usb: phy: am335x-control: wait 1ms after power-up transitions

2014-04-21T15:21:24+00:00

Tests have shown that when a power-up transition is followed by other
PHY operations too quickly, the USB port appears dead. Waiting 1ms fixes
this problem.

usb: phy: am335x-control: include appropriate header file in phy-am335x-control.c

2013-12-19T15:27:42+00:00

Include header file drivers/usb/phy/am35x-phy-control.h in
phy/phy-am335x-control.c because function am335x_get_phy_control() has
its prototype declaration in drivers/usb/phy/am35x-phy-control.h.

Also, remove definition of structure phy_control because it is already
defined in the included header.

This eliminates the following warning in phy/phy-am335x-control.c:
drivers/usb/phy/phy-am335x-control.c:114:21: warning: no previous prototype for ‘am335x_get_phy_control’ [-Wmissing-prototypes]

usb: phy: am335x-control: Remove redundant of_match_ptr

2013-10-01T14:56:24+00:00

The data structure of_match_ptr() protects is always compiled in.
Hence of_match_ptr() is not needed.

usb: phy: am335x: add wakeup support

2013-10-01T14:31:11+00:00

This is based on George Cherian's patch which added power & wakeup
support to am335x and does no longer apply since I took some if the code
apart in favor of the multi instance support.
This compiles and I boots and later it detects a device after I plug it in :)
Could somebody please test it so it does what it should?

usb: phy: am335x-control: make it compile with

Randy reported this
|drivers/usb/phy/phy-am335x-control.c:45:3: error: implicit declaration
|of function '__WARN' [-Werror=implicit-function-declaration]

and left it as an excercice to figure out that this happens only with
CONFIG_BUG=n. As a fix I replace it with WARN_ON(). And there is a space
before return so fix this, too.

usb: phy: am335x: include linux/err.h

2013-08-13T19:59:13+00:00

Stephen Rothwell reported that this driver does not compile on PowerPC
due to this missing include. One could argue why this driver is enabled
on PowerPC in the first place but it sure isn't wrong to include headers
for used function instead of to rely that they sneak in.

usb: phy: Add AM335x PHY driver

2013-08-09T14:34:15+00:00

This driver is a redo of my earlier attempt. It uses parts of the
generic PHY driver and uses the new control driver for the register
the phy needs to power on/off the phy. It also enables easy access for
the wakeup register which is not yet implemented.
The difference between the omap attempt is:
- no static holding variable
- one global visible function which exports a struct with callbacks to
  access the "control" registers.
