These bridges should be operational during power domain switching, ie associated clocks cannot be gated. This patchset adds binding to provide such clocks per power domain and adds code which enables them during domain on/off operation. This patchset fixes power domain issues with disp1 domain and HDMI (some of them) on Odroid XU3: - disp1 power domain can be turned off, - no more "imprecise external abort" faults. The patchset is based on '[PATCH v5 0/9] Enable HDMI support on Exynos platforms' [1]. It was successfully tested on OdroidXU3.
