Message

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.
