Samsung tmu and hdmi regression fixes for v4.0
- 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. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJU9LGEAAoJEA0Cl+kVi2xqXHYP/jyUQoCEEtgBrm9Rui0JgeJ5 AxknhqAQQNNSL5npsGGkrmYNsZraIwn5rfALCbXAt0xfq+pACiqYLna81J2j33dF fk5t2MzmoHFKrDxeR7uQOgGd6QU9q4nRUL0Cttp7G38BBCJkH/cj6nu8RxVpl2b3 walBlRmgt8AKzFNCeOaNxpp0dmOj1RSU8xLwR4bvo3qWPSNI9LrqkCfSz1/gZLOQ J6e9U6+GmOPiui6aEpI+9CQ78amrMUE0QwgI5YJwVNWT0Vx0kG8SWV0DRGPz8UJv aFrizdSdqHZWVaMez+yv7sM5ga+KHqseWX29lVgcJHXj3tlMpsP0RH3Vvq2jDkfG AEbcsTbm6Jd9kbq9/Edr/TDIu97SLmQhLM7wm1EBhi70CuglPeLWydB23sXL3wCc 5V1sPIEiLx0epcfP6JIHHExKS2amBR7RHbn5E+mWjs9ChKCDNyG/6cu7eWzFGrFm LW4MHwU4dW9WHOzMBUDPnMrDhpJYe+9XLBgzeD67xda2YE80BAb2Ro/LO/pwEv5y spuFqDlXnahOs4wP68f+TDHyhPg81QbkC+35w+mNXFYEgUQbROm4PgHEK4jRbB5K zAZHIReEwYqxne5Suv6uSAUiiBmaa3aujnj56bhwHns6KDYnVmCdbw6h0CymAtSA Inie5Ipbq5XAtatLVWA+ =gbWq -----END PGP SIGNATURE----- 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.

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.
