Subject: [v1 2/2] dt-bindings: drm/panel: boe-tv101wum-nl6: Support enabling a 3.3V rail
Date: Thu, 19 Aug 2021 16:28:43 +0800 [thread overview]
Message-ID: <20210819082843.716986-3-yangcong5@huaqin.corp-partner.google.com> (raw)
In-Reply-To: <20210819082843.716986-1-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.
