2015-08-03phy: Constify struct phy_ops variablesAxel Lin1-1/+1
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>

2015-03-26phy: exynos5-usbdrd: Add to support for Exynos5433 SoCJaewon Kim1-0/+10
This patch adds driver data to support for Exynos5433 SoC. The Exynos5433 has one USB3.0 Host and USB3.0 DRD(Dual Role Device). Exynos5433 is simplar to Eyxnos7 but Exynos5433 have one more USB3.0 Host controller. Signed-off-by: Jaewon Kim <jaewon02.kim@samsung.com> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
2015-03-13phy: exynos5-usbdrd: Fix off-by-one valid value checking for args->args[0]Axel Lin1-1/+1
Current code uses args->args[0] as array subscript of phy_drd->phys[]. So the valid value range for args->args[0] is 0 ... EXYNOS5_DRDPHYS_NUM - 1.

2014-11-22phy: exynos5-usbdrd: Add facility for VBUS-BOOST-5V supplyVivek Gautam1-2/+30
Some Exynos boards have a separate regulator controlling a Boost 5V supply which goes as input for VBUS regulator. So adding a control for the same in driver, to enable vbus supply on the port.

2014-11-22phy: exynos5-usbdrd: Add pipe-clk, utmi-clk and itp-clk supportVivek Gautam1-18/+86
Exynos7 SoC has now separate gate control for 125MHz pipe3 phy clock, as well as 60MHz utmi phy clock. Additionally, separate gate control is available for the clock used for ITP (Isochronous Transfer Packet) generation. So get the same and control in the phy-exynos5-usbdrd driver.

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 Griffin1-1/+0
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>
2014-08-28phy: exynos5-usbdrd: Add MODULE_DEVICE_TABLE entrySjoerd Simons1-0/+1
Add a MODULE_DEVICE_TABLE call for OF match tables. This allows the module to be autoloaded based on devicetree information. Signed-off-by: Sjoerd Simons <sjoerd.simons@collabora.co.uk> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com>
2014-07-22phy: core: Let node ptr of PHY point to PHY and not of PHY providerKishon Vijay Abraham I1-1/+2
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.

2014-05-13phy: Add new Exynos5 USB 3.0 PHY driverVivek Gautam1-0/+644
Add a new driver for the USB 3.0 PHY on Exynos5 series of SoCs. The new driver uses the generic PHY framework and will interact with DWC3 controller present on Exynos5 series of SoCs. Also, created a new header file in linux/mfd/syscon/ for Exynos5 SoCs and put the required PMU offset definitions for the basic available PHYs.
