Pin control on the Renesas RZ chips is performed per pin instead of per function (but unfortunately with the various bits of configuration split across a bunch of registers, otherwise we could have used pinctrl-single). This gives us an opportunity to move away from the sh-pfc awful (but more or less needed for the R-Car family) architecture and implement something much, much cleaner without all those obscure data tables and macros, with per-pin configuration. Shouldn't we rejoice and embrace that opportunity ? > Magnus Damm (3): > pinctrl: sh-pfc: Add r7s72100 PFC driver > gpio: gpio-rz: GPIO driver for Renesas RZ series > arm: dts: r7s72100: Add peripherals nodes > > .../bindings/pinctrl/renesas,pfc-pinctrl.txt | 1 + > arch/arm/boot/dts/r7s72100-genmai.dts | 51 ++ > arch/arm/boot/dts/r7s72100.dtsi | 151 ++++++ > drivers/gpio/Kconfig | 6 + > drivers/gpio/Makefile | 1 + > drivers/gpio/gpio-rz.c | 212 +++++++++ > drivers/pinctrl/sh-pfc/Kconfig | 5 + > drivers/pinctrl/sh-pfc/Makefile | 1 + > drivers/pinctrl/sh-pfc/core.c | 9 + > drivers/pinctrl/sh-pfc/pfc-r7s72100.c | 529 ++++++++++++++++++ > drivers/pinctrl/sh-pfc/sh_pfc.h | 9 +- > 11 files changed, 972 insertions(+), 3 deletions(-) > create mode 100644 drivers/gpio/gpio-rz.c > create mode 100644 drivers/pinctrl/sh-pfc/pfc-r7s72100.c -- Regards, Laurent Pinchart
