From 2108cdcee58b06460a8ecb106d15ab69f5bd49fc Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Wed, 24 Jul 2024 02:55:53 +0200 Subject: [PATCH] drm/panel/panel-ilitek-ili9806e: Add Densitron DMT028VGHMCMI-1D TFT to ILI9806E DSI TCON driver Add Densitron DMT028VGHMCMI-1D 480x640 TFT matrix 2.83 inch panel attached to Ilitek ILI9806E DSI TCON into the ILI9806E driver. Note that the Densitron panels use different TCONs, this driver is for the later panel, use panel-ilitek-st7701.c for the former panel: DMT028VGHMCMI-1A - ST7701 DMT028VGHMCMI-1D - ILI9806E Signed-off-by: Marek Vasut Reviewed-by: Michael Walle Link: https://lore.kernel.org/r/20240724005700.196073-2-marex@denx.de Signed-off-by: Neil Armstrong Link: https://patchwork.freedesktop.org/patch/msgid/20240724005700.196073-2-marex@denx.de --- drivers/gpu/drm/panel/panel-ilitek-ili9806e.c | 165 ++++++++++++++++++ 1 file changed, 165 insertions(+) diff --git a/drivers/gpu/drm/panel/panel-ilitek-ili9806e.c b/drivers/gpu/drm/panel/panel-ilitek-ili9806e.c index e4a44cd26c4d..a3c79ad99d0b 100644 --- a/drivers/gpu/drm/panel/panel-ilitek-ili9806e.c +++ b/drivers/gpu/drm/panel/panel-ilitek-ili9806e.c @@ -380,7 +380,172 @@ static const struct panel_desc com35h3p70ulc_desc = { .lanes = 2, };
