Subject: RE: [PATCH RFC 0/3] Support VBUSEN selection control for RZ/G2L
Date: Mon, 15 Apr 2024 12:18:51 +0000 [thread overview]
Message-ID: <OSAPR01MB1587FA6A68811C80A574BCBE86092@OSAPR01MB1587.jpnprd01.prod.outlook.com> (raw)

Hi All,
What about modelling VBUSEN as a regulator?
USB phy ctrl driver shares the resource to VBUSEN regulator driver
for enable/disable VBUS and PHY driver uses regulator to control the
VBUS??
+ DT as it involves different modelling
Cheers,
Biju
