Hi, This series add support for the Renesas USBF controller (USB Device Controller) available in the Renesas RZ/N1 SoC. Based on previous iteration: https://lore.kernel.org/lkml/20221213133302.218955-1-herve.codina@xxxxxxxxxxx/ Custom debug macros present in the controller driver source code have been replaced by dev_dbg() calls.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 <robh@xxxxxxxxxx>' Add 'Reviewed-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>' - 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 <geert+renesas@xxxxxxxxx>' - 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 <geert+renesas@xxxxxxxxx>' - 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.
