Based on previous iteration: https://lore.kernel.org/all/20221207162435.1001782-1-herve.codina@bootlin.com/ The 'depends-on' property was removed. Patches 1, 3, 4 and 5 are related to the USBF controller with a new binding definition, the driver itself and myself as a maintainer of this controller. Patch 2 handles h2mode in sysctrl. Hope that this v4 can lead to some feedbacks on the USB device controller itself (patch 3). Best regards, Herve Codina Changes v3 -> v4: - v3 patches 1, 2, 3 and 4 removed - Patch 1 (v3 patch 5) Remove 'depends-on' property - Patch 2 (v3 patch 6) Add 'Reviewed-by: Geert Uytterhoeven ' - Patch 3 (v3 patch 7) Fix warning raised by the kernel test robot - Patch 4 (v3 patch 8) Remove 'depends-on' property add 'Reviewed-by: Geert Uytterhoeven ' - Patch 5 (v3 patch 9) No changes Changes v2 -> v3: - v2 Patches 1, 2 and 3 removed. - Patches 1, 2, 3 and 4 (new patches) - Patch 5 (v2 patch 4): Add 'depends-on' property Removed redundant 'binding' word - Patch 6 (new patch) - Patch 7 (v2 patch 5) Removed h2mode checking. This check is no more needed and the API no more available. - Patch 8 (v2 patch 6) Add 'depends-on' property - Patch 9 (v2 patch 7) Fix file name Changes v1 -> v2: - Patch 1: Rename r9a06g032_sysctrl_get_usb_h2mode to r9a06g032_sysctrl_get_usb_role and return USB_ROLE_{HOST,DEVICE} or an error code. Reword commit log - Patches 2 and 3: No changes. Some previous feedbacks still need to be taken into account https://lore.kernel.org/all/20221107182642.05a09f2f@bootlin.com/ https://lore.kernel.org/all/20221107173614.474707d7@bootlin.com/ - Patch 4: Rename file from renesas,usbf.yaml to renesas,rzn1-usbf.yaml. Remove 'oneOf'. Add blank line and line break. Add 'power-domains'. Reword commit log - Patch 5: Remove clocks handling (handled by runtime PM through the clock domain pointed by power-domains). Fix compilation warning raised by the 'kernel test robot'. - Patch 6: Add 'power-domains' - Patch 7: Add 'Reviewed-by: Geert Uytterhoeven ' Herve Codina (5): dt-bindings: usb: add the Renesas RZ/N1 USBF controller soc: renesas: r9a06g032-sysctrl: Handle h2mode setting based on USBF presence usb: gadget: udc: add Renesas RZ/N1 USBF controller support ARM: dts: r9a06g032: Add the USBF controller node MAINTAINERS: add the Renesas RZ/N1 USBF controller entry .../bindings/usb/renesas,rzn1-usbf.yaml | 68 + MAINTAINERS | 8 + arch/arm/boot/dts/r9a06g032.dtsi | 12 + drivers/clk/renesas/r9a06g032-clocks.c | 28 + drivers/usb/gadget/udc/Kconfig | 11 + drivers/usb/gadget/udc/Makefile | 1 + drivers/usb/gadget/udc/renesas_usbf.c | 3420 +++++++++++++++++ 7 files changed, 3548 insertions(+) create mode 100644 Documentation/devicetree/bindings/usb/renesas,rzn1-usbf.yaml create mode 100644 drivers/usb/gadget/udc/renesas_usbf.c
