Hello,

This patchset is a next step to add support for all power domains on
Exynos5433 SoCs. This patchset contains patches for Exynos pin control
driver and Exynos LPASS MFD driver, which are needed to make the
platform ready for adding power domains support.

Patches in this patchset have runtime dependency. They are order in such
a way to make the changes bisectable (mfd lpass changes should be applied
after pinctrl patches). Other dependencies mentioned previously in v3 of
this patchset has been finally merged to v4.11-rc1.

Patches have been rebased on top of linux v4.11-rc3.

Best regards
