phy: Constify struct phy_ops variables

2015-08-03T13:05:09+00:00

The phy_ops variables are never modified after initialized in these
drivers, so make them const.

phy: exynos-dp-video: Kill exynos_dp_video_phy_pwr_isol function

2015-03-12T05:31:15+00:00

If IS_ERR(state->regs) the .probe fails.
So IS_ERR(state->regs) test in exynos_dp_video_phy_pwr_isol() is not necessary.
exynos_dp_video_phy_pwr_isol() simply does a regmap_update_bits() call now,
just call regmap_update_bits() instead and return proper return value.

phy: remove .owner field for drivers using module_platform_driver

2014-09-24T09:48:34+00:00

This patch removes the superflous .owner field for drivers which
use the module_platform_driver or platform_driver_register api,
as this is overriden in __platform_driver_register.

phy: exynos-dp-video: Use syscon support to control pmu register

2014-09-24T09:48:34+00:00

Currently the DP_PHY_ENABLE register is mapped in the driver,
and accessed to control power to the PHY.
With mfd-syscon and regmap interface available at our disposal,
it's wise to use that instead of using a 'reg' property for the
controller and allocating a memory resource for that.

To facilitate this, we have added another compatible string
for Exynso5420 SoC to acquire driver data which contains
different DP-PHY-CONTROL register offset.

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: let phy_provider_register be the last step in registering PHY

2014-02-18T20:13:16+00:00

Registering phy_provider before creating the PHY can result in PHY
callbacks being invoked which will lead to aborts. In order to avoid this
invoke phy_provider_register after phy_create and phy_set_drvdata.
