* usb: phy: generic: add vbus supportRobert Jarzmik2015-01-121-0/+6
| | | | | | | | | | | | Add support for vbus detection and power supply. This code is more or less stolen from phy-gpio-vbus-usb.c, and aims at providing a detection mechanism for VBus (ie. usb cable plug) based on a GPIO line, and a power supply activation which draws current from the VBus.

* usb: phy: generic: migrate to gpio_descRobert Jarzmik2015-01-121-2/+2
| | | | | | | | | | | | | | | Change internal gpio handling from integer gpios into gpio descriptors. This change only addresses the internal API and device-tree/ACPI, while the legacy platform data remains integer space based. This change is only build compile tested, and very prone to error. I leave this comment for now in the commit message so that this patch gets some testing as I'm pretty sure it's buggy.

* usb: phy: rename <linux/usb/usb_phy_gen_xceiv.h> to ↵Felipe Balbi2014-04-211-1/+1
| | | | | | | | | | <linux/usb/usb_phy_generic.h> now that all functions match the driver name, the only missing piece is to rename the header file itself. Signed-off-by: Felipe Balbi <balbi@ti.com>
* usb: phy: rename usb_nop_xceiv to usb_phy_genericFelipe Balbi2014-04-211-3/+3
| | | | | | | | no functional changes, just renaming the function in order to make it slightly clearer what it should be used for, also matching the driver name. Signed-off-by: Felipe Balbi <balbi@ti.com>
* usb: phy: generic: fix how we find out about our resourcesFelipe Balbi2013-11-251-1/+3
| | | | | | | | | | | | instead of having each user of generic phy find out about its own resources and pass it to the core layer, have th core layer itself figure that out. It's as simple as moving a piece of code around. This fixes a big regression caused during the merge window where am335x-based platforms wouldn't be able to probe their PHY driver.

* usb: phy: generic: Don't use regulator framework for RESET lineRoger Quadros2013-10-041-3/+3
| | | | | | | | | | | | | | | Modelling the RESET line as a regulator supply wasn't a good idea as it kind of abuses the regulator framework and also makes adaptation code more complex. Instead, manage the RESET gpio line directly in the driver. Update the device tree binding information. This also makes us easy to migrate to a dedicated GPIO RESET controller whenever it becomes available. Signed-off-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
* usb: phy: nop: Defer clock prepare until PHY initMark Brown2013-10-011-1/+0
| | | | | | | | | | Since we only enable the PHY clock on init and the PHY init and shutdown does not occur in atomitc context there is no need to prepare the clock before it is enabled. Move the clk_prepare() operations to go along with the enables, allowing the clock to be fully idle when not in use.

* usb: phy: phy-generic: export init functionsSebastian Andrzej Siewior2013-08-091-0/+20
This patch exports the mostly generic functions so they can be used from other phy driver instead of duplicating the code. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Felipe Balbi <balbi@ti.com>
