phy: remove the old lookup method

2014-11-22T08:28:39+00:00

The users of the old method are now converted to the new one.

phy: improved lookup method

2014-11-21T14:18:50+00:00

Separates registration of the phy and the lookup. The method
is copied from clkdev.c,

phy: phy-core: use the np present in of_phandle_args to get the PHY

2014-11-12T13:10:13+00:00

Instead of using the node pointer of the PHY provider and then scanning its
child nodes to get a reference to the PHY, directly use the node pointer
present in of_phandle_args to get a reference to the PHY.

phy: core: Let node ptr of PHY point to PHY and not of PHY provider

2014-07-22T07:16:11+00:00

In case of multi-phy PHY providers, each PHY should be modeled as a sub
node of the PHY provider. Then each PHY will have a different node pointer
(node pointer of sub node) than that of PHY provider. Added this provision
in the PHY core.
Also fixed all drivers to use the updated API.

phy: core: Fix of_phy_provider_lookup to return PHY provider for sub node

2014-07-22T07:16:11+00:00

Fixed of_phy_provider_lookup to return 'phy_provider' if _of_phy_get
passes the node pointer of the sub-node of phy provider node. This is
needed when phy provider implements multiple PHYs and each PHY is
modelled as the sub-node of PHY provider device node.

phy: core: Support regulator supply for PHY power

2014-07-22T07:16:10+00:00

Some PHYs can be powered by an external power regulator.
e.g. USB_HS PHY on DRA7 SoC. Make the PHY core support a
power regulator.

phy: core: Fix error path in phy_create()

2014-07-12T01:23:49+00:00

Prevent resources from being freed twice in case device_add() call
fails within phy_create(). Also use ida_simple_remove() instead of
ida_remove() as we had used ida_simple_get() to allocate the ida.

phy: fix kernel oops in phy_lookup()

2014-04-24T19:53:38+00:00

The kernel oopses in phy_lookup() due to 'phy->init_data' being NULL if we
register PHYs from a device tree probing driver and then call phy_get() on a
device that has no representation in the device tree (e.g. a PCI device).
Checking the pointer before dereferening it and skipping an interation if
it's NULL prevents this kernel oops.

phy: core: Add devm_of_phy_get to phy-core

2014-03-08T07:09:43+00:00

Adding devm_of_phy_get will allow to get phys by supplying a
pointer to the struct device_node instead of struct device.

phy: core: Add an exported of_phy_get function

2014-03-08T07:09:42+00:00

Previously the of_phy_get function took a struct device * and
was declared static. It was impossible to call it from
another driver and thus it was impossible to get phy defined
for a given node. The old function was renamed to _of_phy_get
and was left for internal use. of_phy_get function was added
and it was exported. The function enables to get a phy for
a given device tree node.
