I forgot to mention possible conflict for multi_v7_defconfig (with

I just looked through the remaining warnings in 4.15 and noticed that
you had sent this
only for 4.16, not as a bug fix.

Looking closer, it seems incorrect:

According to the comment added to exynos_dt_pmu_match[] in commit
8b283c025443 ("ARM: exynos4/5: convert pmu wakeup to stacked domains"),
the RTC is not able to wake up the system through the PMU on Exynos5410,
unlike Exynos5420. However, when the RTC DT node got added in commit
e1e146b1b062 ("ARM: dts: exynos: Add RTC and I2C to Exynos5410"), it was
a straight copy of the Exynos5420 node, which now causes the warning from dtc,
and now you add the "interrupt-controller" property to the device node, but
the code still doesn't handle it at all.

Can you have another look here?

I received a Odroid XU board, based on Exynos5410, from Markus Reichl
(big thanks! it is second board from fivetechno.de) but I did not
setup testing infrastructure on it yet.

I see you pulled my entire DT branch, including the change around
Exynos5410 PMU's interrupts. I think your analysis and your follow-up
patch are correct which means that RTC on Exynso5410 might be broken
now. It is getting late in RC-cycle so I could send a follow-up pull
with fixed DT including your patch [1].

The other way is to drop my commit entirely. I could prepare a rebased
DT branch for this as well.

Let me know if you have any preferences.

Best regards,
Krzysztof

One question: do you know if anyone is working on support for the newer
Exynos chips, or the Nexell S5P6818 series? It seems odd that none of
the chips from the past three years are supported yet.

For the new Exynos chips - I think Samsung folks are working on them.
Indeed it looks like the pace for new chips has slowed down.

The Nexell series are similar to Exynos but this is different company
so probably they would end up in different sub-arch. Only some IP
blocks are similar to Exynos even though the datasheet has Samsung
marks. I saw patches for U-Boot (I do not remember the author) so
maybe soon something will happen on LKML.

Krzysztof

Ok. When I looked at an old 32-bit 3.4 kernel tree, I could see no similarity
to Exynos, but it seems that there is now an active development tree for
a 64-bit 4.x kernel for the Samsung Artik board series, just no patches.
