From f5bbc93937aca00fa2de458b7ffa2d9beb59649e Mon Sep 17 00:00:00 2001 From: Conor Dooley Date: Tue, 5 Jul 2022 22:52:02 +0100 Subject: [PATCH] dt-bindings: display: convert ilitek,ili9341.txt to dt-schema A dt-schema binding for the Ilitek ili9341 was created as panel/ilitek,ili9341.yaml but the txt binding was ignored in the process. Move the remaining items in the txt binding to the yaml one & delete it. The example in the txt binding has a spi-max-frequency which disagrees with the yaml replacement (and its own documentation) so change that to conform with the binding. There are no users in tree of the Adafruit yx240qv29 to check against.
