Samsung tmu and hdmi regression fixes for v4.0

Browse Source 
- The thermal management unit and HDMI (drm mixer driver) related
 reworks have been merged in v4.0 merge window. So if this DT changes
 are missed for v4.0, we regressions in v4.0 release for exynos
 platforms such as exynos5250, exynos5420, exynos4 SoCs.
 
 - Note since there was a dependency with driver side, this cannot
 be sent to upstream during preivous merge window and now it has been
 resolved.

Merge tag 'samsung-fixes-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung into fixes

Merge "Samsung tmu and hdmi regression fixes for v4.0" from Kukjin Kim:

- The thermal management unit and HDMI (drm mixer driver) related
reworks have been merged in v4.0 merge window. So if this DT changes
are missed for v4.0, we regressions in v4.0 release for exynos
platforms such as exynos5250, exynos5420, exynos4 SoCs.

- Note since there was a dependency with driver side, this cannot
be sent to upstream during preivous merge window and now it has been
resolved.

Optional properties:
- power-domains : A phandle and PM domain specifier as defined by bindings of
the power controller specified by phandle.
Some power domains might be powered from another power domain (or have
other hardware specific dependencies). For representing such dependency
a standard PM domain consumer binding is used. When provided, all domains
created by the given provider should be subdomains of the domain
specified by this binding. More details about power domain specifier are
available in the next section.

The node above defines a power controller that is a PM domain provider and
expects one cell as its phandle argument.
Example 2:

reg = <0x12340000 0x1000>;

The nodes above define two power controllers: 'parent' and 'child'.
Domains created by the 'child' power controller are subdomains of '0' power
domain provided by the 'parent' power controller.
