pinctrl: Rename sh-pfc to renesas

2020-09-15T08:04:35Z

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 Link: https://lore.kernel.org/r/20200909131534.12897-3-geert+renesas@glider.be

pinctrl: rzn1: Do not select GENERIC_PIN{CTRL_GROUPS,MUX_FUNCTIONS}

2020-09-15T08:04:35Z

The RZ/N1 pin control driver does not use pin groups or pin functions, so there is no need to select GENERIC_PINCTRL_GROUPS or GENERIC_PINMUX_FUNCTIONS. Signed-off-by: Geert Uytterhoeven Link: https://lore.kernel.org/r/20200909131534.12897-2-geert+renesas@glider.be

pinctrl: rza1: Switch to using "output-enable"

2020-09-15T07:37:20Z

For pins requiring software driven IO output operations, the RZ/A1 Pin Controller uses either the "output-high" or "output-low" DT property to enable the corresponding output buffer. The actual line value doesn't matter, as it is ignored. Commit 425562429d4f3b13 ("pinctrl: generic: Add output-enable property") introduced a new DT property for this specific use case. Update the RZ/A1 Pin Controller DT bindings and driver to use this new property instead. Preserve backwards compatibility with old DTBs in the driver, as this comes at a very small cost. Notes: - The DT binding examples already used the new property, - There are no upstream users of the old properties.

pinctrl: sh-pfc: Align driver description title

2020-09-15T07:37:20Z

Now, Renesas Pin Control drivers are under menu, but current descriptions are not aligned. This patch aligns them. - RZ/A2 gpio and pinctrl driver - RZ/N1 pinctrl driver - Emma Mobile EV2 pin control support - R-Mobile APE6 pin control support - R-Mobile A1 pin control support - RZ/G1H pin control support - RZ/G1M pin control support + pin control support for RZ/A2 + pin control support for RZ/N1 + pin control support for Emma Mobile EV2 + pin control support for R-Mobile APE6 + pin control support for R-Mobile A1 + pin control support for RZ/G1H + pin control support for RZ/G1M Signed-off-by: Kuninori Morimoto Link: https://lore.kernel.org/r/87imd8y4r2.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Geert Uytterhoeven

pinctrl: sh-pfc: Collect Renesas related CONFIGs in one place

2020-09-15T07:37:20Z

Renesas related pinctrl CONFIGs are located in many places, which is confusing. This patch collects them into the same place, grouped in a new "Renesas pinctrl drivers" menu. This patch also moves pinctrl-rz{a1,a2,n1}.c into the sh-pfc folder.

2020-07-14T12:57:53Z

Renesas RZ/G2H (r8a774e1) is pin compatible with R-Car H3 (R8A77951), however it doesn't have several automotive specific peripherals. Add automotive-specific pin groups/functions along with common pin groups/functions for supporting both r8a77951 and r8a774e1 SoC.
