Subject: [PATCH v5 7/7] ARM: dts: ti: cpcap-mapphone: add USB safe pinctrl state
Date: Sat, 11 Jul 2026 23:42:10 +0300 [thread overview]
Message-ID: <20260711204210.197144-8-ivo.g.dimitrov.75@gmail.com> (raw)
In-Reply-To: <20260711204210.197144-1-ivo.g.dimitrov.75@gmail.com>
Add a pinctrl state that configures the USB interface pins into a safe
GPIO configuration. This allows the CPCAP USB PHY driver to place the
pins into a defined state whenever the USB interface is not active.
