This patch adds .dtsi file(sync with Linux 4.20) and required binding for S700 SoC that is a 64-bit Quad-core ARM Cortex-A53 cores.
Signed-off-by: Amit Singh Tomar amittomer25@gmail.com --- 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. --- arch/arm/dts/s700.dtsi | 190 +++++++++++++++++++++++++++ include/dt-bindings/clock/actions,s700-cmu.h | 118 +++++++++++++++++ 2 files changed, 308 insertions(+) create mode 100644 arch/arm/dts/s700.dtsi create mode 100644 include/dt-bindings/clock/actions,s700-cmu.h
