Based on 'u-boot-usb' master branch.
This patch-series includes majorly some clean-up, few fixes and
then some basic super-speed usb infrastructure addition, to help
put support for XHCI in near future.
Changes from v2:
- Added a patch "usb: common: Weed out USB_**_PRINTFs from usb framework"
to replace USB_***_PRINTF with debug() so as to get rid of unnecessary
DEBUG macros in usb common framework and thereby rebasing other patches
on top of this so that no USB_PRINTF appears further.
- Added a patch to reset only USB 2.0 ports, since USB 3.0 protocol ports
don't require a reset to happen to move to 'enabled' state.
- Added a patch to move definition of 'min3()' out of ehci-hcd and putting
the same as macro definition in common header.
- Using a 'switch-case' in portspeed() in cmd_usb.c
Changes from v1:
- Fixing the issue with 'ifno' as well as added 'if_desc'.
- Instead of turning-on only powered-off hub ports, power-cycle all
the hub ports (aka: turning off and then turning on again power to
all the ports.
- Fixing commenting style problem in
'usb: Update device class in usb device's descriptor'
- Fixing typo in commit message for
'usb: hub: Fix enumration timeout'
- Removing separate definition for 'struct usb_ep_desc'; thereby adding
'struct usb_ss_ep_comp_descriptor' to 'struct usb_interface' only.
As a result modifying the patch accordingly also dropping the patch
'usb: eth: Fix for updated usb interface descriptor structure'
- Dropping the patch 'usb: hub: Increase device enumeration timeout for broken
drives' for now (will come back with a solution at later point of time).

USB_PRINTF, USB_HUB_PRINTF, USB_STOR_PRINTF, USB_KBD_PRINTF
are nothing but conditional debug prints, depending on DEBUG.
So better remove them and use debug() simply.

Patch b6d7852c increases timeout for enumeration, taking
worst case to be 10 sec.
get_timer() api returns timestamp in milliseconds, which is
what we are checking in the do-while() loop in usb_hub_configure()
(get_timer(start) < CONFIG_SYS_HZ * 10).
This should give us a required check for 10 seconds, and thereby
we don't need to add additional mdelay of 100 microseconds in
each cycle.

This adds usb framework support for super-speed usb, which will
further facilitate to add stack support for xHCI.

As per XHCI specifications USB 3.0 protocol ports attempt
to advance to 'Enabled' state; however USB 2.0 protocol ports
require software reset to advance them to 'Enabled' state.
Thereby, inferring that software need to reset USB 2.0 protocol
ports invariably (as per EHCI spec or xHCI spec).

We can use a common global macro for calculating minimum of
3 numbers. Put the same in 'common header' and let 'ehci'
use it.

You might want to keep it as an inline-function to allow GCC do the type-

I actually checked now just for omap3_evm configuration by trying out:
make distclean
make omap3_evm_config
make
But strangely i didn't get any build errros for omap3_evm board on
explicitly compiling for it.
Any clue ?

there.

We can use a common global method for calculating minimum of
3 numbers. Put the same in 'common header' and let 'ehci'
use it.

It doesn't make sense to use the USB_PORT_FEAT_ constants to read a port status
here. These should be USB_PORT_STAT_ instead (you could use a switch statement
if you mask and shift them correctly).

Speed is never set as a feature anyway. We should just get rid of all of these
and always use USB_PORT_STAT_ for them.

These two new values are *not* correct. 0x800 is actually PORT_TEST, and 0x1000
is PORT_INDICATOR. Full speed has always been reported by having both the
LOW_SPEED and the HIGH_SPEED bits zero, and you should define it that way (for
use in switch statements).
If you want to fake SuperSpeed into the USB 2.0 hub descriptor (see my comment
on xhci_port_speed in the unreleased CL), you could represent it with 0xc00,
which should be a reserved value for all existing 1.0 and 2.0 hubs.

Maybe this should be renamed to USB_PORT_STAT_SPEED_MASK to make its purpose
clearer.

I would reword "Additions" to "Changes" and explicitly state that these fields
concern the new USB 3.0 hub descriptor format, which is different and

For consistency, I would prefix all values in here with USB_SS_PORT_STAT_ (to

There is nothing wrong with this, but I also don't think you need it. In those
places where you check for the hub class in your XHCI stack, you actually want
to check whether the device is the root hub... so you should do that
differently to avoid breaking external hubs (e.g. by comparing the device
address). I think we should drop this since there is no real use for it.

