From 370f696e44745b321054496fa351dade03fc4bd9 Mon Sep 17 00:00:00 2001 From: Conor Dooley Date: Wed, 8 Feb 2023 17:17:16 +0000 Subject: [PATCH] dt-bindings: serial: snps-dw-apb-uart: add dma & dma-names properties Commit 0c559bc8abfb ("dt-bindings: serial: restrict possible child node names") exposed the Allwinner D1 devicetrees as users of unevaluated properties, with a slew of similar warnings now appearing during dtbs_check: sun20i-d1-nezha.dtb: serial@2500400: Unevaluated properties are not allowed ('dma-names', 'dmas' were unexpected) Document the missing properties.
