This patch series aims to add DMAC support on RZ/G2L SoC's.

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 <dt-bindings/clock/r9a07g044-cpg.h> 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.
