2015-08-03phy: Constify struct phy_ops variablesAxel Lin
The phy_ops variables are never modified after initialized in these drivers, so make them const. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Patrice Chotard <patrice.chotard@st.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
2015-03-12phy: exynos-dp-video: Kill exynos_dp_video_phy_pwr_isol functionAxel Lin
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.

2014-11-22phy: remove the old lookup methodHeikki Krogerus
The users of the old method are now converted to the new one. Signed-off-by: Heikki Krogerus <heikki.krogerus@linux.intel.com> [ kishon@ti.com : made phy-berlin-usb.c and phy-miphy28lp.c to use the updated devm_phy_create API.] Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
2014-09-24phy: remove .owner field for drivers using module_platform_driverPeter Griffin
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. Signed-off-by: Peter Griffin <peter.griffin@linaro.org> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
2014-09-24phy: exynos-dp-video: Use syscon support to control pmu registerVivek Gautam
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.

2014-07-22phy: core: Let node ptr of PHY point to PHY and not of PHY providerKishon Vijay Abraham I
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.

2014-02-18phy: let phy_provider_register be the last step in registering PHYKishon Vijay Abraham I
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.
