Subject: [PATCH v2 3/4] ARM: dts: exynos: add initial data for coupled regulators for Exynos5422/5800

Declare Exynos5422/5800 voltage ranges for opp points for big cpu core and
bus wcore and couple their voltage supllies as vdd_arm and vdd_int should
be in 300mV range.

This one was previously from Marek, now it is from you. Any changes here?

Hmmm, it seems that "From:" tag somehow got lost in v2 compared to v1?

Also the note about adding patch description (which was the only update to
original Marek's patch IIRC) should be added, something like:

...
Signed-off-by: Marek Szyprowski <[email protected]>
[k.konieczny: add missing patch description]
Signed-off-by: Kamil Konieczny <[email protected]>
