phy: Add set_mode callback

2016-07-04T11:49:22+00:00

The initial use for this is for PHYs that have a mode related to USB OTG.
There are several SoCs (e.g. TI OMAP and DA8xx) that have a mode setting
in the USB PHY to override OTG VBUS and ID signals.

Of course, the enum can be expaned in the future to include modes for
other types of PHYs as well.

phy: core: Allow children node to be overridden

2016-04-29T14:39:39+00:00

In order to more flexibly support device tree bindings, allow drivers to
override the container of the child nodes. By default the device node of
the PHY provider is assumed to be the parent for children, but bindings
may decide to add additional levels for better organization.

phy: core: fix wrong err handle for phy_power_on

2016-02-10T06:15:41+00:00

If phy_pm_runtime_get_sync failed but we already
enable regulator, current code return directly without
doing regulator_disable. This patch fix this problem
and cleanup err handle of phy_power_on to be more readable.

phy: core: Get a refcount to phy in devm_of_phy_get_by_index()

2015-12-07T13:14:02+00:00

On driver detach, devm_phy_release() will put a refcount to
the phy, so gets a refconut to it before return.

Merge 4.1-rc7 into usb-next

2015-06-08T17:57:51+00:00

This resolves a merge issue in musb_core.c and we want the fixes that
were in Linus's tree in this branch as well for testing.

phy: core: Check requested PHY status in _of_phy_get()

2015-05-11T16:12:27+00:00

This is a common checking in various drivers, so move the checking to
_of_phy_get().

phy: phy-core: allow specifying supply at port level

2015-05-11T16:12:25+00:00

Multi-port phys may have per port power supplies. Let's change phy
core to look for supply at the port level when multiple ports are
specified. To keep compatibility with the existing device tree board
descriptions for single-port phys we will continue looking up the
power supply at the parent node level

phy: core: Add devm_of_phy_get_by_index to phy-core

2015-05-11T16:12:23+00:00

Some generic drivers, such as ehci, may use multiple phys and for such
drivers referencing phy(s) by name(s) does not make sense. Instead of
inventing new naming schemes and using custom code to iterate through them,
such drivers are better of using nameless phy bindings and using this newly
introduced API to iterate through them.

phy: core: Fix error checking in (devm_)phy_optional_get

Don't pass valid pointer to PTR_ERR, use PTR_ERR(phy) only when
IS_ERR(phy) is true.
