[PATCH v2 02/12] usb: chipidea: permit driver bindings pass phy pointer

Richard Zhao [off-list ref] writes:

Hi,

Sometimes, the driver bindings may know what phy they use.
For example, when using device tree, the usb controller may have a
phandler pointing to usb phy.

Some comments below:

[snip]

 	ci->dev = dev;
 	ci->udc_driver = dev->platform_data;
+	if (ci->udc_driver->phy)
+		ci->transceiver = ci->udc_driver->phy;
+	else
+		ci->global_phy = 1;

Nitpick: since it's a bool, don't you want to use "true" instead?

[snip]

+#include <linux/usb/otg.h>
+
 struct ci13xxx;
 struct ci13xxx_udc_driver {
 	const char	*name;
 	/* offset of the capability registers */
 	uintptr_t	 capoffset;
 	unsigned	 power_budget;
+	struct usb_phy	*phy;

This structure is really platform information, not per-device
instance. Consider, for example, situation when you have 2 controllers
in one system, they'll be using the same platform structure, but they'll
have different phys. Right?
