Hi all,
This patch series adds initial support for the Renesas RZ/G3E SoC and
RZ/G3E SMARC EVK platform. The RZ/G3E device is a general-purpose
microprocessor with a quad-core CA-55, single core CM-33, Ethos-U55 NPU
, Mali-G52 3-D Graphics and other peripherals.
Support for below list of blocks added on SoC DTSI (r9a09g047.dtsi):
- EXT CLKs
- 4X CA55
- SCIF
- CPG
- GIC
- ARMv8 Timer
This adds also support for the RZ/G3E SMARC EVK board
(r9a09g047e57-smarc.dts) and enable the following peripheral:
- SCIF
Note:
This patch series gives a boot console with serial driver support.
Later there is a plan to add support for SoC Identification using
SYSC driver and pin controller support were also added.
