Add device-tree support for the following SoMs:
- Mercury SA1 (cyclone5)
- Mercury+ SA2 (cyclone5)
- Mercury+ AA1 (arria10)
Further add device-tree support for the corresponding carrier boards:
- Mercury+ PE1
- Mercury+ PE3
- Mercury+ ST1
Finally, provide generic support for combinations of the above with
one of the boot-modes
- SD
- eMMC
- QSPI
Almost all of the above can be freely combined. Combinations are
covered by the provided .dts files. This makes an already existing
.dts file obsolete. Further minor fixes of the dtbs_checks are
added separtely.
The current approach shall be partly useful also for corresponding
bootloader integration using dts/upstream. That's also one of the
reasons for the .dtsi split.
Note: Pls, take this as a draft, in particular I have the following
open questions and would appreciate to get some short statement:
1.) Documentation/devicetree/bindings:
Executing the following find...
$ find ./Documentation/devicetree/bindings -name socfpga-\*.txt
...shows 4 text files describing "altr," bindings. I sketch-implemented
the clock binding and could reduce some of my dtbs_check warnings. So, my
questions is, if this is the right way? Shall I try to write .yaml files
for all 4 of them, too? Related to that, who will be maintainer?
2.) Some bindings, e.g. the Silabs clock generator seem to have no
driver, thus show up as warning:
compatible = "silabs,si5338";
IMHO it is most likely rather to be probed/loaded in the SPL of the
bootloader. Is it problematic to keep those declarations (showing up as
warning in dtbs_check) or how to deal with them?
3.) Please, give me some feedback if the DT and binding adjustments are
going into total wrong direction, or where I may do better. If it is ok,
and acceptable, or what is still missing. I tried to split them, to
allow for better single integration / discussion let me know if this is
ok, too.
---
v1 -> v2:
- split bindings and DT adjustments/additions
- add several fixes to the socfpga.dtsi and socfpga_arria10.dtsi where
bindings did not match
- extend existing bindings by properties and nods from arria10 setup
- implement the clock binding altr,socfpga-a10.yaml based on existing
text file, rudimentary datasheet study and requirements of the
particular DT setup
