Power upstream增加 A210 的PINCTRL及电源管理驱动 by ifnfn · Pull Request #375 · RVCK-Project/rvck

ifnfn · 2026-08-26T05:28:16Z

本 PR 为 ZhiHe A210 增加 pinctrl、AON、mailbox、AON regulator 以及 power domain 相关支持，为后续 A210 平台上的外设电源管理和板级设备树使能提供基础能力。

主要内容包括：

增加 A210 pinctrl 设备树绑定和 pinctrl 驱动，用于描述并配置 A210 各 pad controller 的 pin mux 和 pin configuration
增加 A210 AON 子系统相关设备树绑定，包括 AON firmware、mailbox 和 AON regulator 接口描述
增加 A210 mailbox controller 驱动，用于 Linux 与 AON 固件之间的 IPC 通信
增加 A210 AON firmware 驱动及调试接口，用于加载并管理 AON 固件服务
增加基于 AON firmware 的 regulator provider，用于控制 A210 上由 AON 管理的电源 rail
增加 A210 power domain 设备树绑定和 power domain 驱动，用于管理 SoC 内部子系统的上电、下电和状态查询
在 A210 设备树中补充 pinctrl、AON 子系统以及 power domain 相关节点，并建立相关设备之间的 power-domain 关联

Fixed #373

1st review

`33be89f` dt-bindings: pinctrl: zhihe: add A210 pinctrl

bindings 中增加 description，介绍一下 a210 的 pin controller
缺乏对引脚配置的规格描述，目前只描述了 pin controller 的。具体可以参考 rvck 下的 thead,th1520-pinctrl.yaml 或者主线中较新的产品的 pintrl binding 文件，譬如 sophgo 和 spacemit 的。

`991a8bb` pinctrl: zhihe: add A210 pinctrl driver

drivers/pinctrl/Kconfig: default ARCH_ZHIHE 这个应该删除，作为一个支持 tristate 的模块来说一般默认为空，如果的确需要作为 m 或者 y 请修改 rvck_defconfig，而且尽量 m，y 会增加 Image 体积。
drivers/pinctrl/Makefile: 请按照 CONFIG 的字典顺序排列
checkpatch 报告 drivers/pinctrl/pinctrl-a210.c 中出现多处超长代码行，看看还能优化一下？实在不行就算了。

`425075a` dt-bindings: firmware: zhihe: add A210 AON subsystem

每个模块的 bindig 文件应该分开单独 patch 提交，所以这个补丁应该分成三个补丁 firmware/mailbox/regulator
Documentation/devicetree/bindings/mailbox/zhihe,a210-mailbox.yaml: 提到一个 "Local ICU CPU index" 的概念，建议在 description 中介绍一下 ICU 是什么意思，以及它和 mailbox 的关系。

`2c9c502` mailbox: zhihe: add A210 mailbox controller driver

drivers/mailbox/Kconfig: default ARCH_ZHIHE 这个应该删除，对于这些模块，参考上游的 Kconfig 大部分都不会设置默认值的，如果需要设置可以修改 rvck_defconfig。
drivers/mailbox/Makefile: 中间用 TAB 对齐。
drivers/mailbox/zhihe-mailbox.c:
- 文件名问题，这个 mailbox 驱动文件是只对 a210 还是考虑支持以后所有 zhihe 产品？
- include 的字典顺序
- 和文件名问题类似，代码中的宏命名、变量名、函数名的前缀是 zhihe 还是应该用 a210？
- 和文件名问题类似，代码中的驱动名字 "zhihe_mbox" 是否需要修改为 "a210_mbox" 或者 "zhihe_a210_mbox"

`cddb99d` firmware: zhihe: add A210 AON subsystem driver

drivers/firmware/zhihe/Kconfig: default ARCH_ZHIHE 这个应该删除，道理同上，如果需要设置可以修改 rvck_defconfig。
zhihe_proc_debug.h 这个文件为何放在 include/linux，建议放在 drivers/firmware/zhihe 下因为只有 drivers/firmware/zhihe/zhihe_aon.c 用到了。
drivers/firmware/zhihe/zhihe_aon.c：
- include 的字典顺序
- 类似前面提到的文件名问题，这个 aon 驱动文件是只对 a210 还是考虑支持以后所有 zhihe 产品？
- 类似前面提到的代码中的宏命名、变量名、函数名的前缀问题
- 类似前面提到的驱动名字问题 "zhihe-aon"
include/linux/firmware/zhihe/a210-ipc.h:
- zhihe_aon_misc_set_control 和 zhihe_aon_misc_get_control 没有定义，请删掉。
- 为何 include thead,th1520-aon.h，建议剥离。

