Subject: [PATCH AUTOSEL 6.13 23/37] drm/mediatek: mtk_dpi: Move the input_2p_en bit to platform data
Date: Thu,  3 Apr 2025 15:14:59 -0400	[thread overview]
Message-ID: <20250403191513.2680235-23-sashal@kernel.org> (raw)
In-Reply-To: <20250403191513.2680235-1-sashal@kernel.org>

From: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>

[ Upstream commit c90876a695dd83e76680b88b40067275a5982811 ]

In preparation for adding support for MT8195's HDMI reserved DPI
instance, move the input_2p_en bit for DP_INTF to platform data.

While at it, remove the input_2pixel member from platform data as
having this bit implies that the 2pixel feature must be enabled.
