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: generic: fix how we find out about our resources 2013-11-25T16:25:57+00:00 Felipe Balbi balbi@ti.com 2013-10-24T14:45:29+00:00 af9f51c5512f9d55972603dd5dd90d0fa300b200 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.

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>

Move the clk_prepare() operations to go along with the enables, allowing the clock to be fully idle when not in use.
