Subject: [PATCH v4 0/2] dmaengine: Add UniPhier XDMAC driver

Add support for UniPhier external DMA controller (XDMAC), that is
implemented in Pro4, Pro5, PXs2, LD11, LD20 and PXs3 SoCs.

Changes since v3:
- dt-bindings: Fix typo

Changes since v2:
- dt-bindings: Fix SPDX and some properties
- Fix iteration count calculation for memcpy
- Replace zero-length array with flexible-array member in struct
  uniphier_xdmac_device.

Changes since v1:
- dt-bindings: Rewrite with DT schema.
- Change return type of uniphier_xdmac_chan_init() to void,
  and remove error return in probe.

Kunihiko Hayashi (2):
  dt-bindings: dmaengine: Add UniPhier external DMA controller bindings
  dmaengine: uniphier-xdmac: Add UniPhier external DMA controller driver
