This is the first batch of fixes and updates for the Meson8/8b/8m2 clock controller driver.
The first patch fixes the video clock hierarchy. Special thanks to Neil for providing a lot of details about the video clock tree!
The second and third came up while testing video output on my EC-100 (Endless Mini). This board is special because u-boot does not enable the video outputs like most other u-boot versions do. However, this is very useful for development because it shows (the hard way ;)) where the existing code is buggy.
The last patch is a small improvement for the VPU clock so we utilize the glitch-free mux (on SoCs which support it) and avoid problems by changing the "live" clock tree at runtime (with the mali clock this resulted in system hangs/freezes).
In my opinion all of these patches - including the fixes - can go to "next" because the relevant clock trees are still read-only.
