[PATCH v2 0/3] ARM: dts: stm32: Fix STM32MP1 ev and dk USB onboard HUB supplies

[Fabrice Gasnier]

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
