phy: Find the right match in devm_phy_destroy()

2015-04-13T12:03:53+00:00

commit 2f1bce487cd0a02623cff3d877940f9a2026341c upstream.

devm_phy_create() stores the pointer to the new PHY at the address
returned by devres_alloc(). The res parameter passed to devm_phy_match()
is therefore the location where the pointer to the PHY is stored, hence
it needs to be dereferenced before comparing to the match data in order
to find the correct match.

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.
