From: Matthew Gerlach <[email protected]>
This patch set adds a device tree for the Hard Processor System (HPS)
on an Agilex based Intel n6000 board.
Patch 1 defines the device tree binding for the HPS Copy Engine IP
used to copy a bootable image from host memory to HPS DDR.
Patch 2 defines the binding for the Intel n6000 board itself.
Patch 3 adds the device tree for the n6000 board.
Changelog v2 -> v3:
- remove unused label
- move from misc to soc
- remove 0x from #address-cells/#size-cells values
- change hps_cp_eng@0 to dma-controller@0
- remote inaccurate 'items:' tag
- added Acked-by
- add unit number to memory node
- remove spi node with unaccepted compatible value
Changelog v1 -> v2:
- add dt binding for copy enging
- add dt binding for n6000 board
- fix copy engine node name
- fix compatible field for copy engine
- remove redundant status field
- add compatibility field for the board
- fix SPDX
- fix how osc1 clock frequency is set

+description: |
+ The Intel Hard Processor System (HPS) Copy Engine is an IP block used to copy
+ a bootable image from host memory to HPS DDR. Additionally, there is a
+ register the HPS can use to indicate the state of booting the copied image as
+ well as a keep-a-live indication to the host.
