usb: common: Consider only available nodes for dr_mode

2019-04-03T04:24:19+00:00

commit 238e0268c82789e4c107a37045d529a6dbce51a9 upstream.

There are cases where multiple device tree nodes point to the
same phy node by means of the "phys" property, but we should
only consider those nodes that are marked as available rather
than just any node.

USB: Fix of_usb_get_dr_mode_by_phy with a shared phy block

2016-06-21T07:52:39+00:00

Some SoCs have a single phy-hw-block with multiple phys, this is
modelled by a single phy dts node, so we end up with multiple
controller nodes with a phys property pointing to the phy-node
of the otg-phy.

Only one of these controllers typically is an otg controller, yet we
were checking the first controller who uses a phy from the block and
then end up looking for a dr_mode property in e.g. the ehci controller.

This commit fixes this by adding an arg0 parameter to
of_usb_get_dr_mode_by_phy and make of_usb_get_dr_mode_by_phy
check that this matches the phandle args[0] value when looking for
the otg controller.

Merge branch 'akpm' (patches from Andrew)

2016-03-19T02:26:54+00:00

Merge second patch-bomb from Andrew Morton:

 - a couple of hotfixes

 - the rest of MM

 - a new timer slack control in procfs

 - a couple of procfs fixes

 - a few misc things

 - some printk tweaks

 - lib/ updates, notably to radix-tree.

 - add my and Nick Piggin's old userspace radix-tree test harness to
   tools/testing/radix-tree/.  Matthew said it was a godsend during the
   radix-tree work he did.

 - a few code-size improvements, switching to __always_inline where gcc
   screwed up.

 - partially implement character sets in sscanf

usb: common: convert to use match_string() helper

2016-03-17T22:09:34+00:00

The new helper returns index of the mathing string in an array.  We
would use it here.

usb: define USB_SPEED_SUPER_PLUS speed for SuperSpeedPlus USB3.1 devices

2016-01-25T04:16:52+00:00

Add a new USB_SPEED_SUPER_PLUS device speed, and make sure usb core can
handle the new speed.
In most cases the behaviour is the same as with USB_SPEED_SUPER SuperSpeed
devices. In a few places we add a "Plus" string to inform the user of the
new speed.

usb: of: add an api to get dr_mode by the phy node

2015-12-15T15:12:41+00:00

Some USB phy drivers have different handling for the controller in each
dr_mode. But the phy driver does not have visibility to the dr_mode of
the controller.

This adds an api to return the dr_mode of the controller which
associates the given phy node.

usb: Rename usb-common.c

2014-09-25T15:02:34+00:00

In the next commit, we will want the usb-common module to be composed of
two object files. Since Kbuild cannot "append" another object to an
existing one, we need to rename usb-common.c to something
else (common.c) and create usb-common.o by linking the wanted objects
together. Currently, usb-common.o comprises only common.o.
