[PATCH v2 00/11] x86-android-tablets: convert to use GPIO references

[Dmitry Torokhov]

This series came about because now software nodes can be used to
describe GPIOs (via PROPERTY_ENTRY_GPIO() macros) and I would like to
eventually get rid of gpio_keys_platform_data structure.

So while I was doing the conversions from GPIO_LOOKUP() tables for
gpio_keys devices I decided to convert the rest of them as well. Maybe
some time in the future we can drop support for GPIO_LOOKUP() and rely
on device properties exclusively.

This is completely untested.

[PATCH v2 01/11] platform/x86: x86-android-tablets: convert Goodix devices to GPIO references

[Dmitry Torokhov]

Now that gpiolib supports software nodes to describe GPIOs, switch the
driver away from using GPIO lookup tables for Goodix touchscreens to
using PROPERTY_ENTRY_GPIO() to keep all touchscreen properties together.

Since the tablets are using either Baytrail or Cherryview GPIO
controllers x86_dev_info structure has been extended to carry gpiochip
type information so that the code can instantiate correct set of
software nodes representing the GPIO chip.

Because this adds a new point of failure in x86_android_tablet_probe(),
x86_android_tablet_remove() is rearranged to handle cases where battery
swnode has not been registered yet, and registering of GPIO lookup
tables is moved earlier as it can not fail.

[PATCH v2 04/11] platform/x86: x86-android-tablets: convert Novatek devices to GPIO references

[Dmitry Torokhov]

Now that gpiolib supports software nodes to describe GPIOs, switch the
driver away from using GPIO lookup tables for Novatek touchscreens to
using PROPERTY_ENTRY_GPIO() to keep all touchscreen properties together.

[PATCH v2 07/11] platform/x86: x86-android-tablets: convert wm1502 devices to GPIO references

[Dmitry Torokhov]

Now that gpiolib supports software nodes to describe GPIOs, switch the
driver away from using GPIO lookup tables for wm1502 devices to using
PROPERTY_ENTRY_GPIO().

Thanks this is an interesting series. I don't know why I missed / dropped
the ball on v1.

It will be a while before I can get around to this due to travel, but
I'll take a look and either provide a Tested-by or fixup any issues
I encounter and then post a fixed v3 myself.

Regards,

Hans

Thanks.

So I was curious and took a quick peek at the code, mainly at
the core changes.

I'm afraid that just setting the names here, and then
registering the node group below is not enough, see
the comment below.

As mentioned above just registering the node group here is not enough,
the nodes need to actually be assigned to the platform-devices which
are the parents of the GPIO controller, something like this from
a recent patch of mine which is not upstream yet:

static int __init acer_a1_840_init(struct device *dev)
{
        int ret;

        acer_a1_840_fg_dev = bus_find_device_by_name(&platform_bus_type, NULL, "chtdc_ti_batterry");
        if (!acer_a1_840_fg_dev)
                return dev_err_probe(dev, -EPROBE_DEFER, "getting chtdc_ti_battery dev\n");

        acer_a1_840_fg_node = fwnode_create_software_node(acer_a1_840_fg_props, NULL);
        if (IS_ERR(acer_a1_840_fg_node)) {
                ret = PTR_ERR(acer_a1_840_fg_node);
                goto err_put;
        }

        ret = device_add_software_node(acer_a1_840_fg_dev,
                                       to_software_node(acer_a1_840_fg_node));
        if (ret)
                goto err_put;

Except that this will only work if the GPIO controller gets probed()
after assigning the swnodes. Otherwise the GPIO controller itself will
not have the fwnode_handle inside struct gpio_chip set ...

Oh wait, that fwnode will already be set, it will point to the ACPI
fwnode. So setting the swnode on the platform device will likely work,
because that will be assigned to fwnode_handle->secondary and
the fwnode_handle pointer is shared between the platform-device
and the gpiochip, so adding the software_node to the platform-device
will also set fwnode_handle->secondary for the gpiochio (as it is
the same fwnode_handle).

So thinking more about it calling device_add_software_node() on
the GPIO controller parent platform-device doing something like\
the above should work ...

But only calling software_node_register_node_group() definitely
is not enough.

Hans

No, I'm afraid you misunderstand how software nodes for GPIOs work.

If you look into drivers/gpio/gpiolib-swnode.c, in particular at 
swnode_get_gpio_device(), is uses the name from the software node to
match with the name of registered gpiochip to locate it. The node itself
does not need to be attached to the gpiochip or it's parent device, it
is simply there to establish a link between GPIO reference
(SOFTWARE_NODE_REFEREMCE) and gpiochip structure.

So PROPERTY_ENTRY_GPIO is pretty much PROPERTY_ENTRY_REF which is:

#define PROPERTY_ENTRY_REF(_name_, _ref_, ...)				\
(struct property_entry) {						\
	.name = _name_,							\
	.length = sizeof(struct software_node_ref_args),		\
	.type = DEV_PROP_REF,						\
	{ .pointer = &SOFTWARE_NODE_REFERENCE(_ref_, ##__VA_ARGS__), },	\
}

and SOFTWARE_NODE_REFERENCE is

#define SOFTWARE_NODE_REFERENCE(_ref_, ...)			\
(const struct software_node_ref_args) {				\
	.node = _ref_,						\
	.nargs = COUNT_ARGS(__VA_ARGS__),			\
	.args = { __VA_ARGS__ },				\
}

swnode_find_gpio() scans these entries looking for the matching name,
and then resolves the references by taking the _ref_ software node,
using its name and doing:

	gdev = gpio_device_find_by_label(gdev_node->name);

Where gdev_node is that potentially unattached software node and name is
"INT33FC:00" or whatever.

It's actually on me: I sent it as you were reworking/adding more devices
to the driver and I was supposed to update the series but did not have
time.

Ack. I've already replied to the same remark in the
"[PATCH] platform/x86: barco-p50-gpio: use software nodes for gpio-leds/keys"
thread.

Lets continue discussing this there.

Thank you for this series. While reviewing this I've found
a couple of issues. I've fixed these in my own tree and
I'll send out a v3 with this fixed + some extra patches.

The issues which I've found and fixed are:

- lenovo_yoga_tab2_830_1050_init_codec() is missing a pinctrl_put()
  in error-exit paths after the pinctrl_get_select() succeeds

- Adding a swnode to the yt3 spi device changes the name of the SPI/codec
  device and the sound/soc/intel/boards/bytcr_wm5102.c machine driver looks
  up the code by name, update the machine driver to use the new name.

- In the "convert Yoga Tab2 fast charger to GPIO references" references
  the fwnode is added to the wrong device. The node should be added to
  the "serial0-0" device but that gets instantiated by
  drivers/platform/x86/lenovo/yoga-tab2-pro-1380-fastcharger.c
  I've made yoga-tab2-pro-1380-fastcharger.c propagate the fwnode set on
  the platform-device to the serdev it creates to fix this.

- Fix the commit message of "platform/x86: x86-android-tablets: convert
  gpio_keys devices to GPIO references" which contained a stray reference
  to wm5102.

I've also added some follow-up patches with some cleanups, see the v3
cover-letter for details.

I'll also add a rebased version of my patches to add support for
the Acer A1-840 tablet to v3, now using software-nodes for the GPIOs.

Regards,

Hans

Thank you Hans for looking over the series and fixing up all the issues
that I introduced.

I've reviewed ones that I felt comfortable reviewing, thanks again.

You're welcome and thank you for the reviews on the new patches.
