The output pins of the general PWM timer (GPT) can be disabled by using the port output enabling function for the GPT (POEG). Specifically, either of the following ways can be used. * Input level detection of the GTETRGA to GTETRGD pins. * Output-disable request from the GPT. * Register settings. This patch series add support for controlling output disable function using sysfs. For output disable operation, POEG group needs to be linked with GPT. Plan to send a follow up patch with renesas,poeg-group as numeric property in pwm bindings for linking both GPT and POEG devices. REF->v1: * Modelled as pincontrol as most of its configuration is intended to be static and moved driver files from soc to pincontrol directory. * Updated reg size in dt binding example. * Updated Kconfig REF: https://lore.kernel.org/linux-renesas-soc/20220510151112.16249-1-biju.das.jz@xxxxxxxxxxxxxx/ Biju Das (2): dt-bindings: pinctrl: renesas: Add RZ/G2L POEG binding drivers: pinctrl: renesas: Add POEG driver support .../bindings/pinctrl/renesas,rzg2l-poeg.yaml | 65 ++++++++ drivers/pinctrl/renesas/Kconfig | 2 + drivers/pinctrl/renesas/Makefile | 2 + drivers/pinctrl/renesas/poeg/Kconfig | 12 ++ drivers/pinctrl/renesas/poeg/Makefile | 2 + drivers/pinctrl/renesas/poeg/poeg-rzg2l.c | 147 ++++++++++++++++++ 6 files changed, 230 insertions(+) create mode 100644 Documentation/devicetree/bindings/pinctrl/renesas,rzg2l-poeg.yaml create mode 100644 drivers/pinctrl/renesas/poeg/Kconfig create mode 100644 drivers/pinctrl/renesas/poeg/Makefile create mode 100644 drivers/pinctrl/renesas/poeg/poeg-rzg2l.c -- 2.25.1
