Subject: [PATCH RFT 0/3] usb: renesas_usbhs: Fixes for renesas_usbhs

From: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>

Hi,

Series add fixes for the Renesas USBHS driver identified while
working on the Renesas USB PHY driver (series at [1]).

Series (with [1] on top) was tested on Renesas RZ/G3S with consecutive
unbind/bind and data transfer tests before/after the unbind/bind.

The unbind/bind was also tested on the devices with the following
device trees but w/o checking the data transfer (as I only had
remote access w/o USB devices connected):
- r8a7742-iwg21d-q7.dts
- r8a7743-iwg20d-q7.dts
- r8a7744-iwg20d-q7.dts
- r8a7745-iwg22d-sodimm.dts
- r8a77470-iwg23s-sbc.dts
- r8a774a1-hihope-rzg2m-ex.dts
- r8a774b1-hihope-rzg2n-ex.dts
- r8a774e1-hihope-rzg2h-ex.dts
- r9a07g043u11-smarc.dts
- r9a07g044c2-smarc.dts
- r9a07g044l2-smarc.dts
- r9a07g054l2-smarc.dts
- r9a07g043f01-smarc.dts

Please give it a try also on your devices with [1] on top as well.

Thank you,
Claudiu Beznea
