[PATCH 00/20] ARM: dts: Add USB and OTG related nodes and enable on various boards

[Hans de Goede]

Hi Maxime,

Here is a patch-set with all the otg / sun8i-usb-host related dts patches
I've accumulated.

These are intended for 4.3, and go hand in hand with the outstanding
musb-sunxi / phy-sun4i-usb patches, which I expect to be merged as is
for 4.3 .

Regards,

Hans

[PATCH 07/20] ARM: dts: sun8i: Add support for USB controllers on A23/A33

[Hans de Goede]

From: Chen-Yu Tsai <wens-jdAy2FN1RRM@public.gmane.org>

A23/A33 has one pair of EHCI/OHCI USB controllers. There are 2 USB PHYs,
one for the USB OTG controller, one for the EHCI/OHCI pair. The latter
may also support HSIC, though none of the available boards utilize this,
so this is not supported yet.

[PATCH 07/20] ARM: dts: sun8i: Add support for USB controllers on A23/A33

[Hans de Goede]

From: Chen-Yu Tsai <wens@csie.org>

A23/A33 has one pair of EHCI/OHCI USB controllers. There are 2 USB PHYs,
one for the USB OTG controller, one for the EHCI/OHCI pair. The latter
may also support HSIC, though none of the available boards utilize this,
so this is not supported yet.

[PATCH 15/20] ARM: dts: sun7i: Enable USB DRC on Bananapi (BROKEN!)

[Hans de Goede]

Enable the otg/drc usb controller on the Bananapi.

This is based on the fex file settings which claim that vbus-det is
PH5, but this does not work and the schematic shows that it is actually
connected to gpio1 of the axp209, so we cannot add otg support for the
bananapi until we get support for the axp209 gpio pins in the kernel.

[Hans de Goede]

Enable the otg controller on Ippo Q8H tablets, for now it is enabled
in host-only mode, because true OTG support requires support for
detecting and enabling Vbus through the axp221 pmic.

For this to work the Vbus on the port must be enabled by u-boot,
or a powered hub must be used.

[PATCH 17/20] ARM: dts: sun8i: Enable USB DRC on Ippo Q8H-A33 tablet

[Hans de Goede]

Enable the otg/drc usb controller on the Ippo Q8H-A33 tablet, for now it
is enabled in host-only mode, because true OTG support requires support
for detecting and enabling Vbus through the axp221 pmic.

For this to work the Vbus on the port must be enabled by u-boot,
or a powered hub must be used.

I'm fine with these patches. Do you have a branch somewhere that I can
pull (without the one that you wanted me to drop, obviously)?

Are these before the conversion to DT label syntax or after (meaning
that the conversion patches got pulled somewhere already)?

Thanks

Yes. They've been in my tree for a few monthes now, and have been in
linux-next and arm-soc for quite some time too.

I've just created a branch with just these patches directly on top
of sunxi/for-next for you:

https://github.com/jwrdegoede/linux-sunxi/commits/otg-dts-for-maxime

While preparing this branch I noticed that the dts for
the ippo q8h a33 tablets is not yet merged:

http://www.spinics.net/lists/devicetree/msg82149.html

You suggested to use the DT quirks interface instead of creating
a separate dts for each board variant, and in the end I agreed,
and asked you to merge it renamed to a more generic name
without the lcd1024x600 bit in there.

I can make it more generic and resend it myself. Do you want me
to squash in the otg changes when I resend it, or shall I keep
those separate ?

Regards,

Hans

Please ignore this for now. There have been some changes to the extcon
framework, making it more integrated with devicetree, this means I need
to add an extcon property to the musb nodes in devicetree:

Sorry for being so late on that, let's discuss this in the other
thread.

Just to make things clear, it's the updated version with extcon that I

Does that work? 

Your phy driver seem to actively check at probe time for both the ID
detect and VBUS detect pins to be set in the DT, which is not the case
here.

I don't really get either why VBUS detect has to be set. Can't it work
just fine if you have a regulator that you can control and the ID pin
alone ?

Yes :)

My initial version did, later on I added a patch adding special handling
for boards which have Vusb hardwired to the 5V of the board such as the
cubieboard (the schematics show both a current regulator and an optional
0 ohm resistor to short-circuit that, it seems that the boards are
shipped with short-circuiting resistor, at least all mine are (both a10
and a20 variants).

See here for the patch:
https://github.com/jwrdegoede/linux-sunxi/commit/b73922986cab2bad9d54a2a1223583008e155bc4

This is part of the v5 phy-sun4i-usb series I send to Kishon a week ago.

Not really, we can work around it as done in the above commit, but it
is not ideal.

Vbus detect going low is used by the musb silicon to determine that the
current session has ended, and without this happening it will not
switch from host to device mode or vice versa no matter what the id pin
does.

Vbus detect is also used to not provide power to the port if external
power is present as doing so is not a good idea.

Last vbus-detect is used to detect that the devices connected to the
port are using too much power.

Hans
