[PATCH v11 08/15] arm64: dts: Add AMD Pensando Elba SoC support

Brad Larson
2023-03-12T00:47:03Z

Add AMD Pensando common and Elba SoC specific device nodes

Signed-off-by: Brad Larson <blarson@amd.com>
---

v11 changes:
- Delete reset-names
- Fix spi0 compatible to be specific 'amd,pensando-elba-ctrl'

v9 changes:
- Single node for spi0 system-controller and squash
the reset-controller child into parent
