This IP block has at least one additional input called "sys_pll_div16".
My understanding is that the "sys_pll_div16" clock is generated by the
CPU clock controller. Support for the CPU clock controller
(dt-bindings and a driver) will be added at a later time by Dmitry.
How can we manage incrementally implementing the clock controllers?

How to manage this in the .dts patches then (for example: does this
mean that Dmitry can only add the clock controller to the .dts when
all clock controller bindings have been implemented - or is there
another way)?


Best regards,
Martin
