[PATCH v2 8/9] arm64: dts: st: Add USB nodes on stm32mp231
From: Marek Vasut
Date: Sun Aug 16 2026 - 17:40:52 EST
Add USB controller and PHY nodes to stm32mp231 DT.
This includes two USB 2.0 FEMTO PHYs, USB 2.0 host
controller and DWC3 DRD controller nodes. Include
missing COMBOPHY for the USB 3.0 controller.

V2: - Fix up Sob/Cdb lines
- Move PHY into syscfg subnode
- Turn st,stm32mp23-syscfg into simple-mfd
- Use clock-cells = <1> to discern OSC and future PLL clock from the PHY
