Hi,
I have tested this patch on my Odroid U3 and U3+ using 4.3.0-rc6 from
Tobias' repo at https://github.com/tobiasjakobi/linux-odroid/tree/odroid-4.3.y
and his debug config:
https://raw.githubusercontent.com/tobiasjakobi/odroid-environment/master/sourcecode/system/vanilla-4.3-debug.conf
halt -p works (power goes down to 0W)
reboot does not work, stuck at 0.5W, right after
"systemd-shutdown[1]: rebooting".
reboot did work with 4.3.0-rc3 from above repo (without Alim's patch).
Thanks,

It freezes when going for reboot.
Have to power off/on to boot again.
Btw I use an mmc, not an sd-card.
No other HW connected, just LAN-cable.
Bootloader is u-boot v2015.10.

Hi Alim,
I have installed your patch set above with git am on top of
4.3.0-rc6-00108-gce1fad2 torvalds/linux of today
with make exynos_defconfig on Odroid U3.
"halt -p" worked (power 0.0W).
"reboot" got stuck at 0.5W.
Without your patch set reboot worked.

This does not look right.
You put this Tested-by since beginning of this patchset (v1) but first
it was LDO10. Then you proposed LDO18 and now you use LDO7 from my
suggestion. Which of this was tested by Markus because I cannot find his
emails with it on LKML?
Markus Reichl tested the earlier version with LDO10.
This is right.
Commit logs got carry forward by mistake.

Changes rebase on
git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung branch
for-next
Changes from v5: Use LDO7 regulator instead of LD010.
The output of LDO18 goes to VDD_EMMC_1V8. This is not regulator for TMU.
I think the schematics are missing some of details but it can be deducted
that:
1. TEMP SE is supplied by VDD18_TS power domain. It consists of 5
pairs of pins (XTSTEST_OUT[0-4], XTSEXT_RES[0-4]).
2. The VDD18_TS01, VDD18_TS23 and VDD18_TS4 are wired to the LDO7 of
S2MPS11 PMIC.
3. I confirmed with the Exynos5422 datasheet that these
VDD18_TS{01,23,4} supply the XTSTEST pins (OUT and RES).
So the LDO7 it is... but before using it there is a caveat. The LDO7
is also connected to VDD of MIPI, HDMI and few more. So when you use
this regulator in TMU it may be turned off by TMU driver (e.g. during
unbind). In such case these other blocks also should be tested and
checked whether they take this regulator and enable it.

is now a mandatory property.
This patch fixes probe failure of s3c-rtc on Odroid-XU3 boards.
It is based on v4.0-rc2.

When you re-spin your patches with small changes, you should keep all
the {Reviewed,Tested,Acked}-by tags collected on previous versions so
the maintainer picking the patches knows who already reviewed the code.
Best regards,
Javier
Ok, will copy it in next time.

+Binding for Samsung S2MPS11 32k clock generator block
+
+This is a part of device tree bindings of S2MPS11 multi-function device.
+More information can be found in bindings/mfd/s2mps11.txt file.
+
+The S2MPS11 contains three 32.768khz clock outputs that can be controlled
+(gated/ungated) over I2C.
+
+Following properties should be present in main device node of the MFD chip.
+
+Required properties:
+- #clock-cells: From common clock binding; shall be set to 1.
+
+Optional properties:
+- clock-output-names: From common clock binding.
+
+Each clock is assigned an identifier and client nodes can use this identifier
+to specify the clock which they consume. Following indices are allowed:
+ - 0: 32khz_ap clock,
+ - 1: 32khz_cp clock.
+ - 2: 32khz_bt clock
+
+Clocks are defined as preprocessor macros in
dt-bindings/clock/samsung,s2mps11.h
+header and can be used in device tree sources.
+
+Example: Node of the MFD chip
+
+ s2mps11: s2mps11@66 {
+ compatible = samsung,s2mps11;
+ interrupt-parent = wakeup_eint;
+ interrupts = 26 0;
+ reg = 0x66;
+ #clock-cells = 1;
+
+ /* ... */
+ };
+
+Example: Clock consumer node
+
+ foo@0 {
+ compatible = bar,foo;
+ /* ... */
+ clock-names = my-clock;
+ clocks = s2mps11 S2MPS11_CLK_32K_AP;
+ };
+
+Presently (19.3.2015) the above said is not correct yet.
+Until s2mps11 mfd driver is updated you still need to specify like that:
+
+ s2mps11: s2mps11@66 {
+ compatible = samsung,s2mps11-pmic;
+ reg = 0x66;
+ s2mps11_osc: clocks {
+ #clock-cells = 1;
+ clock-output-names = s2mps11_ap,
+ s2mps11_cp, s2mps11_bt;
+};
+ /* ... */
+ }
+
+ foo@0 {
+ compatible = bar,foo;
+ /* ... */
+ clock-names = my-clock;
+ clocks = s2mps11_osc S2MPS11_CLK_AP;
+
+};

[PATCH V3 2/2] ARM: dts: exynos5422-odroidxu3: add 'rtc_src' clock to rtc node
The Exynos5422 SoC has a s3c6410 RTC where the source clock
is now a mandatory property.
This patch fixes probe failure of s3c-rtc on Odroid-XU3 boards.
It is based in v4.0-rc2.
