From 482543590fc9d405697b01b1b11af8a97ffd553a Mon Sep 17 00:00:00 2001 From: Dario Binacchi Date: Wed, 8 Nov 2023 14:44:06 +0100 Subject: [PATCH] ARM: dts: stm32: use the same 3v3 for SD and DSI nodes on stm32f469-disco In the board schematic, the power supply for the SD card is the same 3.3 volts used to power the LCD panel and other peripherals. By generalizing the name of the voltage regulator, it simplifies the device tree and makes it more readable.