This adds 20ms per port to USB boot times... is it really necessary? Why do we
need to powercycle XHCI ports? Couldn't we just check if the ports are powered
and only power them on if they aren't?
If you insist, please at least parallelize this. Disable power on all ports,
wait, then check and reenable it.

This is a severe error (because the ports won't come up again), so I think it

They're not in, but they're already pushed in my tree. It'd be also easier to
review diff instead of full patches again.

True, we should be 'ANDing' here with respectve PORT_STAT_ constants,

These are simply 'Hub class feature numbers' given in USB 2.0 and 3.0 specs.
Why don't we just keep them like that (I shall be removing the
USB_PORT_FEAT_FULLSPEED
and USB_PORT_FEAT_SUPERSPEED definitely from here). In case we want to
check the port status field,
we would check against PORT_STAT_ constants.

This bit fields are actually additions to USB 3.0 framework. These
fields are not defined in
USB 2.0 specs, or else they are reserved there. If you insist i can

I shall send a diff patchset for these changes, but do we have a
possibility of squashing the changes
to earler commits at some point of time later, so that clean changes
get to u-boot ?
Or we shall go as you suggest.

This 20ms delay is truely being taken to be on safer side (twice of
Power-on-to-power-good),
its not observational.
In my earlier patch-series, we were doing the same way as you are
suggesting here (power-on
ports only if they aren't), however Marek suggested to power-cycle the
ports. This would ensure
that we don't have any spurious Port status (telling us that port is
powered up).
Actually i was seeing a strage behavior on USB 2.0 protocol ports
available with XHCI.
Since all ports with XHCI are powered-up after a Chip-reset, the
instant we do a power-on
on these ports (as with original code - simply setting the PORT_POWER
feature), the Connect status
change bit used to get cleared (however Current connect status bit was
still set).
So we arrived at solution that either we don't power-up XHCI ports or
do a power-cycle on them.

Hmm, so right now we are doing this for one port at a time.
I am sure parallelising things as you suggested would be best to do here, but
can you please explain, would handling one port at a time lead to unwanted
behavior from Host's side somehow ?

NAK, sorry. Lets re-sync with the kernel's min/max/min3/max3 defines

Fair enough... I guess 20ms overall is not a big deal in the whole
picture. I sometimes tend to overoptimize things...

This is a bug in your XHCI code I hadn't spotted before: in
xhci_submit_root(SET_FEATURE) you read the PORTSC register, add a bit,
and write it again... without calling xhci_port_state_to_neutral()
inbetween. Thus you clear any pending change events when you set
PORT_POWER. (Seems the EHCI code has a similar bug in CLEAR_FEATURE,
now that I'm looking at it... someone should put a 'reg &=
~EHCI_PS_CLEAR;' in there.)

It doesn't affect correctness, just the amount of time "wasted". Doing
it one port at a time means you wait 100ms on a 5 port root hub, while
you could get by with 20ms overall by parallelizing it.

Yes, okay, I think we mean the same thing here. I just wanted to point
out that the USB 3.0 port status is actually a completely different
thing from the USB 2.0 port status (which is still valid for
non-SuperSpeed hubs in USB 3.0 environments, even though the spec
hasn't printed it out again). They did not just *add* a few bits to
the old status bit field, they actually *changed* existing bits (not
just reserved ones)... e.g. bit 9 means LOW_SPEED for USB 2.0 hubs but
PORT_POWER for SuperSpeed hubs. I found this very confusing when I
first read it, so I thought it might be worth making it extra obvious
through comments.

Right, we need to do that.

True, EHCI has it for SET_FEATURE but not for CLEAR_FEATURE.

True, will amend this as required.

Sorry, forgot this one yesterday. I would consider to just drop/revert
this patch entirely. It's not wrong, but it adds complexity where it is
not needed. You don't have to reset SuperSpeed devices, but it shouldn't
hurt either and from what I can tell Linux does it as well.

Alright, we will drop this.
I think a possible bug related to calling xhci_port_state_to_neutral()
in xhci_submit_root()
(one pointed by Julius in [PATCH v3 3/8] usb: hub: Power-cycle on
root-hub ports) was causing
USB 3.0 protocol ports fail while resetting.
Now things are fine.

We need to drop this from u-boot-usb/next branch, right ?
I am sure this is added to you to-do list, just wanted to make sure
since i could
see it in 'next' right now.
