2022-02-22pinctrl: renesas: r8a77990: Share QSPI pin group dataGeert Uytterhoeven1-22/+8
Pin groups qspi[01]_data2 are subsets of qspi[01]_data4. This reduces kernel size by 32 bytes. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Link: https://lore.kernel.org/r/54779df96c1e0fc9ce02786cfd9f66d4cfc063f0.1640269757.git.geert+renesas@glider.be
2022-02-22pinctrl: renesas: Add generic support for resizable busesGeert Uytterhoeven1-98/+86
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.

The "PUEN_" prefixes are part of the bit names of the PUEN registers, while the comments should refer to the actual pin names.

2021-03-24pinctrl: renesas: Move R-Car bias helpers to sh_pfc.hGeert Uytterhoeven1-1/+0
The Renesas Pin Function Controller driver uses two header files: - sh_pfc.h, for use by both core code and SoC-specific drivers, - core.h, for internal use by the core code only. Hence move the R-Car bias helper declarations from core.h to sh_pfc.h, and drop the inclusion of core.h from SoC-specific drivers that no longer need it.

2020-09-15pinctrl: Rename sh-pfc to renesasGeert Uytterhoeven1-0/+5323
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
