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
2019-06-04pinctrl: sh-pfc: sh73a0: Use new macros for non-GPIO pinsGeert Uytterhoeven
Update the SH-Mobile AG5 pin control driver to use the new macros for describing pins without GPIO functionality. This replaces the use of physical pin numbers on the SH-Mobile AG5 SoC (in 34x34 BGA package) by symbolic enum values, referring to signal names. Note that the user-visible names of these pins are still based on pin numbers instead of signal names, to preserve DT backwards compatibility.

2019-05-21pinctrl: sh-pfc: Add SH_PFC_PIN_CFG_PULL_UP_DOWN shorthandGeert Uytterhoeven
It is very common for a pin to support both pull-up and pull-down functionality. Hence add a shorthand SH_PFC_PIN_CFG_PULL_UP_DOWN. This not only reduces typing, but also avoids the need for several line breaks, and makes many overly long lines shorter, improving readability.

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.

The sh73a0 has an internal power gate on the VCCQ power supply for the SDHI0 device that is controlled (for some strange reason) by a bit in a PFC register. This feature should be exposed as a regulator. As the same register is also used for pin control purposes there is no way to achieve atomic read/write sequences with a separate regulator driver.

2013-03-18ARM: shmobile: INTC External IRQ pin driver on sh73a0Magnus Damm
Adjust the sh73a0 IRQ code to make use of the INTC External IRQ pin driver for external interrupt pins IRQ0 -> IRQ31. This removes quite a bit of special-case code in intc-sh73a0.c but the number of lines get replaced with platform device information in setup-sh73a0.c. The PFC code is also adjusted to make gpio_to_irq() return the correct interrupt number. At this point the DT reference implementations are not covered. In the future such code shall tie in the INTC External IRQ pin driver via DT, so this kind of verbose code is not needed for the long term DT case.
