Subject: [PATCH 0/4] usb: host: renesas: Handle reset signals on suspend/resume

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

Hi,

This series adds handling of reset signals during suspend and resume.
This is necessary for the Renesas RZ/G3S SoC, which has a power-saving
mode that turns off power to most SoC components (including USB).
The reset signals need to be configured accordingly during
suspend and resume.

In addition, a cleanup patch (1/4) has been included.

Thank you,
Claudiu
