Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be> As the DTS update has a hard dependency on the driver fix, it has to be postponed until the driver fix has reached mainline. Hence I think it makes sense to apply the DTS update together with the driver fix. Acked-by: Geert Uytterhoeven <geert+renesas@glider.be> Gr{oetje,eeting}s, Geert
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. 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.
