[PATCH v2 0/3] usb: chipidea: msm: Clean and fix glue layer driver

[Ivan T. Ivanov]

From: "Ivan T. Ivanov" <iivanov-NEYub+7Iv8PQT0dZR+AlfA@public.gmane.org>

Hi, 

This series intend to fix driver, which was broken for a while. 
It is used to create peripheral role device, which in coordination
with phy-usb-msm driver will provide USB2.0 gadget support for
Qualcomm targets.

Changes since initial version.

 - Address comments from Peter - better description of the changes.
 - Drop patch 4 - till USB PHY driver is ready

Is this really the appropriate place to document this?  It seems like
this binding doc should be merged with the i.MX ci13xxx binding in a
common ci13xxx doc.

This driver is a "glue" layer driver which control Qualcomm 
specific logic around Chipidea IP core. It is supposed to 
hold "non standard" Chipidea properties, but I suppose that
ci-hdrc-qcom.txt will be better name and will be similar to 
i.MX chosen name.

    Did you send it to 'linux-usb'? I just didn't get the patch.
(Typically, the bindings are described in the same patch the DT support is 
added to the driver bu YMMV, of course.)

Although you mentioned to Josh that this is intended for "non-standard"
Chipidea properties, I don't see any other than requiring that 'dr_mode'
must be "peripheral".  It would seem that this should all be integrated
into a ci3xxx.txt.

Is there nothing more specific you could put here?  Maybe a hardware
revision, or something?

Although I would personally agree that this is the most logical method,
it would appear that the DT guys disagree with us [1].  Lately, they
seem to have either given up or are otherwise preoccupied, so perhaps
you can still slip a few patches by them. ;)

    Thank you for the reference.

    Yeah, I was at last able to get my Ethernet driver bindings applied. :-)

Re: [PATCH v2 0/3] usb: chipidea: msm: Clean and fix glue layer driver

[Tim Bird]

Ivan,

I'm having tremendous problems getting this driver to initialize.  For
some reason, I can't get the driver to actually transition the
hardware into peripheral mode.  At first I was getting a lot of probe
deferrals, based on not finding the regulators early enough in the
boot, and I thought it was an issue with the gadget drivers loading
before the driver could complete its setup.  However, I switched
everything to loading via modules, and now have less probe deferrals,
but I still can't get the driver to activate.  I see zero interrupts.
In particular the routine hw_device_state (which turns on interrupts
in the controller) is never called, because I can't get
msm_otg_start_peripheral to actually kick the hardware.

I've sprinkled the code in drivers/usb/chipidea and
drivers/usb/phy/phy-msm-usb.c liberally with printks and WARNs to help
me see what's going on, but I'm having a hard time tracing it down.
I'm pretty sure I've got the DTS correct, but my USB config might not
match yours.  (Would you mind sharing your config?).

I tried configuring the qcom,otg-control for user controlled mode
setting (via debugfs), and even with doing "echo "peripheral"
>/sys/kernel/debug/msm_otg/mode, it just wouldn't start the hardware
(call hw_device_state(...1)).

Any ideas you can provide would be welcome (e.g. for things to try,
look at, etc.)

My kernel is based on an internal Sony 3.13-rc6 kernel with clock and
regulator patches applied, as well as your phy-msm-usb.c patches from
November and your chipidea patches from yesterday.

Thanks,
 -- Tim

Re: [PATCH v2 0/3] usb: chipidea: msm: Clean and fix glue layer driver

Hi, 

I will need some time to recreate USB test
environment. I will come back when I am ready.

My understanding for gadget drivers is that you can have only one 
of them active in particular time. When compiled in kernel you can 
chose only one of them, also you can have only one module (function)
loaded. 


>   I see zero interrupts.

Right, I think that we will not see interrupts until we have
SPMI drivers which could control PMIC chip, PMIC is responsible
to do ID line detection and generate IRQ to APQ/MSM chip.

OTG state machine is not used at all. This phy-"otg" driver is 
working only in "peripheral" mode, because of missing PMIC
communication. 

The only callback which you could see to be executed is 
struct usb_otg::set_peripheral(), when you load gadget driver.

(Would you mind sharing your config?).

Sure. Attached.

Never testes this. It was there before.

You will need also 4th chipidea patch[1]. I have dropped it, because 
I will like to upstream PHY driver changes first. They are depended
anyway.

To reduce dependency to other drivers, I could recommend you to 
use Zero gadget driver. It should be enough to test USB stack, 
where APQ device will be peripheral and development workstation 
will be a host[2]. 


# cat zero.sh 
#!/bin/sh
cd /lib/modules/$(uname -r)/kernel/drivers/usb/gadget
insmod ./libcomposite.ko 
insmod ./usb_f_ss_lb.ko
insmod ./g_zero.ko

This is know non-fatal issue. I will try to see how to fix it.

Hm, there is no ci3xxx.txt. The closest match is ci-hdrc-imx.txt.
So it could be ci-hdrc-qcom.txt or my preferred name qcom,ci-hdrc.txt?

Opps, sorry. get_maintainer.pl did not list linux-usb and I forgot

Sorry, I was referring to ci13xxx-imx.txt, which was apparently moved to
ci-hdrc-imx.txt.  I was recommending to merge the two into one
'ci13xxx.txt', as this binding seems to be a new compatible for the same
basic chip.  Now perhaps 'ci-hdrc.txt'.

Although I agree with Josh that this name should be changed, and I think
either of your two suggestions would be acceptable, I would like to at
least discuss the possibility of actually merging the two in this
series.

Comments?

    I guess so, since the binding document would go in thru the USB tree 
anyway, IIUC.

usb_otg is not a good name for the node of usb phy.

Well, this is just an example. Is this better <&phy0>?

iMX version have required and recommender properties which are not 
meaningful for QCOM variant. I will prefer separate file. It depends 
on Freescale engineers (now in Cc:)

Unlike dwc3, there is no common dts entry for chipidea core, every platform
uses its own dts to cover both common and platform-specific properties.

I also have plan to use dwc3 style way for dts, but msm platform has still
not used dts, I don't know how many msm platforms need to change, once
you finish transferring msm to dts, I will split common and platform specific
entry.
