Input: rk805-pwrkey - fix module autoloading

2022-09-08T09:11:38+00:00

[ Upstream commit 99077ad668ddd9b4823cc8ce3f3c7a3fc56f6fd9 ]

Add the module alias so the rk805-pwrkey driver will
autoload when built as a module.

Input: soc_button_array - also add Lenovo Yoga Tablet2 1051F to dmi_use_low_level_irq

2022-06-22T12:13:14+00:00

[ Upstream commit 6ab2e51898cd4343bbdf8587af8ce8fbabddbcb5 ]

Commit 223f61b8c5ad ("Input: soc_button_array - add Lenovo Yoga Tablet2
1051L to the dmi_use_low_level_irq list") added the 1051L to this list
already, but the same problem applies to the 1051F. As there are no
further 1051 variants (just the F/L), we can just DMI match 1051.

Tested on a Lenovo Yoga Tablet2 1051F: Without this patch the
home-button stops working after a wakeup from suspend.

Input: sparcspkr - fix refcount leak in bbc_beep_probe

2022-06-09T08:21:17+00:00

[ Upstream commit c8994b30d71d64d5dcc9bc0edbfdf367171aa96f ]

of_find_node_by_path() calls of_find_node_opts_by_path(),
which returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.

Input: cm109 - do not stomp on control URB

2020-12-11T21:17:36+00:00

We need to make sure we are not stomping on the control URB that was
issued when opening the device when attempting to toggle buzzer.
To do that we need to mark it as pending in cm109_open().

Input: soc_button_array - add Lenovo Yoga Tablet2 1051L to the dmi_use_low_level_irq list

2020-12-07T06:12:43+00:00

Add the Lenovo Yoga Tablet2 1051L to the list of devices where the
ACPI AML code is poking the GPIO config register directly changing
the IRQ type to a low_level_irq, which we need to work around.

This fixes the home button on the Lenovo Yoga Tablet2 1051L not
working.

Input: soc_button_array - work around DSDTs which modify the irqflags

2020-09-14T06:08:48+00:00

Some 2-in-1s which use the soc_button_array driver have this ugly issue in
their DSDT where the _LID method modifies the irq-type settings of the
GPIOs used for the power and home buttons. The intend of this AML code is
to disable these buttons when the lid is closed.

The AML does this by directly poking the GPIO controllers registers. This
is problematic because when re-enabling the irq, which happens whenever
_LID gets called with the lid open (e.g. on boot and on resume), it sets
the irq-type to IRQ_TYPE_LEVEL_LOW. Where as the gpio-keys driver programs
the type to, and expects it to be, IRQ_TYPE_EDGE_BOTH.

This commit adds a workaround for this which (on affected devices) does
not set gpio_keys_button.gpio on these 2-in-1s, instead it gets the irq for
the GPIO, configures it as IRQ_TYPE_LEVEL_LOW (to match how the _LID AML
code configures it) and passes the irq in gpio_keys_button.irq.

Input: soc_button_array - add support for INT33D3 tablet-mode switch devices

2020-09-14T06:08:47+00:00

According to the Microsoft documentation for Windows 8 convertible
devices, these devices should implement a PNP0C60 "laptop/slate mode state
indicator" ACPI device.

This device can work in 2 ways, if there is a GPIO which directly
indicates the device is in tablet-mode or not then the direct-gpio mode
should be used. If there is no such GPIO, but instead the events are
coming from e.g. the embedded-controller, then there should still be
a PNP0C60 ACPI device and event-injection should be used to send the
events. The drivers/platform/x86/intel-vbtn.c code is an example from
a standardized manner of doing the latter.

On various 2-in-1s with either a detachable keyboard, or with 360°
hinges, the direct GPIO mode is indicated by an ACPI device with a
HID of INT33D3, which contains a single GpioInt in its ACPI resource
table, which directly indicates if the device is in tablet-mode or not.

This commit adds support for this to the soc_button_array code, as
well as for the alternative ID9001 HID which some devices use
instead of the INT33D3 HID.

Input: soc_button_array - add active_low setting to soc_button_info

2020-09-14T06:08:46+00:00

This is a preparation patch for adding support for Intel INT33D3
ACPI devices. These INT33D3 devices follow yet another Intel defined
(but not documented) ACPI GPIO button standard.

Unlike the ACPI GPIO button devices supported so far, the GPIO used in
the INT33D3 devices is active-high, rather then active-low.

This commit makes setting the gpio_keys_button.active_low flag
configurable through the soc_button_info struct and enables it for all
currently supported devices.
