The ldb_di[0/1]_ipu_div clock dividers in the CSCMR2 register of i.MX53, i.MX6Q and i.MX6DL SoCs can be configured to a 1/3.5 drivider or a 1/7 divider. The common clock framework cannot deal with the two dividers directly even with the divider table which only supports integral dividers. So, the idea is to take the 1/3.5 and 1/7 dividers as separate fixed factor dividers and introduce a new multiplexer clock to be derived from the them. Then, the ldb display clock trees can be setup correctly. This series contains the necessary clock driver changes, dts code changes and imx-drm/ldb driver changes to fullfill the task.
