This patchset is the initial patchset for Allwinner DE2 support.
It contains the support of clocks in DE2 and the mixers in DE2.
The SoC used to develop this patchset is V3s, as V3s is the simplest one of the SoCs that have DE2. (Allwinner V3s features only one mixer, although its clock control unit contains support for second mixer's clock; and its only video output is RGB LCD, which is already supported in our TCON driver)
The last patch is only a testing patch, it shouldn't be merged; and for the patch to be really usable, the RFC fix of the TCON driver [1] is needed.
No HDMI, TV encoder or other internal bridges' support is included in this patchset, which makes it currently not usable on H3. (Some WIP code have already been written based on v4 of this patchset by Jernej Skrabec and be, including TVE support (basical but usable) and HDMI support (can display something, but still not so usable because of some problem). )
Thanks to Jean-Francois Moine and Jernej Skrabec for their efforts to discover the internal of DE2!
