Subject: [PATCH] drm: mxsfb: Implement drm_panel handling
Date: Wed, 1 Feb 2017 15:19:47 -0200 [thread overview]
Message-ID: <1485969587-3630-1-git-send-email-fabio.estevam@nxp.com> (raw)
Currently when the 'power-supply' regulator is passed via device tree
it does not actually work since drm_panel_prepare()/drm_panel_enable()
are never called.
Quoting Thierry Reding: "It should really call drm_panel_prepare() and
drm_panel_enable() while switching on the display pipeline and
drm_panel_disable(), followed by drm_panel_unprepare() while switching
off the display pipeline."
So do as suggested, so that the 'power-supply' regulator can be functional.
