[PATCH v3 15/16] arm: dts: ls1028a-rdb: sync device tree with Linux

Vladimir Oltean vladimir.oltean at nxp.com
Mon Jan 3 13:47:36 CET 2022


Allow device trees to be reused between Linux and U-Boot.
The source for these device trees is linux-next as of commit
bd8a9cd624c6 ("arm64: dts: ls1028a-rdb: update copyright"), which was
chosen because some changes needed to be done to the Linux DTs too,
before they could be shared:
https://lore.kernel.org/linux-arm-kernel/20211202141528.2450169-5-vladimir.oltean@nxp.com/T/#m6f63c92e75fa79a01144b2c2c6dc4776e7971395

There are two more commits on the RDB device tree which haven't been
picked up yet, because they have dependencies on the SoC device tree:

dd3d936a1b17 ("arm64: dts: ls1028a: add ftm_alarm1 node to be used as wakeup source")
b2e2d3e02fb6 ("arm64: dts: ls1028a-rdb: enable pwm0")

These will be picked up on the next resync.
