From: Lin Huang Date: Mon, 2 Jul 2018 10:27:19 +0000 (+0200) Subject: drm/panel: p079zca: Add variable unprepare_delay properties X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=48bd379aa23d0d6249490137e5ebe7f8aeeb887d;p=openwrt%2Fstaging%2Fblogic.git drm/panel: p079zca: Add variable unprepare_delay properties When panel power down, p079zca need delay between reset and disable power supply, but p097pfg does not need it. Similarly p097zca needs a delay after entering panel sleep mode. So add two delay properties, so we can meet these two panel power down sequence.
