This series add a clock driver infrastructure for Rockchip SoCs in general and clock-definitions for the RK3188 in particular. Due to the lack of any usable documentation of the RK3188 clocks, the clock tree is based on my own doc [0] collected by analyzing the clock_data code in current Rockchip kernels. As a result the gathered data may contain errors. So to prevent API issues with the clock-ids, the exported ones are currently limited to well understood or really measured clocks. The previous attempt to define parts separately in the devicetree did not really fit with the clock structure, which became apparent with more knowledge about the clock tree and this new driver framework, heavily inspired by the Samsung clock driver, fits very well for clock controllers in Rockchip SoCs. The whole structure should support Rockchip SoCs at least down to the RK28xx (ARM9) which all share a very similar setup of their clock controllers in PLL, divider and gate handling as well as the included softreset parts.
