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.

2020-11-13pinctrl: renesas: r8a7778: Use common R-Car bias handlingGeert Uytterhoeven1-35/+2
Currently, the rcar_pinmux_[gs]et_bias() helpers handle only SoCs that have separate LSI Pin Pull-Enable (PUEN) and Pull-Up/Down Control (PUD) registers, like R-Car Gen3 and RZ/G2. Update the function to handle SoCs that have only LSI Pin Pull-Up Control Register (PUPR), like R-Car Gen1/Gen2 and RZ/G1. Reduce code duplication by converting the R-Car M1A pin control driver to use the common handler. Note that this changes behavior in case the (invalid!) option "bias-pull-down" is used in an R-Car M1A DTS: before, it was ignored silently; after this change, it is considered the same as "bias-pull-up".

2020-11-13pinctrl: renesas: r8a7778: Use physical addresses for PUPR regsGeert Uytterhoeven1-15/+9
The handling of the LSI Pin Pull-Up Control Registers (PUPR) on R-Car M1A uses register offsets instead of register physical addresses. This is different from the handling on other R-Car parts. Convert the bias handling from register offsets to physical addresses. This increases uniformity, and prepares for consolidation of the bias handling.

2020-09-15pinctrl: Rename sh-pfc to renesasGeert Uytterhoeven1-0/+3185
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
