Based on previous iteration: https://lore.kernel.org/lkml/20221213133302.218955-1-herve.codina@bootlin.com/ Custom debug macros present in the controller driver source code have been replaced by dev_dbg() calls. Best regards, Herve Codina Changes v4 -> v5: - patch 1 Add 'Reviewed-by: Rob Herring ' Add 'Reviewed-by: Geert Uytterhoeven ' - patch 3 Remove custom TRACE() and TRACEEP() debug macros and use directly dev_dbg() instead. - patch 2, 4 and 5 No changes 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.

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 | 3406 +++++++++++++++++ 7 files changed, 3534 insertions(+) create mode 100644 Documentation/devicetree/bindings/usb/renesas,rzn1-usbf.yaml create mode 100644 drivers/usb/gadget/udc/renesas_usbf.c
