Subject: [PATCH 11/12] arm64: dts: st: enable display support on stm32mp257f-ev1 board
Date: Fri, 25 Jul 2025 12:04:03 +0200	[thread overview]
Message-ID: <20250725-drm-misc-next-v1-11-a59848e62cf9@foss.st.com> (raw)
In-Reply-To: <20250725-drm-misc-next-v1-0-a59848e62cf9@foss.st.com>

Enable the following IPs on stm32mp257f-ev1 in order to get display:
   * LTDC
   * LVDS
   * WSVGA LVDS panel (1024x600)
   * Panel LVDS backlight as GPIO backlight
   * ILI2511 i2c touchscreen
