phy: Group vendor specific phy drivers

2017-06-01T09:58:33Z

Adding vendor specific directories in phy to group phy drivers under their respective vendor umbrella. Also updated the MAINTAINERS file to reflect the correct directory structure for phy drivers.

phy: omap-usb2: support suspend/resume

2016-09-10T11:18:39Z

Relying on PM-ops for shutting down PHY clocks was a bad idea since the users (e.g. USB DWC3) might not have been suspended by then. Get rid of all PM-ops. It is the sole responsibility of the PHY user to properly turn OFF and de-initialize the PHY as part of its suspend routine. Enable/disable PHY clock as part of ->init()/->exit() call respectively. With this phy_init() and phy_exit() can be called by PHY user during suspend/resume. This is similar to what is done for ti-pipe3 driver. See 31c8954efb1b ("phy: ti-pipe3: fix suspend") The pm_runtime_enable() call in omap_usb2_probe() is still required because without it, phy_create() will not enable runtime PM on the phy device it creates and phy_init() will not call pm_runtime_get_sync(). Without pm_runtime_get_sync(), ocp2scp hwmod will _not_ enable the IP and, thus, we will have abort exceptions.

phy: omap-usb2: use syscon framework API to power on/off the PHY

2015-12-21T08:56:28Z

Deprecate using phy-omap-control driver to power on/off the PHY, and use *syscon* framework to do the same. This handles powering on/off the PHY for the USB2 PHYs used in various TI SoCs. Signed-off-by: Kishon Vijay Abraham I

phy: omap-usb2: use omap_usb_power_off to power off the PHY during probe

2015-12-21T08:56:28Z

No functional change. Previously omap_control_phy_power() was used to power off the PHY during probe. But once phy-omap-usb2 driver is adapted to use syscon, omap_control_phy_power() cannot be used. Hence used omap_usb_power_off to power off the PHY. Signed-off-by: Kishon Vijay Abraham I Acked-by: Roger Quadros

phy: Constify struct phy_ops variables

2015-08-03T13:05:09Z

The phy_ops variables are never modified after initialized in these drivers, so make them const. Signed-off-by: Axel Lin Acked-by: Patrice Chotard Signed-off-by: Kishon Vijay Abraham I

phy: omap-usb2: invoke pm_runtime_disable on error path

2015-05-12T15:27:19Z

if devm_clk_get for wkupclk fails, there will be an unbalanced pm_runtime_enable. Fix it here. Reported-by: Benoit Parrot Cc: Roger Quadros Signed-off-by: Kishon Vijay Abraham I

phy: omap-usb2: Fix missing clk_prepare call when using old dt name

2015-03-13T11:44:39Z

Current code does not call clk_prepare(phy->optclk) when using the old usb_otg_ss_refclk960m name. Fix it. Signed-off-by: Axel Lin Signed-off-by: Kishon Vijay Abraham I

phy: omap-usb2: Remove unneeded ifdef CONFIG_OF guard and of_match_ptr

2015-03-10T08:42:27Z

if !CONFIG_OF, the probe fails. This is a dt-only driver, so the ifdef CONFIG_OF guard and of_match_ptr are not needed. Signed-off-by: Axel Lin Signed-off-by: Kishon Vijay Abraham I
