Subject: [PATCH v3 1/6] dt-bindings: mediatek,dpintf: Add DP_INTF binding
Date: Fri, 1 Oct 2021 11:44:38 +0200 [thread overview]
Message-ID: <20211001094443.2770169-2-msp@baylibre.com> (raw)
In-Reply-To: <20211001094443.2770169-1-msp@baylibre.com>
DP_INTF is a similar functional block to mediatek,dpi but is different
in that it serves the DisplayPort controller on mediatek SoCs and uses
different clocks. Therefore this patch creates a new binding file for
this functional block.
Signed-off-by: Markus Schneider-Pargmann <msp@baylibre.com>

Notes:
Changes v1 -> v2:
- Move the devicetree binding from mediatek,dpi into its own binding file.