`9b4c017` regulator: zhihe: add A210 AON regulator driver

drivers/regulator/Kconfig:
- 请确认一下名字，注释中是否要加上 A210
- default ZHIHE_AON 的问题，同上
drivers/regulator/zhihe-aon-regulator.c:
- 类似前面提到的文件名问题, 宏命名、变量名、函数名的前缀问题，以及驱动名字问题 "zhihe-aon-reg"
- 这个驱动的实现为何依赖于 th1520？复用了大量的 th1520 的结构体和宏，建议清理剥离掉。

`63ebcdb` dt-bindings: power: zhihe: add A210 power domains

每个模块的 bindig 文件应该分开单独 patch 提交，所以这个补丁应该分成 2 个补丁, clock/pm
“Documentation/devicetree/bindings/clock/zhihe,a210-ccu.yaml” 中的 description 部分，最后一句话 ”the system functions correctly without CCU nodes present“ 是想表达这个 ccu 节点是可选的吗？对于 A210 来说应该是有 CCU ip 的，设备树的用途就是描述硬件，所以如果 A210 中一定有 ccu 模块的话，我理解不存在可选的问题，所以这句话是否可以删去？或者你是想表达 CCU 的功能可以关闭？如果是这样我觉得可以换个说法，而且如何关闭呢，从 binding 上我没有看出来。

`9c8ba95` pmdomain: zhihe: add A210 power domain support

drivers/pmdomain/zhihe/Kconfig: default ARCH_ZHIHE 的问题，同上。

`e2911db` (HEAD -> pr-375-review) riscv: dts: zhihe: add A210 power domains

请在 commit message 中解释一下为何针对 dev board 要 /delete-property/ 和 /delete-node/

2nd review

p.s. 因为今天恰逢月底要锁版本做 release，如果来不及更新，建议等新的 rvck-6.6 发出来后再做 rebase，这个 pr 主要是 bsp 改动，应该 rebase 很方便的。

`a322f72` dt-bindings: mailbox: zhihe: add A210 mailbox controller

zhihe,a210-mailbox.yaml 中的 description 部分

Mailbox controller for the Zhihe A210 SoC providing inter-processor
communication channels between the application processor and other
cores such as the AON (Always-On) subsystem.

中 providing 应该是 provides。另外我不确定这里把 AON 称为 cores 是不是容易引起误解，cores 应该指的是处理器核心吧，是否可以改成：other subsystem such as the AON

the mailbox generates for that processor. The zhihe,icu-cpu-id
property tells the driver which ICU, i.e. which local processor,

这里的 The zhihe,icu-cpu-id property 建议改成 The property "zhihe,icu-cpu-id"

`932f083` dt-bindings: regulator: zhihe: add A210 AON regulator

zhihe,a210-aon-regulator.yaml 中的 description 部分

Each supported rail is described by a child node. The
zhihe,regulator-id property identifies the corresponding AON firmware

这里的 The zhihe,regulator-id property 建议改成 The property "zhihe,regulator-id property"。

`767110d` mailbox: zhihe: add A210 mailbox controller driver

checkpatch 会报 CHECK: Alignment should match open parenthesis，这些告警应该可以去掉。

`288e121` firmware: zhihe: add A210 AON subsystem driver

我看你 config ZHIHE_PROC_DEBUG 中 depends on ZHIHE_A210_AON=y。ZHIHE_A210_AON 是 tristate，如果它被配置为 m（模块），则 ZHIHE_A210_AON=y 为假，当前选项会完全隐藏。我理解 ZHIHE_PROC_DEBUG 只是一个调试开关，和 AON 是 y 或者 m 并不关联，如果你这么写，用户在设置 AON 为模块时无法开启调试功能，可能不符合预期，你确定要做成这样？
zhihe_proc_debug.c 中 include 的字典顺序
zhihe_remove_panic_log_proc 这个函数没有使用者，确定要保留以及需要导出？
checkpatch 会报 CHECK: Alignment should match open parenthesis，这些告警应该可以去掉。

`e2630b0` regulator: zhihe: add A210 AON regulator driver

checkpatch 会报 CHECK: Alignment should match open parenthesis，这些告警应该可以去掉。
