2025-06-02usb: dwc2: Unify flush and reset logic with v4.20a supportKongyang Liu
This patch merges flush and reset logic for both host and gadget code into a common set of functions, reducing duplication. It also adds support for the updated reset logic to compatible with core version since v4.20a. This patch mainly refers to the patch in the kernel. link: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=65dc2e725286106f99c6f6b78e3d9c52c15f3a9c Signed-off-by: Kongyang Liu <seashell11234455@gmail.com> Tested-by: Peter Robinson <pbrobinson@gmail.com> Signed-off-by: Junhui Liu <junhui.liu@pigmoral.tech> Reviewed-by: Mattijs Korpershoek <mkorpershoek@baylibre.com> Reviewed-by: Marek Vasut <marex@denx.de> Link: https://lore.kernel.org/r/20250110-dwc2-dev-v4-7-987f4fd6f8b2@pigmoral.tech Signed-off-by: Mattijs Korpershoek <mkorpershoek@kernel.org>

2025-06-02usb: dwc2: Extract register definitions to common header fileKongyang Liu
The same registers are accessed in both the otg and gatet drivers of dwc2, and these registers are repeatedly defined in these two parts. Extract register definitions into a common header file to reduce redundancy and make the code more maintainable.
