The Ingenic JZ4760 and JZ4770 both have an extra DMA core named BDMA dedicated to the NAND and BCH controller, but which can also do memory-to-memory transfers. The JZ4760 additionally has a DMA core named MDMA dedicated to memory-to-memory transfers. The programming manual for the JZ4770 does have a bit for a MDMA clock, but does not seem to have the hardware wired in. Add macros for the MDMA and BDMA clocks to the dt-bindings include files, so that they can be used within Device Tree files.
