Subject: [PATCH v3 4/4] arm64: dts: sc7180: Support Homestar rev4
Date: Fri, 29 Oct 2021 15:27:43 -0700	[thread overview]
Message-ID: <20211029152647.v3.4.If7aaa8e36f1269acae5488035bd62ce543756bf8@changeid> (raw)
In-Reply-To: <20211029152647.v3.1.Ie17e51ad3eb91d72826ce651ca2786534a360210@changeid>

Support Homestar rev4 board where Parade ps8640 is added as the
second source edp bridge.

Support different edp bridge chips in different board revisions,
now we move the #incldue line of the edp bridge dts fragment (e.g.
sc7180-trogdor-ti-sn65dsi86.dtsi) from "sc7180-trogdor-homestar.dtsi"
to per-board-rev dts files.

Since the edp bridge dts fragment overrides 'dsi0_out', which is
defined in "sc7180.dtsi", move the #incldue line of "sc7180.dtsi" from
"sc7180-trogdor-homestar.dtsi" to per-board-rev dts files too, before
the #include line of the edp bridge dts fragment.
