[Patch v5 08/13] ARM: imx6q: add config-on-boot gpios

[Richard Zhao]

Sometimes, boards have gpios that don't own by any driver or owner
by a generic driver that don't like hacks. Such gpios is normally
output and need setup once on boot. So I introduce the config-on-boot
gpios.

+* Configure on Boot
+
+Node name: config-on-boot
+  It must be in root node. config-on-boot means to describe settings that needs
+  to be set one time on boot but aren't owned by any driver, or the owned driver
+  is too generic to handle such settings. For example, usb hub uses generic
+  driver in usb core code, a on-board usb may need deassert reset pin.
+
+Optional properties:
+- output-gpios: Output gpio array that needs to set.
+- output-gpio-values: This property is required if output-gpios is set.
+  The value is a array of 0 or 1. Total count eaquals the number of gpios.

Sometimes, boards have gpios that don't own by any driver or owner
by a generic driver that don't like hacks. Such gpios is normally
output and need setup once on boot. So I introduce the config-on-boot
gpios.

+* Configure on Boot
+
+Node name: config-on-boot
+  It must be in root node. config-on-boot means to describe settings that needs
+  to be set one time on boot but aren't owned by any driver, or the owned driver
+  is too generic to handle such settings. For example, usb hub uses generic
+  driver in usb core code, a on-board usb may need deassert reset pin.
+
+Optional properties:
+- output-gpios: Output gpio array that needs to set.
+- output-gpio-values: This property is required if output-gpios is set.
+  The value is a array of 0 or 1. Total count eaquals the number of gpios.

NAK. This is not a h/w description and should be solved within the
kernel or bootloader. Either fix this in u-boot, the platform code, or
make the generic driver support this in a generic way.

Yes, it should be here. But then, it's some usb reset, so maybe the PHY should

Well, this is platform specific stuff, so it shouldn't be in any way part of the 
driver.

It's called just after populate devices. It's hard for generic driver to
decide when it's called.

And we don't want to polute uboot either, so this is a good move.

Write a driver that does the GPIO setup in some generic way? Wasn't there 
something about this stuff going on? Shawn, you had some comments /wrt the M28 
DTS. This might be what you meant?

Just listing possible options. Obviously, no one wants the dirty stuff
in their code...

There would never be a need in u-boot to support boot from USB mass
storage? In which case you would have to handle this reset line leaving
it deasserted and linux would likely never know. (Yes, I know we can't
rely on bootloader setup.)

An embedded hub with gpio controlled reset line sounds fairly generic to
me. The only platform specific part is which gpio line which is nothing
new to deal with.

On the other hand, this is really a flaw in the h/w design as whether
the hub is integrated on board or a separate hub should be transparent
to s/w. So just keeping it contained in platform code may be the best
option.

You are defining something based on whether linux has a driver or not.

You need to describe that you have a hub on the usb bus and add the gpio
line to that node. Just like PCI is probe-able, you still need DT nodes
sometimes for cases like this. A simpler approach would be to just add
the gpio to the ehci controller node, but that's not exactly correct.

We already support that obviously ;-)

But we defer the initialization of USB to a point where user really needs it. 
Therefore if you boot from ie. NAND, you won't have the USB inited anyway.

And what about embedded hub that has two distinct power GPIOs? And we can go 
forever with this discussion.

I don't think so. You might want to minimize the power consumption by disabling 
the hub power completely.

We already support that obviously ;-)

But we defer the initialization of USB to a point where user really needs it. 
Therefore if you boot from ie. NAND, you won't have the USB inited anyway.

And what about embedded hub that has two distinct power GPIOs? And we can go 
forever with this discussion.

I don't think so. You might want to minimize the power consumption by disabling 
the hub power completely.

This is okay, but it's more common to test for root hubs with

This message is rather useless. It is really not expected for kzalloc
to fail. If it fails here you really have problems elsewhere and this
message won't help you debugging it.

Is stmp_reset_block() suitable for what you want to do here?

Please add the return value to these kind of messages.

This message is rather useless. It is really not expected for kzalloc
to fail. If it fails here you really have problems elsewhere and this
message won't help you debugging it.

The i.MX27 also has this core. As it's older that's probably the right
fallback instead of i.MX31.

If you have braces in one path of a if/else add them to the other path
aswell.

