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#6 to apply the DTS update together with the driver
fix.
v4->v5:
* Restored the else path for has_new_pipe_configs check in usbhs_probe().
v3->v4:
* Added Rbtag from Geert for patch#3.
* Dropped patch#4
* Credit Huy Nguyen's work in the commit message for patch#4 and dropped
his name from Signed-off-by tag.
* Selection of usbhsc_rzg2l_default_pipe[] by setting the variable
has_new_pipe_configs to zero.
* Updated commit description for patch#4.
* Dropped the check 'priv->dparam.pipe_configs' as it is same as
checking !has_new_pipe_configs.
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.
