From 4abfe6f04d93e4aac202007486266bd1a904cc43 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 21 Feb 2020 11:55:34 +0900 Subject: [PATCH] dt-bindings: i2c: Convert UniPhier FI2C controller to json-schema Convert the UniPhier FIFO-builtin I2C (a.k.a. FIFO) controller binding to DT schema format. There are two types of I2C controllers used on the UniPhier platform. This is the new one with FIFO support, which is used on the Pro4 SoC or newer.
