Sat Jan 25 13:22:47 CET 2020
This patch adds .dtsi file(sync with Linux 5.5) and required binding
for S700 SoC that is a 64-bit Quad-core ARM Cortex-A53 cores.
Signed-off-by: Amit Singh Tomar <amittomer25 at gmail.com>
---
Changes since v2:
* Synced DTS bindings with Linux 5.5.
Changes since v1:
* Moved the u-boot specific changes to s700-u-boot.dtsi, now
s700.dtsi is in complete sync with Linux 4.20.
