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.
