PATCH v3 2/4 ARM: dts: rockchip: Add support for RV1103B

From: Fabio Estevam <[email protected]>

Add the initial RV1103B devicetree.

Based on the 5.10 Rockchip vendor kernel.

Signed-off-by Fabio Estevam <[email protected]>

The <dt-bindings/clock/rockchip,rv1103b-cru.h> header comes from another series:

https://lore.kernel.org/linux-devicetree/[email protected]/

Maybe Heiko could apply the clock series as well?

Changes since v1:
- Pass /omit-if-no-ref/
- Removed redundant _pins suffix.
- Dd not merge all GRF region.
- Removed unnecessary clock rate from the UART nodes.
- Removed "normal" and "idle" pinctrl entries and used "default" instead.
- Added missing default pinctrl entries for emmc, sd and fspi.
- Removed gpio-ranges.

Re: [PATCH v3 2/4] ARM: dts: rockchip: Add support for RV1103B

Hi Fabio,

Quoted 40 lines · Fabio Estevam

From: Fabio Estevam <[email protected]>
Add the initial RV1103B devicetree.
Based on the 5.10 Rockchip vendor kernel.
Signed-off-by Fabio Estevam <[email protected]>
---
The <dt-bindings/clock/rockchip,rv1103b-cru.h> header comes from another series:
https://lore.kernel.org/linux-devicetree/[email protected]/
Maybe Heiko could apply the clock series as well?
Changes since v1:
- Pass /omit-if-no-ref/
- Removed redundant _pins suffix.
- Dd not merge all GRF region.
- Removed unnecessary clock rate from the UART nodes.
- Removed "normal" and "idle" pinctrl entries and used "default" instead.
- Added missing default pinctrl entries for emmc, sd and fspi.
- Removed gpio-ranges.

PATCH v3 4/4 ARM: dts: rockchip: Add Onion Omega4 Evaluation Board

In reply to Fabio Estevam

From: Fabio Estevam <[email protected]>

The Onion Omega4 Evaluation Board is based on the RV1103B SoC and has:

- 256 MB of RAM
- 256 MB of SPI-NAND
- Ethernet
- USB OTG
- Wifi
- SD card
- Camera connector

The details can be found at:
https://documentation.onioniot.com/omega4/getting-started/

Add the initial support for this board so that it can fully boot into Linux with the root file system stored in the SPI NAND.

nit: Is rv1103b needed in all three compatible strings? The last one is already pointing out that this is the rv1103b soc, also the other Onion Omega boards in-tree use onion,omega and onion,omega2+.

All the boards inside arch/arm/boot/dts/rockchip/Makefile start with the SoC name, so I prefer to be consistent.

I have addressed all of the other feedback you gave me and sent a v4.

All the boards inside arch/arm/boot/dts/rockchip/Makefile start with the SoC name, so I prefer to be consistent.

I do not follow, the .dts-filename typically do not fully follow the topmost compatible for the board on Rockchip platform.

The typical convention for Rockchip platform is:

compatible: "<vendor>,<board model>[-<revision>]",

             ["<vendor>,<som model>",]
             "rockchip,<soc>"

and the filename is typically:

board dts: <soc>-[<vendor>-]<board model>[-<revision>].dts som dtsi: <soc>-[<vendor>-]<som model>.dtsi
soc dtsi: <soc>.dtsi

The board model typically only include <soc> if there are multiple versions/revisions sharing same/similar model name.

And in mainline U-Boot we try to follow this convention for Rockchip defconfig naming:

defconfig: [<vendor>-]<board model>-<soc>_defconfig

So my question remains, why do the soc (rv1103b) name need to be repeated in all compatible parts? Is there expected to be another Onion Omega4 version/revision using a different Rockchip SoC?

And if that is the case, then probably only the SOM part would need the soc part, not the topmost part of the compatible.

Regards,
Jonas
