From 4d8d2177625c26488e29f2ccd5194df29466f2ff Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ricardo=20Ca=C3=B1uelo?= Date: Mon, 13 Apr 2020 12:30:47 +0200 Subject: [PATCH] dt-bindings: nvmem: Convert rockchip-efuse bindings to yaml MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Convert the existing rockchip-efuse binding to json-schema. No changes were done to the binding except for small changes in the documentation strings. This deletes the rockchip-efuse.txt binding and replaces it with rockchip-efuse.yaml.
