Hello,
+static int mt7620_gsw_probe(struct platform_device *pdev)
+{
+ struct resource *res = platform_get_resource(pdev, IORESOURCE_MEM, 0);
+ const char *port4 = NULL;
+ struct mt7620_gsw *gsw;
+ struct device_node *np;
+
+ gsw = devm_kzalloc(&pdev->dev, sizeof(struct mt7620_gsw), GFP_KERNEL);
+ if (!gsw)
+ return -ENOMEM;
+
+ gsw->base = devm_ioremap_resource(&pdev->dev, res);
+ if (!gsw->base)
+ return -EADDRNOTAVAIL;
+
+ gsw->dev = &pdev->dev;
+
+ of_property_read_string(np, "mediatek,port4", &port4);
+ if (port4 && !strcmp(port4, "ephy"))
+ gsw->port4 = PORT4_EPHY;
+ else if (port4 && !strcmp(port4, "gmac"))
+ gsw->port4 = PORT4_EXT;
+ else
+ gsw->port4 = PORT4_EPHY;
+
Where device_node structure is populated? CC uses of_find_matching_node,
but in DD/trunk this structure is null, and I cannot set "mediatek,port4"
property to gmac.
