[PATCH 6/6] cpufreq: probe the Integrator cpufreq driver from DT

[adding devicetree to Cc]

Hi Linus,

[...]

+static int __init integrator_cpufreq_probe(struct platform_device *pdev)
 {
+	struct device_node *np = pdev->dev.of_node;
+
+	cm_base = of_iomap(np, 0);
+	if (!cm_base)
+		return -ENODEV;
 	return cpufreq_register_driver(&integrator_driver);

If we fail to register the driver we could unmap cm_base, no?

 }
 
-static void __exit integrator_cpu_exit(void)
+static void __exit integrator_cpufreq_remove(struct platform_device *pdev)
 {
 	cpufreq_unregister_driver(&integrator_driver);

Unmap here?

 }
 
+static const struct of_device_id integrator_cpufreq_match[] = {
+	{ .compatible = "arm,core-module-integrator"},
+	{ },
+};

It feels a little scary that this also got handled by some other code in
the previous patch. Is no arbitrarion required between the two when
accessing the core module registers?

Cheers,
Mark.
