Probably qemu-malta has clk support disabled, so: static inline struct clk *clk_get(struct device_d *dev, const char *id) { return NULL; } Which is a valid clk and the driver is happy. clk_get_rate(priv->clk) returns 0 and the drivers continues with: if (priv->plat.clock == 0 && IS_ENABLED(CONFIG_OFDEVICE)) { struct device_node *np = dev->device_node; of_property_read_u32(np, "clock-frequency", &priv->plat.clock); } Which will read the correct clock-frequency from the device tree.
