Subject: [RFC PATCH 8/8] arm64: dts: qcom: sc7180: trogdor devices can use probable eDP panels
Date: Thu, 22 Jul 2021 17:21:46 -0700 [thread overview]
Message-ID: <20210722172104.RFC.8.I038959fe65a202bd513cebeeffc7309114b5ffde@changeid> (raw)
In-Reply-To: <20210723002146.1962910-1-dianders@chromium.org>
This change enables probable eDP panels for all sc7180-trogdor
variants, leaving the existing panel as a fallback.
Though this won't make any immediate change, it paves the way for
supporting more second source panels on trogdor devices. It also
removes a "little white lie" which is that some trogdor devices
already had second sources for their panels but the panels were
compatible enough that they could simply use the same delays across
the board.
NOTE that all trogdor devices currently supported by mainline have HPD
hooked up properly and so there is no need for the hpd-absent-delay on
any of these. One of the trogdor devices does have a glitchy HPD upon
first power on, though, so we need "hpd-reliable-delay" on lazor.
This also removes the "innolux,n116bge" fallback from one of the
limozeen models. The limozeen board never had this panel but the
"innolux,n116bge" panel timings / delays worked OK and having this as
a fallback compatible string helped until the "innolux,n116bca-ea1"
panel was supported.
