Hi all:
Some liointc-related DTBS_CHECK warnings were found when trying to
introduce the Loongson-2K DTS{I} for LoongArch.
This patch series attempts to fix those warnings, as well as fixing
non-standard property naming.
Of course, these fixes also apply to MIPS Loongson-2K1000.
Thanks.

V5:
- Add Reviewed-by tag;
patch(1/5):

deprecated.

V4:
- Add Acked-by tag;
patch(2/5):
- Just add 'maxitem 2' instead of duplicating the list;
patch(3/5):
- Rewite commit message for 'interrupt-names'.
Link to V3:
https://lore.kernel.org/all/[email protected]/
V3:
patch(1/5):
- new patch, 'loongson,parent_int_map' renamed to 'loongson,parent-int-map';
patch(2/5)(3/5):
- Separate the change points into separate patches;
patch(4/5):
- new patch, make sure both parent map forms can be parsed;
patch(5/5):
- new patch, fix 'loongson,parent_int_map' references in mips loongson
dts{i}.
Link to V2:
https://lore.kernel.org/all/[email protected]/
V2:
1. Update commit message;
2. "interruprt-names" should be "required", the driver gets the parent
interrupts through it;
3. Add more descriptions to explain the rationale for multiple nodes;
4. Rewrite if-else statements.

As we know, the Loongson-2K0500 is a single-core CPU, and the
core1-related register (isr1) does not exist. So "reg" and "reg-names"
should be set to "minItems 2"(main nad isr0).
This fixes dtbs_check warning:

The Loongson-2K0500/2K1000 CPUs have 64 interrupt sources as inputs, and
a route-mapped node handles up to 32 interrupt sources, so two liointc
nodes are defined in dts{i}.
Of course, we have to make sure that the routing outputs ("intx") of the
two nodes do not conflict, i.e. "int0" can only be used as a routing
output for one of them. Therefore, "interrupt-names" should be defined
as "pattern".
In addition, since "interrupt-names" and "interrupts" are one-to-one
correspondence, we pass it to get the corresponding interrupt number in
the driver. Setting it to "required" does not break ABI, because it
is already logically represented as "required".
This fixes dtbs_check warning:

Not what I said to do. Now you just break the ABI instead of maintaining
both names.

Hi Rob:
Thanks for your reply, and I am very sorry that I may have missed your
previous thought, but at the same time I'm confused about how to
handle the 'parent_int_map' attribute.
During the V2 patchset, krzysztof noticed the non-standard naming of
this property and suggested that we rename 'parent_int_map' in the
binding and label it as "deprecated". But you don't think it's worth
doing that.
My understanding is that it doesn't make sense to keep
'parent_int_map' for the new binding, so I'm just going to rename the
property in this version.
It's true that this will result in an ABI break, but at the same time
corresponding changes have been made to the driver as well as in the
existing DTS{i}:
Patch 4: Handles attribute names in both naming styles;
Patch 5: Replace all 'parent_int_map' in the MIPS DTS{i}.
Do you think this is a suitable way to handle this? Or just keep the "_" naming?
Thanks.

Please keep changelogs in neutral or imperative tone:
For backwards compatibility it is required to parse the original
string too.
Makes it entirely clear what this is about without 'we'. See also:

Hi Thomas:
Thanks for the detailed review.
Rob suggested in the V5 patchset to remove the
'loongson,parent-int-map' renaming operation as an ABI breakage[1]. I
had tried to explain that the driver would be compatible with the
parsing of both naming styles[2], but unfortunately did not get a
response from Rob.
As a result, I removed the renaming-related patches in the V6
patchset, including this one[3].
However, how the 'loongson,parent-int-map' renaming operation is
finally going to be handled needs to be decided together, and if it
remains needed, I will fix the above issue and submit it as part of
the V7 patchset.
