[PATCH v3 11/11] arm64: dts: Add Pensando Elba SoC support
Brad Larson

Sun Oct 24 18:51:56 PDT 2021
Add Pensando common and Elba SoC specific device nodes
Signed-off-by: Brad Larson <brad at pensando.io>
---
Changelog:
- Node names changed to DT generic names
- Changed from using 'spi@' which is reserved
- The elba-flash-parts.dtsi is kept separate as
it is included in multiple dts files.
- SPDX license tags at the top of each file
- The compatible = "pensando,elba" and 'model' are
now together in the board file.
- UIO nodes removed
- Ordered nodes by increasing unit address
- Removed an unreferenced container node.
- Dropped deprecated 'device_type' for uart0 node.
