Subject: [PATCH v2 0/3] ARM: dts: stm32: Fix STM32MP1 ev and dk USB onboard HUB supplies
Date: Fri, 21 Aug 2026 16:57:37 +0200 [thread overview]
Message-ID: <20260821-usb_fixes_vdda-v1-v2-0-23cc919b59fb@foss.st.com> (raw)
Some STM32 boards use Microchip USB2514 HUB. Since vdda supply has been
added, the regulator framework wrongly associates the 'vdda' supply
dedicated to ADC, so the wrong regulator is referenced.
Only the 3v3 regulator is used to supply both the digital and the analog
part of the HUB.
Before this series:
cat /sys/kernel/debug/regulator/regulator_summary
...
v3v3 10 9 0 normal 3300mV 0mA 3300mV 3300mV
...
5800d000.usb:hub@1-vdd 1 0mA 0mV 0mV
...
vdda 1 1 0 unknown 2900mV 0mA 2900mV 2900mV
5800d000.usb:hub@1-vdda 1 0mA 0mV 0mV
After:
v3v3 11 10 0 normal 3300mV 0mA 3300mV 3300mV
...
5800d000.usb:hub@1-vdda 1 0mA 0mV 0mV
5800d000.usb:hub@1-vdd 1 0mA 0mV 0mV
...
vdda 0 0 0 unknown 2900mV 0mA 2900mV 2900mV

Changes in v2:
- Overwrite vdda-supply in stm32mp157f-dk2-scmi as pointed by Sashiko
- Link to v1: https://patch.msgid.link/20260821-usb_fixes_vdda-v1-v1-0-0c213062165f@foss.st.com
