Subject: [RESEND PATCH v2 2/6] usb: typec: add typec_find_pwr_opmode
Date: Wed, 2 Sep 2020 09:57:03 +0200 [thread overview]
Message-ID: <20200902075707.9052-3-amelie.delaunay@st.com> (raw)
In-Reply-To: <20200902075707.9052-1-amelie.delaunay@st.com>
This patch adds a function that converts power operation mode string into
power operation mode value.
It is useful to configure power operation mode through device tree
property, as power capabilities may be linked to hardware design.
