[PATCH V2 0/7] Add Renesas RZ/G2UL Type-1 {SoC,SMARC EVK} support

[PATCH V2 0/7] Add Renesas RZ/G2UL Type-1 {SoC,SMARC EVK} support

[Biju Das]

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.

[PATCH V2 1/7] dt-bindings: power: renesas,rzg2l-sysc: Document RZ/G2UL SoC

[Biju Das]

Add DT binding documentation for SYSC controller found on RZ/G2UL SoC's.
SYSC controller found on the RZ/G2UL SoC is almost identical to one found
on the RZ/G2L SoC's only difference being that the RZ/G2UL has only CA55
core0 reset vector address configuration register.

[PATCH V2 5/7] clk: renesas: Add support for RZ/G2UL SoC

[Biju Das]

The clock structure for RZ/G2UL is almost identical to RZ/G2L SoC with
fewer IP blocks. The IP blocks such as WDT1, GPT, H264, GPU and POEG are
not present on RZ/G2UL.

This patch adds minimal clock and reset entries required to boot the
system on Renesas RZ/G2UL SMARC EVK and binds it with the RZ/G2L CPG core
driver.

[PATCH V2 6/7] arm64: dts: renesas: Add initial DTSI for RZ/G2UL SoC

[Biju Das]

Add initial DTSI for RZ/G2UL SoC.

Both RZ/G2L and RZ/G2UL uses the same SMARC EVK. Therefore they share
the common dtsi (rz-smarc.dtsi) file. Place holders are added in
device nodes to avoid compilation errors for the devices which have
not been enabled yet on RZ/G2UL SoC.

Signed-off-by: Biju Das <biju.das.jz@bp.renesas.com>

[PATCH V2 7/7] arm64: dts: renesas: Add initial device tree for RZ/G2UL Type-1 SMARC EVK

[Biju Das]

Add basic support for RZ/G2UL SMARC EVK (based on R9A07G043U11):
- memory
- External input clock
- CPG
- DMA
- SCIF

It shares the same carrier board with RZ/G2L, but the pin mapping is
different. Disable the device nodes which are not tested and delete the
corresponding pinctrl definitions.

Likewise (cfr. my comments on 1/7), I think this should use
ARCH_R9A07G043 instead.

Rev. 0.51 of the RZ/G2UL Hardware User's Manual still lists the same
ID as RZ/G2L, so I can't check this :-(

 "renesas,r9a07g043", so it catches both Type-1 and Type-2 SoCs?

OK, I will use ARCH_R9A07G043.

I got confirmation from HW people this is wrong in HW user's manual and will be fixed in the next version

OK, Will change it to renesas,r9a07g043"

Likewise, please drop the trailing (upper/lower case) "u".

Unfortunately I cannot comment on the list of clocks, as I don't have
access to that part of the documentation yet.

I think it would be good to compare the RZ/G2UL and RZ/Five clock
lists, so we know if we can handle them in a common driver, possibly
even sharing binding definitions, or need to differentiate.

Gr{oetje,eeting}s,

when I'm talking to journalists I just say "programmer" or something like that.

OK, I will prepare the patch with 

1) Module Clocks/resets common to RZ/G2UL and RZ/Five
2) Module Clocks/resets specifics to RZ/G2UL

Later when we add RZ/Five, will add Module Clocks/resets specifics to RZ/Five.
Is it ok?

Biju
