Subject: [PATCH v3 0/7] Add Renesas RZ/G2UL Type-1 {SoC,SMARC EVK} support
Date: Tue, 15 Mar 2022 14:26:37 +0000 [thread overview]
Message-ID: <20220315142644.17660-1-biju.das.jz@bp.renesas.com> (raw)
Hi All,
RZ/G2UL Family SoC consists of Type-1 and Type-2 SoC's.
Both these SoC's has single Core 1.0GHz CA-55 with similar
peripheral IP's to that of RZ/G2LC and RZ/G2L.
The difference between Type1 and Type2 SoC's are as follows
Function Type1 Type2
SCIF 5ch {0,1,2,3,4} 4ch {0,1,2,3}
Ethernet 2ch {0,1} 1ch {0}
SSI 4ch {0,1,2,3} 3ch {0,1,2}
ADC 2ch {0,1} N/A
DU 1ch Parallel I/F N/A
RZ/G2UL Type-2 is pin compatible with RZ/G2LC, so the number of channels
for each IP matches with RZ/G2LC.
The table below shows the functional differences between RZ/G2LC and
RZ/G2UL Type-2.
Function RZ/G2LC RZ/G2UL Type-2
Cortex-A55 Dual 1.2GHz Single 1.0GHz
DU 1ch MIPI-DSI N/A
GPT 6ch {0,3,4,5,6,7} N/A
Mali-31 1ch N/A
This patch series aims to add support for Renesas RZ/G2UL Type-1 SoC and
basic support for Renesas RZ/G2UL SMARC EVK (based on R9A07G043U11)
- memory
- External input clock
- SCIF
- GbEthernet
It shares the same carrier board with RZ/G2L, but the pin mapping is
different. Place holders are added in device nodes to avoid compilation
errors for the devices which have not been enabled yet on RZ/G2UL SoC.
Also disable the device nodes which is not tested and delete the
corresponding pinctrl definitions.
