usb: phy: Add interface to get phy give of device_node.

2015-05-26T15:42:28Z

Split the "get phy from device_node" functionality out of "get phy by phandle" so it can be used directly. This is useful when a battery-charger is intimately associated with a particular phy but handled by a separate driver. The charger can find the device_node based on sibling relationships without the need for a redundant declaration in the devicetree description. As a peripheral that gets a phy will often want to register a notifier block, and de-register it later, that functionality is included so the de-registration is automatic.

usb: phy: Find the right match in devm_usb_phy_match

2015-03-19T16:28:14Z

The res parameter passed to devm_usb_phy_match() is the location where the pointer to the usb_phy is stored, hence it needs to be dereferenced before comparing to the match data in order to find the correct match.

usb: phy: never defer probe in non-OF case

2015-01-19T18:50:27Z

In practice failure to find phy when requested in non-OF case means it will never become available, so __usb_find_phy() must return -ENODEV and not -EPROBE_DEFER. This fixes a regression caused by commit 9c9d82492b73 (usb: phy: Fix deferred probing), where the USB controller driver is left infinitely into deferred probe when there are no phys.

usb: phy: Fix deferred probing

2015-01-09T20:40:37Z

Commit 1290a958d48e ("usb: phy: propagate __of_usb_find_phy()'s error on failure") actually broke the deferred probing mechanism, since it now returns EPROBE_DEFER only when the try_module_get call fails, but not when the phy lookup does. All the other similar functions seem to return ENODEV when try_module_get fails, and the error code of either __usb_find_phy or __of_usb_find_phy otherwise. In order to have a consistent behaviour, and a meaningful EPROBE_DEFER, always return EPROBE_DEFER when __(of_)usb_find_phy fails to look up the requested phy, that will be propagated by the caller, and ENODEV if try_module_get fails.

usb: phy: Restore deferred probing path

2014-12-23T18:37:16Z

Commit 1290a958d48e ("usb: phy: propagate __of_usb_find_phy()'s error on failure") broke platforms that rely on deferred probing to order probing of PHY and host controller drivers. The reason is that the commit simply propagates errors from __of_usb_find_phy(), which returns -ENODEV if no PHY has been registered yet for a given device tree node. The only case in which -EPROBE_DEFER would now be returned is if try_module_get() did fail, which does not make sense. The correct thing to do is to return -EPROBE_DEFER if a PHY hasn't been registered yet. The only condition under which it makes sense to return -ENODEV is if the device tree node representing the PHY has been disabled (via the status property) because in that case the PHY will never be registered. This patch addresses the problem by making __of_usb_find_phy() return an appropriate error code while keeping in line with the above-mentioned commit to propagate error codes rather than overwriting them. At the same time the check for a valid PHY is decoupled from the check for the try_module_get() call and a separate error code is returned if the latter fails.

usb: phy: introduce usb_phy_set_event interface

2014-11-21T15:05:45Z

PHY drivers require a generic interface to handle per-PHY events. usb_phy_set_event interface sets event to phy event. PHY drivers call this interface for each phy event.

usb: phy: propagate __of_usb_find_phy()'s error on failure

2014-11-20T19:43:22Z

When __of_usb_find_phy() fails, it returns -ENODEV - its error code has to be returned by devm_usb_get_phy_by_phandle(). Only when the former function succeeds and try_module_get() fails should -EPROBE_DEFER be returned.
