usb: phy: change some comments

2015-01-12T18:13:28Z

- Delete the OTG stuffs - .set_suspend is for controller, not for A-device or B-device. Signed-off-by: Peter Chen Signed-off-by: Felipe Balbi

usb: phy: introduce usb_phy_set_event interface

2014-11-21T15:05:45Z

PHY drivers require a generic interface to handle per-PHY events. usb_phy_set_event interface sets event to phy event. PHY drivers call this interface for each phy event.

usb: move the OTG state from the USB PHY to the OTG structure

2014-11-03T16:01:25Z

Before using the PHY framework instead of the USB PHY one, we need to move the OTG state into another place, since it won't be available when USB PHY isn't used. This patch moves the OTG state into the OTG structure, and makes all the needed modifications in the drivers using the OTG state.

usb: phy: Add set_wakeup API

2014-03-05T20:40:08Z

This API is used to set wakeup enable at PHY registers, in that case, the PHY can be waken up from suspend due to external events, like vbus change, dp/dm change and id change. Signed-off-by: Peter Chen Signed-off-by: Felipe Balbi

usb: phy: protect against NULL phy pointers

2013-07-29T10:56:45Z

In order to decrease the amount of work done by PHY users, allow NULL phy pointers to be passed. Signed-off-by: Felipe Balbi

usb: add devicetree helpers for determining dr_mode and phy_type

2013-06-17T20:47:09Z

This adds two little devicetree helper functions for determining the dr_mode (host, peripheral, otg) and phy_type (utmi, ulpi,...) from the devicetree.

usb: phy: return -ENXIO when PHY layer isn't enabled

2013-03-18T09:18:26Z

in cases where PHY layer isn't enabled, we want to still return an error code (actually an error pointer) so that our users don't need to cope with either error pointer of NULL. This will simplify users as below: - return IS_ERR(phy) ? PTR_ERR(phy) : -ENODEV; + return PTR_ERR(phy); Acked-by: Kishon Vijay Abraham I Reported-by: Alan Stern Signed-off-by: Felipe Balbi

usb: phy: introduce ->set_vbus() method

2013-03-18T09:18:09Z

this method will be used to enable or disable the charge pump. Whenever we have DRD devices, we need to be able to turn VBUS on or off whenever we want. Note that in the ideal case, this would be controlled by the ID-pin Interrupt, but not all devices have ID-pin properly routed since manufacturers can choose to save that trace if they're building a host-only product out of a DRD IP. This is also useful during debugging where we might not have the proper cable hanging around. Signed-off-by: Felipe Balbi

usb: phy: make it a menuconfig

2013-03-18T09:18:05Z

We already have a considerable amount of USB PHY drivers, making it a menuconfig just prevents us from adding too much churn to USB's menuconfig. While at that, also select USB_OTG_UTILS from this new menuconfig just to keep backwards compatibility until we manage to remove that symbol. Signed-off-by: Felipe Balbi

usb: otg: add device tree support to otg library

2013-01-25T08:20:14Z

Added an API devm_usb_get_phy_by_phandle(), to get usb phy by passing a device node phandle value. This function will return a pointer to the phy on success, -EPROBE_DEFER if there is a device_node for the phandle, but the phy has not been added, or a ERR_PTR() otherwise.
