ZhiHe A210: add peripheral support (GPIO/timers/I2C/SPI/DMA) by ifnfn · Pull Request #382 · RVCK-Project/rvck

ifnfn · 2026-08-31T07:44:34Z

Add peripheral support for the ZhiHe A210 SoC: GPIO, DW APB timers, I2C, SPI and DMA (dw-axi-dmac) bindings/drivers and device trees.

Tracked by #381.

Note: this branch is stacked on top of the A210 pinctrl/power series (#375). Once #375 is merged and this branch rebased, the diff will narrow down to the 8 peripheral commits:

dt-bindings: gpio: snps,dw-apb: add ZhiHe A210
dt-bindings: dma: snps,dw-axi-dmac: add ZhiHe A210
dmaengine: dw-axi-dmac: add ZhiHe A210 support
riscv: dts: zhihe: add A210 GPIO controllers
riscv: dts: zhihe: add A210 DW APB timers
riscv: dts: zhihe: add A210 I2C controllers
riscv: dts: zhihe: add A210 SPI controllers
riscv: dts: zhihe: add A210 DMA controller

1st review:

commit message 中的 bugzilla 写错了

应该是 issue 381，写成了 382，这个问题所有的 commit 都有，请一起改正。

`046c972` riscv: dts: zhihe: add A210 DMA controller

commit 的描述不准确

Describe the ZhiHe A210 AXI DMAC node and board DMA usage.

a210.dtsi 应该是 SoC 级别的文件，不会涉及 board DMA usage。直接说 Add the dma controller node for the ZhiHe A210 SoC. 就好，当然如果 commit 中能简单一句话介绍一下 A210 的 DMA 情况会更好。这个问题对于其他几个 dtsi 的补丁希望都调整一下。

`ea0f6cf` riscv: dts: zhihe: add A210 GPIO controllers

建议把 dts 的修改和 dtsi 的修改分成两个独立的补丁，这样以后一旦需要 revert 也会方便一些。

同时描述上也对 SoC（某个外设控制器）和 board 的行为做些描述，一两句话点到即可，否则目前这样 "Describe xxx" 的描述其实对希望了解 A210 和开发板的人来说实在没有什么太大帮助。

另外，对于存在外接的 SoC 外设，社区推荐 “SoC 默认 disabled，Board 按需 enable”，参考 https://lore.kernel.org/linux-riscv/1561455091-29488-1-git-send-email-yash.shah@sifive.com/。请对照再修改一下, 譬如 GPIO, I2C，SPI。另外我想起来 UART 最好也是按照这个规则改一下。方便的话在这次加个 commit 改一下 uart？

2nd review

请在 PR 中补充有关 dev 开发板改名的信息

这些修改是你第二次新加的吧，请补上描述。

`28ef691` riscv: dts: zhihe: rename A210 development board to Melon Pi

建议将 dts 文件命名为 a210-melon-pi.dts, 参考上游的 dts 文件的命名规范：<soc_name>-<board_name>.dts

`d55bf48` riscv: dts: zhihe: enable GPIO controllers on A210 boards

commit 描述中还是使用 development 的描述，应该改成 melon-pi 了

`baa88e3` riscv: dts: zhihe: disable unused A210 UARTs by default

commit 描述中还是使用 development 的描述，应该改成 melon-pi 了

`d064795` riscv: dts: zhihe: enable DMA and timers on A210 boards

这个补丁没必要，一般情况下，我们对 I2C、SPI、UART、GPIO、I2S、PWM、CAN 等这些外设在 .dtsi（SoC 级）里会默认关闭，因为这些外设功能常常涉及引脚复用，所以默认关闭避免冲突，在具体板级 dts 上根据需要使能。而对于 DMA controller、timer、interrupt-controller（GIC）、clock controller 等这些相对底层的公共资源，在 SoC 上常常被其他外设依赖，所以默认都是开着的，在 dtsi 上不写，默认 status 就是 okay 的。
