors for the SH7724 can be implemented using the pinconf API, as done for the SH-Mobile, R-Mobile and R-Car platforms.

2013-03-15sh-pfc: Split pins and functions definition tablesLaurent Pinchart1-4/+9
Split the GPIOs table into a pins table for real GPIOs and a functions table for function GPIOs. Only register pins with the pinctrl core. The function GPIOs remain accessible as GPIOs.

2013-03-15sh-pfc: Replace SoC info data and mark ranges with a number of pinsLaurent Pinchart1-2/+1
The data and mark ranges are only used to check whether a GPIO corresponds to a real pin or a function. As pins come first in the list of GPIOs and in the platform-specific GPIO enumerations, we can replace the data and mark ranges by a number of pins. Add an nr_pins field to struct sh_pfc_soc_info to store the number of pins implemented by the SoC, remove the data and mark range fields and introduce sh_pfc_gpio_is_pin() and sh_pfc_gpio_is_function() functions to replace range-based checks.

2013-03-15sh-pfc: Replace first_gpio and last_gpio with nr_gpiosLaurent Pinchart1-3/+2
The SoC information first_gpio field is always equal to 0, and the last_gpio field is the index of the last entry in the pinmux_gpios array. Replace the first_gpio and last_gpio fields by a nr_gpios field, and initialize it to ARRAY_SIZE(pinmux_gpios).

2013-03-15sh-pfc: Use GPIO_FN instead of PINMUX_GPIO where possibleLaurent Pinchart1-307/+307
The GPIO_FN macro expands to the PINMUX_GPIO macro. The regular expression to 'unexpand' PINMUX_GPIO to GPIO_FN is s/\tPINMUX_GPIO(GPIO_FN_\([A-Z0-9_]*\),[ \t]*\1_MARK)/\tGPIO_FN(\1)/ This consolidates SoC-specific PFC information to use the same macros for all SoCs.
