Subject: [PATCH RFC 0/3] Support VBUSEN selection control for RZ/G2L
Date: Thu, 18 May 2023 16:56:46 +0100 [thread overview]
Message-ID: <20230518155649.516346-1-biju.das.jz@bp.renesas.com> (raw)
This patch series aims to add support for VBUSEN selection control for
RZ/G2L alike SoCs.
As per RZ/G2L HW(Rev.1.30 May2023) manual, VBUSEN can be controlled by
the Port Power bit of the EHCI/OHCI operational register or by the VBOUT
bit of the VBUS Control Register.
A reset consumer(phy-rcar-gen3-usb2) needs to find the reset controller
device and then call the provider(reset-rzg2l-usbphy-ctrl) to configure
it.
Please share your thoughts on this patch series.
