This patch adds a glue platform driver for the Synopsys G210 Test Chip.

Looks basically ok, but I think it can be simplified a little:

+/**
+ * struct ufs_hba_dwc_vops - UFS DWC specific variant operations
+ */
+static struct ufs_hba_variant_ops tc_dwc_g210_pltfm_hba_vops = {
+	.name                   = "tc-dwc-g210-pltfm",
+	.link_startup_notify	= ufshcd_dwc_link_startup_notify,
+};
+
+/**
+ * tc_dwc_g210_pltfm_probe()
+ * @pdev: pointer to platform device structure
+ *
+ */
+static int tc_dwc_g210_pltfm_probe(struct platform_device *pdev)
+{
+	int err;
+	struct device *dev = &pdev->dev;
+	struct device_node *np = dev->of_node;
+
+	/* Check Test Chip type and set the specific setup routine */
+	if (of_device_is_compatible(np, "snps, g210-tc-6.00-20bit")) {
+		tc_dwc_g210_pltfm_hba_vops.custom_phy_initialization =
+						tc_dwc_g210_config_20_bit;
+	} else if (of_device_is_compatible(np, "snps, g210-tc-6.00-40bit")) {
+		tc_dwc_g210_pltfm_hba_vops.custom_phy_initialization =
+						tc_dwc_g210_config_40_bit;
+	}

Instead of manually checking the compatible string, define two copies
of the ufs_hba_variant_ops, and put a pointer to them into the
.data field of tc_dwc_g210_pltfm_match.
