usb: phy: move all PHY drivers to drivers/usb/phy/

2013-03-18T09:18:04+00:00

that's a much more reasonable location for
those drivers. It helps us saving drivers/usb/otg/
for when we actually start adding generic OTG
code.

Also completely delete drivers/usb/otg/ as there's
nothing left there.

usb: otg: move usb_otg_state_string to usb-common.c

2013-03-18T09:18:03+00:00

otg.c only had a single function definition
which might make more sense to be placed in
usb-common.c. While doing that, we also delete
otg.c since it's now empty.

usb: otg: prefix otg_state_string with usb_

2013-03-18T09:18:03+00:00

all other functions under drivers/usb/ start
with usb_, let's do the same thing.

This patch is in preparation for moving otg_state_string
to usb-common.c and deleting otg.c completely.

kfree on NULL pointer is a no-op.

usb: phy: mxs: use readl(), writel() instead of the _relaxed() versions

2013-03-18T09:17:59+00:00

This patch converts the mxs-phy driver from readl_relaxed(), writel_relaxed()
to the plain readl(), writel() functions, which are available on all platforms.

This is done to enable compile time testing on non ARM platforms.

usb: phy: mxs-phy: register phy with framework

2013-03-18T09:17:59+00:00

We now have usb_add_phy_dev(), so use it to register with the framework
to be able to find the phy from the USB driver.

usb: phy: move bulk of otg/otg.c to phy/phy.c

2013-03-18T09:17:58+00:00

Most of otg/otg.c is not otg specific, but phy specific, so move it
to the phy directory.

USB: phy: nop: Defer probe if device needs VCC/RESET

2013-03-18T09:15:18+00:00

Add 2 flags, needs_vcc and needs_reset to platform data.
If the flag is set and the regulator couldn't be found
then we bail out with -EPROBE_DEFER.

For device tree boot we depend on presensce of vcc-supply/
reset-supply properties to decide if we should bail out
with -EPROBE_DEFER or just continue in case the regulator
can't be found.

This is required for proper functionality in cases where the
regulator is needed but is probed later than the PHY device.

can now be provided via device tree.

usb: phy: nop: use new PHY API to register PHY

2013-03-18T09:15:02+00:00

We would need to support multiple PHYs of the same type
so use the new PHY API usb_add_phy_dev() to register the PHY.
