2022-02-22pinctrl: renesas: Remove unused pfc parameter from .pin_to_pocctrl()Geert Uytterhoeven1-1/+1
The pfc parameter of the .pin_to_pocctrl() method was never used. It is a relic of the old I/O voltage handling before commit 8775306dcf48092f ("pinctrl: sh-pfc: refactor voltage setting"). Remove the parameter, as it prevents the checker from calling this function for validating consistency of the pin control tables.

2022-02-22pinctrl: renesas: r8a7794: Share SDHI pin group dataGeert Uytterhoeven1-33/+12
Pin groups sdhi[012]_data1 are subsets of sdhi[012]_data4. This reduces kernel size by 24 bytes. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Link: https://lore.kernel.org/r/e4d831e163010d2b62ecc20f8e4b79fd298b2172.1640269757.git.geert+renesas@glider.be
2022-02-22pinctrl: renesas: r8a7794: Share QSPI pin group dataGeert Uytterhoeven1-11/+4
Pin group qspi_data2 is a subset of qspi_data4. This reduces kernel size by 16 bytes. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Link: https://lore.kernel.org/r/114bde1f6e7405f9b299c67f1219adde16ea0212.1640269757.git.geert+renesas@glider.be

Pin groups mmc_data[14] are subsets of mmc_data8. This reduces kernel size by 40 bytes. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Link: https://lore.kernel.org/r/ebeda8834f00ff07799cd6dc36aebae17f378e31.1640269757.git.geert+renesas@glider.be
2022-02-22pinctrl: renesas: Add generic support for resizable busesGeert Uytterhoeven1-63/+55
The VIN_DATA_PIN_GROUP() macro and vin_data{12,16,} unions are used to define multiple VIN data groups with different numbers of lanes, while referring to a single array of data pins, thus saving memory. However, the same feature would be useful for other resizable buses, like MMC, SDHI, QSPI, LCD, BSC, ... Rework the mechanism for generic use: - Use the new SH_PFC_PIN_GROUP_SUBSET() helper to remove the need for bus-specific unions, - Rename VIN_DATA_PIN_GROUP() to BUS_DATA_PIN_GROUP(), - Rename the macro parameters to better reflect their purposes, - Move the macro up, where it belongs. Update all individual pin control drivers for the above changes.

2022-02-22pinctrl: renesas: Rename sh_pfc_soc_operations instancesGeert Uytterhoeven1-3/+3
Some instances of struct sh_pfc_soc_operations are called "<soc>_pfc_ops", others are called "<soc>_pinmux_ops" or just "pinmux_ops". Settle on the first variant, to avoid confusion with "struct pinmux_ops" in the pinctrl core, and to increase consistency.

2022-02-22pinctrl: renesas: r8a7794: Add range checking to .pin_to_pocctrl()Geert Uytterhoeven1-0/+3
The .pin_to_pocctrl() implementation for R-Car E2 does not perform a full range check, unlike on all other SoCs. Add the range check, so the checker can validate better the consistency of the pin control tables.

2021-05-31pinctrl: renesas: r8a7794: Add bias pinconf supportGeert Uytterhoeven1-9/+351
Implement support for pull-up (most pins) and pull-down (ASEBRK#/ACK) handling for R-Car E2 and RZ/G1E SoCs, using the common R-Car bias handling. Note that on RZ/G1E, the "ASEBRK#/ACK" pin is called "ACK", but the code doesn't handle that naming difference. Hence users should use the R-Car naming in DTS files.

2020-09-15pinctrl: Rename sh-pfc to renesasGeert Uytterhoeven1-0/+5644
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
