v3 cover soc: loongson: Fix some issues about loongson2_pm

Hi all:

Since commit 67694c076bd7 ("soc: loongson2_pm: add power management support"), the Loongson-2K PM driver was added, some issues have been found and this patchset is planned to fix these issues.

Specific:
Patch 1: Compilation error found by Randy;
Patch 2/3: Rewriting the ls2k-pmc compatible attribute with fallback compatible;
Patch 4/5: Add Loongson-2K SoC reboot/shutdown support as part of power management.

Thanks.

-----
V3:
- Changes "loongson_pm2" to "loongson2_pm" in all subject lines. Sorry, it was a clerical error.
patch 1:
- Add Fixes tag;
- Update commit message.
patch 2:
- Add Fixes and Acked-by tag.
patch 3:
- Add Fixes tag;
patch 4:
- Add Reviewed-by tag.

Link to V2:
https://lore.kernel.org/all/[email protected]/

V2:
patch 1:
- Change "depends on INPUT" to "depends on INPUT=y", because the compilation error still exists when "INPUT=m".
patch 2:
- Use ls2k0500 as the fallback compatible;
- Add ls2k2000 compatible.
patch 3:
- Drop ls2k1000 compatible, for ls2k0500 is used as the fallback compatible.
patch 4:
- Drop label;
- Drop regmap property in syscon-reboot, for it's deprecated;
- Add missing space.

PATCH v3 2/5 dt-bindings: soc: loongson,ls2k-pmc: Use fallbacks for ls2k-pmc compatible

The Loongson-2K series chips (ls2k0500/ls2k1000/ls2k2000) share the same PM system controller, using ls2k0500 compatible as fallback for the others.

PATCH v3 1/5 soc: loongson: loongson2_pm: Add dependency for INPUT

In reply to Binbin Zhou

Since commit 67694c076bd7 ("soc: loongson2_pm: add power management support"), the Loongson-2K PM driver was added, but it didn't update the Kconfig entry for the INPUT dependency, leading to build errors:

/opt/crosstool/gcc-13.2.0-nolibc/loongarch64-linux/bin/loongarch64-linux-ld:

Also, since this driver can only be built-in, it fails to link when the INPUT is in a loadable module, so we should update the Kconfig entry to depend on INPUT=y.

PATCH v3 3/5 soc: loongson: loongson2_pm: Drop useless of_device_id compatible

In reply to Binbin Zhou

Now, "loongson,ls2k0500-pmc" is used as fallback compatible, so the ls2k1000 compatible in the driver can be dropped directly.

PATCH v3 4/5 dt-bindings: soc: loongson,ls2k-pmc: Allow syscon-reboot/syscon-poweroff as child

In reply to Binbin Zhou

The reboot and poweroff features are actually part of the Power Management Unit system controller, thus allow them as its children, instead of specifying as separate device nodes with syscon phandle.

Without it, the reboot/poweroff feature becomes unavailable.

PATCH v3 5/5 soc: loongson: loongson2_pm: Populate children syscon nodes

In reply to Binbin Zhou

The syscon poweroff and reboot nodes logically belong to the Power Management Unit so populate possible children.

Without it, the reboot/poweroff feature becomes unavailable.

Also, since this driver can only be built-in, it fails to link when the INPUT is in a loadable module, so we should update the Kconfig entry to depend on INPUT=y.

Sorry, I have been traveling and not pushed out the tree yet.

Can you confirm that the input dependency is required for 6.6 and the other series can wait until 6.7? When you send patches to [email protected], please always mention which tree you intend them for. I might disagree, but it's better than having to guess.

Hi Arnd:

Thanks for your reply.

As we know, this driver was just merged in during the v6.6 window, and no release will use it until now:

commit 67694c076bd7 soc: loongson2_pm: add power management support commit 6054a676e969 soc: dt-bindings: add loongson-2 pm

Now, since the Loongson-2K series SoCs are indifferent at the driver level, we used fallback compatible and added syscon-reboot/syscon-poweroff subnodes for power on/off functionality. These somewhat break the original devicetree rules.
So, I think these patches need to be merged in before the v6.6 release to avoid unnecessary compatibility issues.
Of course, I added the "Fixes:" tag in the corresponding patch.

Thanks.
