Hi All,
RZ/G2L and RZ/G2LC SoC's are similar and they share the same DEVID.
RZ/G2LC has fewer peripherals compared to RZ/G2L.
SSI (3 channels vs 4 channels)
GbEthernet (1 channel vs 2 channels)
SCIFA (4 channels vs 5 channels)
ADC is only supported in RZ/G2L.
This patch series aims to add support for Renesas RZ/G2LC SoC and
basic support for Renesas RZ/G2L SMARC EVK (based on R9A07G044C2)
- memory
- External input clock
- SCIF
- GbEthernet
- Audio Clock
It shares the same carrier board with RZ/G2L, but the pin mapping is
different. Disable the device nodes which is not tested and
delete the corresponding pinctrl definitions.
Note:-
On the H/W manual Number of Supported SSI channels as 2 and
SCIFA as 3. I got clarification from HW team that it is 3 and 4.
