A bugfix for the gadget deletion sequence during driver remove.\n2. The addition of reset controller infrastructure and proper \n clock/reset teardown logic.\n3. The RZ/G2L specific hardware parameters, SYSCFG logic, and \n compatible strings.\n\nChanges in v4:\n- Split the monolithic patch into a 3-patch series as requested.\n- Added usb_del_gadget_udc() to fix resource leak on driver remove.\n- Implemented bulk reset controller support (required for RZ/G2L).\n- Improved error handling in probe() to ensure clocks are disabled \n if reset initialization or deassertion fails.\n- Moved reset and clock handles to private data to ensure persistence.\n- Reorganized hunks to ensure each patch in the series compiles \n independently (bisectability).\n\nMichele Bisogno (3):\n usb: gadget: rcar: Fix gadget registration lifecycle in remove\n usb: gadget: rcar: Add support for reset controller\n usb: gadget: rcar: Add support for RZ/G2L (R9A07G044)\n\n drivers/usb/gadget/rcar/common.c | 53 ++++++++++++++++++++++++---\n drivers/usb/gadget/rcar/renesas_usb.h | 1 +\n 2 files changed, 48 insertions(+), 6 deletions(-)"}
