2020-09-15pinctrl: Rename sh-pfc to renesasGeert Uytterhoeven
The drivers/pinctrl/sh-pfc subdirectory was originally created to group pin control drivers for various Renesas SuperH and SH-Mobile platforms. However, the name "sh-pfc" no longer reflects its contents, as the directory now contains pin control drivers for Renesas SuperH, ARM32, and ARM64 SoCs. Hence rename the subdirectory from drivers/pinctrl/sh-pfc to drivers/pinctrl/renesas, and the related Kconfig symbol from PINCTRL_SH_PFC to PINCTRL_RENESAS. Rename the git branch in MAINTAINERS, too, for consistency. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Link: https://lore.kernel.org/r/20200909131534.12897-3-geert+renesas@glider.be

2019-12-31pinctrl: sh-pfc: sh7269: Fix CAN function GPIOsGeert Uytterhoeven
pinmux_func_gpios[] contains a hole due to the missing function GPIO definition for the "CTX0&CTX1" signal, which is the logical "AND" of the first two CAN outputs. A closer look reveals other issues: - Some functionality is available on alternative pins, but the PINMUX_DATA() entries is using the wrong marks, - Several configurations are missing. Fix this by: - Renaming CTX0CTX1CTX2_MARK, CRX0CRX1_PJ22_MARK, and CRX0CRX1CRX2_PJ20_MARK to CTX0_CTX1_CTX2_MARK, CRX0_CRX1_PJ22_MARK, resp. CRX0_CRX1_CRX2_PJ20_MARK for consistency with the corresponding enum IDs, - Adding all missing enum IDs and marks, - Use the right (*_PJ2x) variants for alternative pins, - Adding all missing configurations to pinmux_data[], - Adding all missing function GPIO definitions to pinmux_func_gpios[]. See SH7268 Group, SH7269 Group User’s Manual: Hardware, Rev. 2.00: [1] Table 1.4 List of Pins [2] Figure 23.29 Connection Example when Using Channels 0 and 1 as One Channel (64 Mailboxes × 1 Channel) and Channel 2 as One Channel (32 Mailboxes × 1 Channel), [3] Figure 23.30 Connection Example when Using Channels 0, 1, and 2 as One Channel (96 Mailboxes × 1 Channel), [4] Table 48.3 Multiplexed Pins (Port B), [5] Table 48.4 Multiplexed Pins (Port C), [6] Table 48.10 Multiplexed Pins (Port J), [7] Section 48.2.4 Port B Control Registers 0 to 5 (PBCR0 to PBCR5).

2019-04-02pinctrl: sh-pfc: Absorb enum IDs in PINMUX_DATA_REG() macroGeert Uytterhoeven
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.

2018-12-18pinctrl: sh-pfc: sh7269: Add missing PCIOR0 fieldGeert Uytterhoeven
The Port C I/O Register 0 contains 7 reserved bits, but the descriptor contains only dummy configuration values for 6 reserved bits, thus breaking the configuration of all subsequent fields in the register. Fix this by adding the two missing configuration values.

2015-10-20pinctrl: sh-pfc: Rename .gpio_data[] to .pinmux_data[]Geert Uytterhoeven
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".

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

2013-03-15sh-pfc: Replace SoC info data and mark ranges with a number of pinsLaurent Pinchart
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 Pinchart

2013-03-15sh-pfc: Use GPIO_FN instead of PINMUX_GPIO where possibleLaurent Pinchart
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.
