[PATCH 0/4] ARM: stm32: USBPHYC updates on stm32mp15

From: Amelie Delaunay <amelie.delaunay@foss.st.com>
Date: 2021-01-14 12:14:20 

This series updates usbphyc parent and child nodes to follow latest DT
bindings.

Amelie Delaunay (4):
  ARM: dts: stm32: add usbphyc vdda1v1 and vdda1v8 supplies on
    stm32mp151
  ARM: dts: stm32: remove usbphyc ports vdda1v1-vdda1v8 on
    stm32mp157c-ed1
  ARM: dts: stm32: remove usbphyc ports vdda1v1-vdda1v8 on
    stm32mp15xx-dkx
  ARM: dts: stm32: add #clock-cells property to usbphyc node on
    stm32mp151

[PATCH 3/4] ARM: dts: stm32: remove usbphyc ports vdda1v1-vdda1v8 on stm32mp15xx-dkx

From: Amelie Delaunay <amelie.delaunay@foss.st.com>
Date: 2021-01-14 12:14:21 

vdda1v1 and vdda1v8 supplies are required by USB PLL, not by the PHYs.
Remove them from usbphyc child phy nodes now that they are managed in
usbphyc parent node at SoC level.

[PATCH 4/4] ARM: dts: stm32: add #clock-cells property to usbphyc node on stm32mp151

From: Amelie Delaunay <amelie.delaunay@foss.st.com>
Date: 2021-01-14 12:14:21 

usbphyc is a 48Mhz clock provider: the clock can be used as clock source
for USB OTG. Add #clock-cells property to usbphyc node to reflect this
capability.

[PATCH 2/4] ARM: dts: stm32: remove usbphyc ports vdda1v1-vdda1v8 on stm32mp157c-ed1

From: Amelie Delaunay <amelie.delaunay@foss.st.com>

vdda1v1 and vdda1v8 supplies are required by USB PLL, not by the PHYs.
Remove them from usbphyc child phy nodes now that they are managed in
usbphyc parent node at SoC level.
