[PATCH 0/4] NXP LS1028A-RDB preparation for device tree sync with U-Boot

[Vladimir Oltean]

An effort was started for the NXP LS1028A to share device trees between
Linux and U-Boot, and so far the common SoC dtsi is shared, but
individual boards still aren't. This patch makes some minor changes to
the Linux device tree so the DT for the reference design board can be
successfully shared with U-Boot.

[PATCH 1/4] arm64: dts: ls1028a-rdb: sort nodes alphabetically by label

[Vladimir Oltean]

In preparation for this board's device tree synchronization with U-Boot,
we must find a common node ordering pattern. Alphabetical sounds about
right.

[PATCH 2/4] arm64: dts: ls1028a-rdb: add an alias for the FlexSPI controller

[Vladimir Oltean]

This is used by U-Boot and is required for keeping the device trees in
sync.
