Subject: [v4 2/4] dt-bindings: drm/panel: boe-tv101wum-nl6: Support enabling a 3.3V rail
Date: Mon, 30 Aug 2021 10:38:47 +0800 [thread overview]
Message-ID: <20210830023849.258839-3-yangcong5@huaqin.corp-partner.google.com> (raw)
In-Reply-To: <20210830023849.258839-1-yangcong5@huaqin.corp-partner.google.com>
The auo,b101uan08.3 panel (already supported by this driver) has
a 3.3V rail that needs to be turned on. For previous users of
this panel this voltage was directly output by pmic. On a new
user (the not-yet-upstream sc7180-trogdor-mrbland board) we need
to turn the 3.3V rail on.
