[PATCH v2 0/4] ARM/arm64: exynos: Fix missing missing reg warning for syscon restart nodes

[Krzysztof Kozlowski]

Hi,

Changes since v1:
1. New patch (1/4) calling devm_of_platform_populate() in PMU driver,
   following Rob's advice.
2. The DTS patches moving reboot/poweroff nodes (3/4 and 4/4) now depend
   on this.

Best regards,
Krzysztof

[PATCH v2 1/4] soc: samsung: pmu: Populate children syscon nodes

[Krzysztof Kozlowski]

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

This also requires providing compatibles for Exynos5410 and Exynos7 so
the PMU device and its children will be instantiated for them as well.
Just like Exynos5433, these chipsets are not yet supported by the PMU
driver.

[PATCH v2 2/4] ARM: dts: exynos: Remove duplicated inclusion of syscon restart nodes on Exynos5410

[Krzysztof Kozlowski]

The exynos-syscon-restart.dtsi is already included by exynos5.dtsi
(through exynos54xx.dtsi).

[PATCH v2 3/4] ARM: dts: exynos: Fix missing missing reg warning for syscon restart nodes

[Krzysztof Kozlowski]

Fix DTC warnings like:

    arch/arm/boot/dts/exynos4412-trats2.dtb: Warning (simple_bus_reg):
        Node /soc/syscon-poweroff missing or empty reg/ranges property
    arch/arm/boot/dts/exynos4412-trats2.dtb: Warning (simple_bus_reg):
        Node /soc/syscon-reboot missing or empty reg/ranges property

by moving the syscon poweroff and restart nodes into the PMU (Power
Management Unit) node.  The PMU node is the actual block responsible for
power management, including typical Exynos on/off/restart procedures.
Therefore the syscon poweroff and restart nodes logically belong to it.

Doesn't seem to work on mine:
Exynos4412 (odroid u2)

Rebooting worked correctly with 3.8 + gazillion non-mainlined patches (as
shipped with providen images), never did with mainline.

Tested on current mid-of-the-merge-window, plus these four patches.


It's possible that I'm doing something wrong; might need an updated u-boot,
etc.  Log of a boot-till-reboot+hang session attached.

Reboot on Odroid X2/U2/U3 doesn't work now. It is broken by devfreq since
a few kernel releases. Please disable devfreq in your .config and reboot
should also work. That's why I didn't put Odroid U3 on the above list.

Thanks for testing. I applied 1/4 and 2/4. The remaining DTS patches
depend on 1/4 so they will wait till next release.
