Re: [PATCH v5 07/11] arm: actions: add S700 SoC device tree

On Wed, 11 Mar 2020 23:34:17 +0530 Amit Singh Tomar amittomer25@gmail.com wrote:

Hi,

This patch adds .dtsi file(sync with Linux 5.5-rc6 with hash "b3a987b0264d") and required binding for S700 SoC that is a 64-bit Quad-core ARM Cortex-A53 cores.

It also provisions dts file to be built based on selected platform(CONFIG_MACH_S900/S700).

Cheers, Andre

Changes since v4:

• Move it to 07/11 from 05/11.

Changes since v3: * Updated commit message to the Linux tag to which the dtsi file is synced. 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.
