Subject: [PATCH 3/3] arm64: dts: ti: k3-j721e-common-proc-board: add assigned clks for DSS
Date: Wed, 22 Apr 2020 12:15:12 +0300 [thread overview]
Message-ID: <20200422091512.950-3-tomi.valkeinen@ti.com> (raw)
In-Reply-To: <20200422091512.950-1-tomi.valkeinen@ti.com>
The DSS related clock muxes are set via assigned-clocks in a way which
provides us:
VP0 - DisplayPort SST
VP1 - DPI0
VP2 - DSI
VP3 - DPI1
