usb: phy: Find the right match in devm_usb_phy_match

2015-05-06T19:59:11+00:00

commit 869aee0f31429fa9d94d5aef539602b73ae0cf4b upstream.

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: move some error messages to debug

2014-02-04T20:59:14+00:00

the PHY layer is supposed to be optional,
considering some PHY have no control bus
for SW to poke around.

After commit 1ae5799 (usb: hcd: Initialize
USB phy if needed) any HCD which didn't provide
a PHY driver would emit annoying error messages.

In this patch we're decreasing those messages
to debugging only and we also add a PHY prefix
or use dev_dbg so we know where they're coming from.

usb: phy: initialize the notifier when add a new phy

2013-12-12T19:43:34+00:00

We need to initialize the notifer before use it.

So lets initialize it when add a new phy device to
reduce the code redundancy.

usb: phy: don't return with NULL from devm_usb_get_phy()

2013-10-11T18:50:38+00:00

The callers are expecting an ERR_PTR value in case
of an error. Change he code to return with an encoded
-ENOMEM value in the case of a failed devres_alloc call.

usb: phy: remove exported function from __init section

2013-04-23T11:13:48+00:00

The symbol usb_bind_phy is exported and annotated __init.
It looks like section mismatch. Fix by removing the
__init annotation of usb_bind_phy.

usb: phy: convert EXPORT_SYMBOL to EXPORT_SYMBOL_GPL

2013-03-18T09:18:04+00:00

we only want GPL users for our generic functions,
so let's switch over to EXPORT_SYMBOL_GPL.

usb: phy: move bulk of otg/otg.c to phy/phy.c

2013-03-18T09:17:58+00:00

Most of otg/otg.c is not otg specific, but phy specific, so move it
to the phy directory.
