| * usb: phy: phy-generic: fix return value check in usb_nop_xceiv_register()Wei Yongjun2013-11-251-1/+2
| | | | | | | | | | | | | | | | | | In case of error, the function platform_device_register_simple() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR(). Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Felipe Balbi <balbi@ti.com>

| | | | | | | | | | | | | | | | | | | | | | Commit bd27fa44e13830d2baa278d5702e766380659cb3 (usb: phy: generic: Don't use regulator framework for RESET line) introduced regression: All users of usb_nop_xceiv_register() will fail because there is no platform data and the default reset GPIO is 0 which is a valid GPIO. Fix that. Signed-off-by: Aaro Koskinen <aaro.koskinen@iki.fi> Acked-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
| * usb: phy: generic: fix how we find out about our resourcesFelipe Balbi2013-11-251-31/+30Star
| | | | | | | | | | | | | | | | | | | | | | | | 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: remove dead codeMichal Nazarewicz2013-11-251-2/+0Star
| | | | | | | | | | | | | | | | | | | | | | Commit [4d175f34: usb: phy: nop: Defer clock prepare until PHY init] removed a goto reaching behind a “return ret” at the end of the function thus removing the only possible way that statement could be reached, and so rendering it a dead code. This commit cleans it up by removing said dead code. Signed-off-by: Michal Nazarewicz <mina86@mina86.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
* | usb: phy: initialize the notifier when add a new phyNeil Zhang2013-12-121-1/+0Star
|/ | | | | | | | | | We need to initialize the notifer before use it. So lets initialize it when add a new phy device to reduce the code redundancy. Signed-off-by: Neil Zhang <zhangwm@marvell.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
* usb: phy: generic: Don't use regulator framework for RESET lineRoger Quadros2013-10-041-28/+56
| | | | | | | | | | | | | | | 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 Brown2013-10-011-21/+3Star
| | | | | | | | | | 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 Siewior2013-08-091-58/+74
| | | | | | | | 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>

* usb: phy: rename nop_usb_xceiv => usb_phy_gen_xceivSebastian Andrzej Siewior2013-08-091-0/+292
The "nop" driver isn't a do-nothing-stub but supports a couple functions like clock on/off or is able to use a voltage regulator. This patch simply renames the driver to "generic" since it is easy possible to extend it by a simple function istead of writing a complete driver.
