[PATCH v2] ARM: dts: dra7: Fix duplicate USB4 device node
From: Gowtham Tammana
Date: Wed May 26 2021 - 13:21:05 EST
With [1] USB4 device node got defined in dra74x.dtsi file. However,
there was a prior defintion of the same in [2] which didn't get removed
causing boot failures. USB4 node is present only in DRA74x variants so
keeping the entry in dra74x.dtsi and removing it from the top level
interconnect hierarchy dra7-l4.dtsi file.
Since USB4 is only included in DRA74x variants, remove its reference
for AM5718, DRA71x and DR72x boards.
[1]: commit 549fce068a311 ("ARM: dts: dra7: Add l4 interconnect
hierarchy and ti-sysc data")
[2]: commit c7b72abca61ec ("ARM: OMAP2+: Drop legacy platform data for
dra7 dwc3")
Fixes: c7b72abca61ec ("ARM: OMAP2+: Drop legacy platform data for dra7 dwc3")

v2:
- changed reference to commit sha instead of line numbers
- added Fixes: tag
- moved the definition to dra74.dtsi as per Suman and Tony review comments
