From: Alexander Graf Date: Wed, 4 Oct 2017 12:39:16 +0000 (+0200) Subject: fdt: update bcm283x device tree sources to Linux 4.14 state X-Git-Tag: v2017.11-rc2~32 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=409f05f259ee5cb3e13b52279ce2365a6f8b8a8b;p=u-boot fdt: update bcm283x device tree sources to Linux 4.14 state Upstream Linux has received a few device tree updates to the RPi which we should propagate into the builtin U-Boot one as well to gain hardware support. This patch bumps the dts files to their 4.14 Linux counterparts with the exception of sdhost on 32bit RPi versions. There we stay with iproc as the sdhost driver is missing in U-Boot.