Could you recheck with your hardware guys which input clocks
this device really has. On earlier i.MX there are up to three
clocks this module needs. Sooner or later we want to use this driver on
the other i.MX aswell, and then we'll need support for the other clocks
here, no matter if they are software controllable on i.MX6 or not.

It's not useless, but it'll hardly ever be displayed if you run out of memory so 
badly this kzalloc() will fail.

If you run out of memory while allocating a few bytes it's really
not interesting where exactly this happens. The message won't give
you any hint where you can fix this problem. Also, if you bail out
of a drivers probe function with -ENOMEM you will have a message
in the log anyway.

Yes, the device needs this, but afaik the of platform code will set this
for you. You only have to do this manually for devices which you
allocate yourself.

Only two clocks are needed for i.mx6, one is AHB clock usb gate which
is used to visit registers, and other is PHY clock which is used to data transfer.

The i.mx23, i.mx28 and i.mx6q use FSL Internal PHY, it doesn't need serial clock.

So it will be like:
if (unlikely(hcd->phy && !hdev->parent)) {

And,
I didn't check (portchange & USB_PORT_STAT_C_CONNECTION), because if
the device is connected on boot, there'll be no USB_PORT_STAT_C_CONNECTION.
Is it acceptable?

Unfortunately, devices device tree populated don't set dma_mask.
It always hit if (!pdev->dev.dma_mask). I'm not the only one suffer it.

I just define the board needs some misc settings. If you think

PCI has dev id and may add quirks. But for embedded, I don't know how
to connect a of node to a hub device enumerated by usb core code. And
it may also pollute the usb core code.

Some phy maybe passed by usb_set_transceiver. It's handled by chipidea
udc driver.

Same reason as above. We still have chance to pass phy
by usb_set_transceiver.

Yes.  In fact the hub_port_debounce() routine turns off
USB_PORT_STAT_C_CONNECTION anyway.

No.  What Richard is looking for is a way to set/clear gpio, while
what I was commenting on M28 DTS is the way to configure a pin into
gpio mode.  In this series, Richard chose to use "hog" feature to
configure the pin into gpio mode, which means defining a pinctrl state
for pin controller node itself, then at pinctrl subsystem init time,
pinctrl core will configure these "hog" pins properly.

The "hog" method makes some sense for Richard's case, where the pin
has no clear device/driver owner, and when gpio_request call can not
configure the requested pin into gpio mode automatically yet.

I am trying your patch series on a mx28evk and I am not able to have
my USB pen drive detected.

I tried enabling all the required config options in .config.

Could you please share your .config?

Do you have root TT enabled? If the pendrive isn't detected at all, it's 
probably the PHY not enabling (disabling?) the discon detector upon init. But 
the PHY driver is from my code, so that should work. Do you see any response at 
all upon connecting the stick?

So what is the magic needed here? Isn't Richard's series supposed to work as is?

What should be done in addition to Richard's patch in order to get USB
host to work on mx28evk?

Ah right, you need to toggle the power supply (vbus) GPIO.

Toggle it where?

I see the following:

reg_usb0_vbus: usb0_vbus {
compatible = "regulator-fixed";
regulator-name = "usb0_vbus";
regulator-min-microvolt = <5000000>;
regulator-max-microvolt = <5000000>;
gpio = <&gpio3 9 0>;
enable-active-high;

So the gpio3_9 will turn on the vbus.

What is missing?

Please check my config file again:

It does have:

CONFIG_USB_CHIPIDEA=y
CONFIG_USB_CHIPIDEA_HOST=y

Can someone confirm that this patch series works on a mx28evk? If it
does, please send me the .config that works.

Thanks,

Couldn't this function be made generic and put outside of mach-imx6q.c
so that other platforms could use it?

I need the same for mxs.

I would like to use this same concept on mxs, which does not have a
"iomuxc" driver like imx6.

To which driver should I glue the 'pinctrl-0 = <&pinctrl_gpio_hog>;'  on mxs?

Yes, it is common. But it must be called after populate devices.  Rob didn't agree the way yet.

USB also uses device and manufacturer ids. One of the main reasons for
putting pci devices into dts is to describe out of band signals just
like this.

Creating a binding and support code for full usb bus topology would be a
lot of work which is why I propose a simpler approach below.

I mean just something like "fsl,hub-reset-gpios" in the ehci device
node. It's at least under a usb node. Whether the ehci driver handles
this or you just have a separate piece of code to find this property and
setup the gpio is up to you.

