The GPIO_DEVICE symbol belonged to a custom driver that was removed from

Even though TRACEPOINTS is not enabled in my kernel config, my build

OpenWrt's special gpio-button-hotplug driver is still using
exclusively the legacy GPIO Subsystem gpio_ API.
While it still does work fine for most devices, upstream
linux is starting to convert platform support like that of
the APU2/3/4 to the new GPIOD LOOKUP tables that are not
supported by it.
Hence, this patch replaces the gpio_ calls present in
gpio-button-hotplug with gpiod_ equivalent wherever
it's possible. This allows the driver to use the
gpiod lookup tables and still have a fallback for
legacy platform data code that just sets button->gpio
set to the real button/switch GPIO.
As a bonus: the active_low logic is now being handled
by the linux's gpio subsystem too. Another issue that
was address is the of_handle leak in the dt parser
error path.

This patch unifies the polled and interrupt-driven gpio_keys code
paths as well implements consistent handling of the debounce
interval set for the GPIO buttons and switches.
Hotplug events will only be fired if
1. The input changes its state and remains stable for the duration
of the debounce interval (default is 5 ms).
2. In the initial stable (no state-change for duration of the
debounce interval) state once the driver module gets loaded.
Switch type inputs will always report their stable state.
Unpressed buttons will not trigger an event for the initial
stable state. Whereas pressed buttons will trigger an event.
This is consistent with upstream's gpio-key driver that uses
the input subsystem (and dont use autorepeat).
Prior to this patch, this was handled inconsistently for interrupt-based
an polled gpio-keys. Hence this patch unifies the shared logic into the
gpio_keys_handle_button() function and modify both implementations to
handle the initial state properly.
The changes described in 2. ) . can have an impact on the
failsafe trigger. Up until now, the script checked for button
state changes. On the down side, this allowed to trigger the
failsafe by releasing a held button at the right time. On the
plus side, the button's polarity setting didn't matter.
Now, the failsafe will only engage when a button was pressed
at the right moment (same as before), but now it can
theoretically also trigger when the button was pressed the
whole time the kernel booted and well into the fast-blinking
preinit phase. However, the chances that this can happen are
really small. This is because the gpio-button module is usually
up and ready even before the preinit state is entered. So, the
initial pressed button event gets lost and most devices behave
as before.
Bisectors: If this patch causes a device to permanently go into
failsafe or experience weird behavior due to inputs, please
check the following:
- the GPIO polarity setting for the button
- the software-debounce value

Commit afc056d7dc ("gpio-button-hotplug: support interrupt

that it always misses first event, which causes issues with rc.button

Currently the generated event contains wrong seen value, when the button
is pressed for the first time:
rmmod gpio_button_hotplug; modprobe gpio_button_hotplug
[ pressing the wps key immediately after modprobe ]
gpio-keys: create event, name=wps, seen=1088, pressed=1
So this patch adds a check for this corner case and makes seen=0 if the
button is pressed for the first time.

Upstream Linux's input gpio-keys driver supports
specifying a external interrupt for a gpio via the
'interrupts' properties as well as having support
for software debounce.
This patch ports these features to OpenWrt's event
version. Only the "pure" interrupt-driven support is
left behind, since this goes a bit against the "gpio"
in the "gpio-keys" and I don't have a real device to
test this with.
This patch also silences the generated warnings showing
up since 4.14 due to the 'constification' of the
struct gpio_keys_button *buttons variable in the
upstream struct gpio_keys_platform_data declaration.

For devices such as BTHOMEHUBV5A with both reset and restart buttons,
its easily accessible restart button has been assigned to KEY_POWER
power script to poweroff preventing accidental (or malicious) factory
resets by KEY_RESTART reset script. However an easily accessible button
immediately powering off the device is also undesirable.
As KEY_RESTART is already used for reset script (and there's no
KEY_REBOOT in Linux input events), use KEY_POWER2 for rebooting via new
reboot script with 5 second seen delay.

The userspace application now uses the model=full option to match the
configuration of the kernel module. The source no longer contains SOAP
support, which was the primary reason to build only typical instead
of full before.
This makes several CLI commands, which were already supported in the
kernel module, available in the userspace application. For example, this
includes bbsg which allows to get information about VDSL2 bands.
Some previously applied build options were redundant. Disabling ADSL MIB
support is unnecessary, as it only applies to Danube. ADSL LED support
is no longer included in the source. ReTx counters are already included
with model type full.
This increases the size of the userspace application by approximately
15 kB (uncompressed). The kernel module does not change at all.

In the current state, nvmem cells are only detected on platform device.
To quickly fix the problem, we register the affected problematic driver
with the of_platform but that is more an hack than a real solution.
Backport from net-next the required patch so that nvmem can work also
with non-platform devices and rework our current patch.
Drop the mediatek and dsa workaround and rework the ath10k patches.
Rework every driver that use the of_get_mac_address api.
