It is based on the work done by Chris Brandt for RZ/A DMA driver. This patch series is based on [1] [1] https://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers.git/log/?h=topic/rzg2l-update-clock-defs-v4 Note:- This patch has dependency on #include file which will be in next 5.14-rc1 release. v2->v3: * Described clocks and resets in binding file as per Rob's feedback. v1->v2 * Started using virtual DMAC * Added Geert's Rb tag for binding patch.
