From 7cd42e725a0221bb9c0443b15311fe3f5d37ed97 Mon Sep 17 00:00:00 2001
From: Vladimir Barinov <vladimir.barinov@cogentembedded.com>
Date: Wed, 9 Oct 2019 18:34:48 +0300
Subject: [PATCH] arm64: dts: r8a7798-v3hsk-vb-4/8ch: change i2c rate to 400khz
Change i2c rate to 400kHz for bus with cameras.
This speeds up the cameras backchannel transactions.
The restriction of 100khz for cs2300 looks not needed for rev C1 chip.
