Subject: [PATCH 2/2] arm64: dts: imx93-phyboard-segin: Add peb-av-02
overlay
From: Andrej Picej <andrej.picej@...ik.com>
Add overlay for Audio-Video module PEB-AV-02. Add support for panel
display, capacitive touchscreen and backlight.
For now the backlight is configured as a GPIO, brightness of the display
can not be set. When the FLEXIO PWM driver is available this should be
switched to PWM backlight driver.
