Corrected spelling of 'Powero ff' to 'Power off' in error message. / 将错误消息中的 'Powero ff' 拼写更正为 'Power off'。

Suggested change

+    {
+        if (!rt_strcmp(spacemit_pmic_pinctrl_params[i].propname, "name"))


String comparison compares against literal "name" instead of the variable name, which will never match the intended property names. Should compare spacemit_pmic_pinctrl_params[i].propname against the parameter name. / 字符串比较使用了字面量 "name" 而不是变量 name，这将永远无法匹配预期的属性名称。应该将 spacemit_pmic_pinctrl_params[i].propname 与参数 name 进行比较。

Suggested change

if (!rt_strcmp(spacemit_pmic_pinctrl_params[i].propname, "name"))

if (!rt_strcmp(spacemit_pmic_pinctrl_params[i].propname, name))

+        pc->dcr_fd = rt_dm_dev_prop_read_bool(dev, "rcpu-pwm") ? 1 : 0;


This line overwrites the pc->dcr_fd value that was just set on line 242. The second assignment should likely be setting pc->rcpu_pwm instead of pc->dcr_fd again. / 这一行覆盖了刚在第 242 行设置的 pc->dcr_fd 值。第二次赋值应该设置 pc->rcpu_pwm 而不是再次设置 pc->dcr_fd。

Suggested change

pc->dcr_fd = rt_dm_dev_prop_read_bool(dev, "rcpu-pwm") ? 1 : 0;

pc->rcpu_pwm = rt_dm_dev_prop_read_bool(dev, "rcpu-pwm") ? 1 : 0;

+    if (rt_is_err(spi->clk))

Error check uses spi->clk but should check spi->rstc after the reset control assignment on line 975. / 错误检查使用了 spi->clk 但应该在第 975 行的复位控制赋值后检查 spi->rstc。

Suggested change

Debug tag incorrectly says "mailbox.rockchip" but this is Spacemit K1X mailbox driver, not Rockchip. Should be "mailbox.spacemit" or "mailbox.k1x". / 调试标签错误地写为 "mailbox.rockchip"，但这是 Spacemit K1X 邮箱驱动程序，而不是 Rockchip。应该是 "mailbox.spacemit" 或 "mailbox.k1x"。

Debug level is set to DBG_LOG which is unusual for production code. Consider using DBG_INFO or DBG_WARNING for consistency with other drivers in this BSP. / 调试级别设置为 DBG_LOG，这在生产代码中并不常见。考虑使用 DBG_INFO 或 DBG_WARNING 以与此 BSP 中的其他驱动程序保持一致。
