Hi all,
This patch series adds initial support for the Renesas RZ/G3L SoC and
RZ/G3L SMARC EVK platform. The RZ/G3L device is a general-purpose
microprocessor with a quad-core CA-55, single core CM-33, Mali-G31
3-D Graphics and other peripherals.
Support for the below list of blocks is added in the SoC DTSI (r9a08g046.dtsi):
- EXT CLK
- 4X CA55
- SCIF
- CPG
- GIC
- ARMv8 Timer
This series also adds SCIF support for the RZ/G3L SMARC EVK board (r9a08g046l68-smarc.dts).
