2023-05-09pinctrl: renesas: Fix spaces followed by tabsMarek Vasut1-3/+3
Perform 's@ \t@\t\t@g' so we wouldn't have spaces followed by tabs. No functional change. Picked from U-Boot commit 0cf207ec01c ("WS cleanup: remove SPACE(s) followed by TAB") Signed-off-by: Marek Vasut <marek.vasut+renesas@mailbox.org> Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> Link: https://lore.kernel.org/r/20230507130120.7587-1-marek.vasut+renesas@mailbox.org Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
2023-03-30pinctrl: renesas: Annotate sentinels in tablesGeert Uytterhoeven1-2/+2
It does not make sense to have a comma after a sentinel, as any new elements must be added before the sentinel. Hence drop all such commas. Add comments to clarify the purpose of the empty elements.

2023-03-30pinctrl: renesas: r8a77980: Add support for AVB/GE power-sourcesGeert Uytterhoeven1-11/+28
Add support for configuring the I/O voltage levels of the Ethernet AVB and Gigabit Ethernet pins on the R-Car V3H SoC. "PIN_VDDQ_AVB" and "PIN_VDDQ_GE" can be configured for 2.5V or 3.3V operation.

2023-03-30pinctrl: renesas: rcar: Phase out old SH_PFC_PIN_CFG_IO_VOLTAGE flagGeert Uytterhoeven1-3/+3
Commit 537db25ca330dce0 ("pinctrl: renesas: Add I/O voltage level flag") introduced new flags to support pins that can switch their voltage levels between either 1.8V and 3.3V, or between 2.5V and 3.3V. The old SH_PFC_PIN_CFG_IO_VOLTAGE flag was retained to avoid having to change existing drivers. Replace SH_PFC_PIN_CFG_IO_VOLTAGE by SH_PFC_PIN_CFG_IO_VOLTAGE_18_33, to make the voltage configuration explicit, and to prepare for the advent of support for more voltage levels.

2022-05-05pinctrl: renesas: r8a77980: Optimize fixed-width reserved fieldsGeert Uytterhoeven1-63/+28
Describe registers with fixed-width register fields and many reserved fields using the PINMUX_CFG_REG_VAR() macro, as the latter supports a shorthand not requiring dummy values. This reduces kernel size by 198 bytes.

Replace the full descriptions of reserved register fields by shorthands with a negative field width, and merge adjacent reserved fields. This reduces kernel size by 168 bytes.

2022-02-22pinctrl: renesas: Remove unused pfc parameter from .pin_to_pocctrl()Geert Uytterhoeven1-2/+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.

Pin groups qspi[01]_data[24] are subsets of rpc_data. Pin group rpc_clk1 is a subset of rpc_clk2. This reduces kernel size by 104 bytes.

2022-02-22pinctrl: renesas: Add generic support for resizable busesGeert Uytterhoeven1-57/+49
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 Uytterhoeven1-2/+2
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.

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/+2972
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