I ever had an argument on this.  If we have "fsl,hub-reset-gpios"
defined in ehci device node, it should simply be ehci driver who needs
to find this property and set up the gpio.  Defining the property in
ehci device node while having platform code to find the property just
seems wired to me.  That said, if it's not ehci driver who will use
the property, we should not define the property in in ehci device node.

I haven't been following the thread, but just noticed it. Very similar
things (DT nodes for probed devices) are coming up quite a bit recently,
for example:

Re: Where to power on the wifi device before loading the driver.
http://www.spinics.net/lists/arm-kernel/msg180368.html

dt: rfkill-gpio: add bindings documentation
http://www.spinics.net/lists/linux-tegra/msg03977.html

I wonder if there's any kind of infra-structure or standardized bindings
that would be useful here?

I haven't been following the thread, but just noticed it. Very similar
things (DT nodes for probed devices) are coming up quite a bit recently,
for example:

Re: Where to power on the wifi device before loading the driver.
http://www.spinics.net/lists/arm-kernel/msg180368.html

dt: rfkill-gpio: add bindings documentation
http://www.spinics.net/lists/linux-tegra/msg03977.html

I wonder if there's any kind of infra-structure or standardized bindings
that would be useful here?

Hi Stephen,
For your suggestion: 

sdhci@78000000 {
	compatible = "nvidia,tegra30-sdhci", "nvidia,tegra20-sdhci";
	reg = <0x78000000 0x200>;
	interrupts = <0 14 0x04>;

	sdio-device {
		reset-gpios = <...>;
		enable-gpios = <...>;
	};
};

I have a question, if reset-gpio or enable-gpio is not set, how bus (sd or usb) know
it is a sdio device as the wifi is not powered on at the time, it will not response host's
command,  the hub at usb bus is the same.

There's no requirement that 1 DT node be 1 driver. That's purely an OS
decision and it's usually simpler that way. But if it it's just a one
time thing at boot, then its fine for the platform code to handle it.

That's a good point. We need those properties to be part of the device
that controls the port/slot/connector, not the thing that plugs into it.
Having each such binding and driver implement this themselves might not
be a good idea though. Perhaps we can standardize on a mechanism for
this; something vaguely like rfkill, but for arbitrary types of devices
connected to ports.

For USB at least, where the power/reset/... GPIOs might affect just one
port on a hub rather than the root USB host controller, the issue of
representing these properties on a dynamically probed device still
applies. Something like:

ehci {
    /* The following node is dynamically detected, although the hub
     * IC is physically soldered onto the board
     */
    hub {
        hub { /* also dynamic */
            port@2 {
                child-supply = <&regulator>;
                reset-gpios = <&gpio 0 0>;
            };
        };
    };
};

But without knowing what might be connected to port@2, how do we know
how to sequence the power supply and reset GPIOs according to its
requirements? I guess this is part of the specification of the port
itself though, not the attached device, since anything that is allowed
to plug in must conform to whatever sequencing the port is designed to
give. If the connected device is known, the port@2 node in DT can encode
whatever sequencing requirements are associated with the known connected
device.

In fact, for specific usb/sdio interface device, there should be a specific interface 
class driver for it, the best place is at that class driver, like wifi or 3g driver,
as it is chip/device specific.

But the generic 3G and HUB devices are special, there is only one common driver
for each of them (drivers/usb/core/hub.c & drivers/serial/option.c)

But like you said, there's no way to tell what's attached to a USB or
SDIO port before probing it, at least if the port is at all
user-accessible. The class driver for the host-side of the port (USB hub
or SDIO controller) would be the one that needs to implement this, not
the class driver for the thing that could be plugged in (WiFi or 3G device).

But like you said, there's no way to tell what's attached to a USB or
SDIO port before probing it, at least if the port is at all
user-accessible. The class driver for the host-side of the port (USB hub
or SDIO controller) would be the one that needs to implement this, not
the class driver for the thing that could be plugged in (WiFi or 3G device).

Agree, I did not consider the situation that the class driver is loaded as 
module and only be loaded when that kinds of device (wifi/3g) has found
(through udev).

Maybe we have to add misc control (power/reset) for devices at sd or usb 
controller driver's probe, and those gpio are belonged to controller's.

While trying to use this code: Is there a special reason why all pins 
are set to HIGH here? The contents of 'output-gpio-values' seem to be

It may be bug here. The patch is rejected. imx6_sabrelite happens work
by default value. So I won't follow it any more.
