我使用   https://git.ti.com/gitweb?p=ti-analogue-linux-kernel/analogue-linux.git;a=blob;f=drivers/net/phy/dp83tc812.c;h=0c594375f188d40299603628a0636947cfea35bf;hb=f973f3deb81b1f44aa4c33b275a342e28fc982fd 中的 dp83tc812.c 文件

它显示构建错误：

此驱动程序有一个明显的错误，即缺少"phydev->priv = dp83720；"：

static int dp83812_probe(struct phy_device *phydev)
{
	struct dp83812_private *dp83812;
	int ret;

	dp83812 = devm_kzalloc(&phydev->mdio.dev, sizeof(*dp83812), GFP_KERNEL);
	if (!dp83812)
		return -ENOMEM;
		
	phydev->priv = dp83720;   //lack of this, it will case coredump.

	ret = dp83812_read_straps(phydev);
	if (ret)
		return ret;

	switch (phydev->phy_id) {
	case DP83TC812_CS1_0_PHY_ID:
		dp83812->chip = DP83812_CS1;
	break;
	case DP83TC812_CS2_0_PHY_ID:
		dp83812->chip = DP83812_CS2;
	break;
	case DP83TC813_CS2_0_PHY_ID:
		dp83812->chip = DP83813_CS2;
		break;
	case DP83TC814_CS2_0_PHY_ID:
		dp83812->chip = DP83814_CS2;
	break;
	default:
	return -EINVAL;
	};
/* vikram : above code added to switch between different phy ids */

	return dp83812_config_init(phydev);
}

1.在我的 SDK 中、'ack_interrupt'不存在、构建失败、所以我将其删除、打开'handle_interrupt = dp83812_handle_interrupt'。 我可以这么做吗？

2.有了最新的驱动程序,phy 运行良好,您能提供'DP.83TG720S-Q1'驱动程序吗?

我发现问题，这里是一个新的驱动程序，我们已经测试可在内核5.10上运行。 [/报价]

非常感谢您的支持。

您好、Zheng、  

很高兴你能来这里。
