During development, several lifecycle and resource \nmanagement issues were identified and addressed to satisfy RZ/G2L \nhardware requirements and prevent resource leaks across the driver.\n\nThe series is split into three logical parts to ensure bisectability:\n1. 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 v6:\n- Fixed teardown order in usbhs_udc_otg_remove() to ensure PHY shutdown \n occurs before reset assertion and clock disablement.\n- Added explicit reset_release_bulk() and clk_release_bulk() to both \n the remove path and the probe error paths.\n- Sorted header inclusions alphabetically as requested.\n- Fixed a bug in the clock enable error path where resources were \n not properly released.\n- Carried over the Reviewed-by tags\n\nChanges in v5:\n- Simplified usbhs_probe() signature to only take struct udevice *dev,\n deriving private data internally as requested.\n- Fixed resource leak in usbhs_udc_otg_probe() error paths by adding \n reset_assert_bulk() to the teardown sequence.\n- Standardized resource management by ensuring the probe error path \n perfectly mirrors the removal path.\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\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 | 65 +++++++++++++++++++++++----\n drivers/usb/gadget/rcar/renesas_usb.h | 1 +\n 2 files changed, 58 insertions(+), 8 deletions(-)"}
