[PATCH 2/2] ARM: dts: stm32: Synchronize DHCOM DTs with Linux 5.15.12

Marek Vasut marex at denx.de
Thu Dec 30 23:46:47 CET 2021


Synchronize DH DHCOM DTs with Linux commit 25960cafa06e ("Linux 5.15.12").
There is no functional change to the resulting DTs. The eeprom0 alias and
PHY reset GPIO are now reinstated in SoM u-boot dtsi.
