The USBHS IP found on RZ/G2L SoCs only has 10 pipe buffers compared to 16 pipe buffers on RZ/A2M. Document renesas,rzg2l-usbhs family compatible to handle this difference for RZ/G2L family SoCs. This patch series aims to fix the USB pipe configuration for RZ/G2L family SoCs. For the backward compatibility SoC specific compatible is used and will be removed the same after few kernel releases. As the DTS update has a hard dependency on the driver fix, Got ack from Geert for patch#7 to apply the DTS update together with the driver fix. v2->v3: * Added Rb tag from Geert for patch#1,#2 and #7 * Added Ack tag from Geert for patch#7. * Added patch#3 for improving usbhsc_default_pipe[] for isochronous transfers * Added patch#4 for dropping has_new_pipe_configs from struct renesas_usbhs_driver_param * Updated commit description for patch#5 * Dropped usbhsc_rzg2l_pipe[] and reusing the default_pipe[]. v1->v2: * Added Ack from Krzysztof Kozlowski for patch#1. * Added patch#2 for simplify obtaining device data. * Dropped using of_device_is_compatible() in probe. * Added usbhs_rzg2l_plat_info and replaced the device data for RZ/G2L from usbhs_rza2_plat_info->usbhs_rzg2l_plat_info. * Moved usbhsc_rzg2l_pipe table near to the user. * Updated commit description in patch#3 * Added Rb tag from Geert for patch#4. * Updated commit description about ABI breakage in patch#5. * Updated commit header in patch#5 as it is RZ/G2L specific.
