Input: matrix_keypad - remove support for platform data

2024-09-06T04:43:42+00:00

There are no more users of struct matrix_keypad_platform_data in the
kernel, remove support for it from the driver.

Input: navpoint - remove driver

2024-01-18T23:21:00+00:00

This driver does not use the SPI core as it should, instead tampering
with the SSP registers manually. Refactoring the driver is almost
certainly not worth it as the hardware seems to have been designed for
and used only in the HP iPAQ hx4700 removed more than a year ago in
d6df7df7ae5a ("ARM: pxa: remove unused board files"), so let's remove
it.

Input: as5011 - convert to GPIO descriptor

2023-12-14T05:26:13+00:00

This driver does not have any in-tree users but is passing a
legacy GPIO number through platform data.

Convert it to use a GPIO descriptor, new users or outoftree
users can easily be implemented using GPIO descriptor tables
or software nodes.

Input: navpoint - convert to use GPIO descriptor

2023-12-14T05:26:13+00:00

The Navpoint driver uses a GPIO line, convert this to use
a GPIO descriptor. There are no in-kernel users but out of tree
users can easily be added or converted using a GPIO descriptor
table as with numerous other drivers.

Input: mt - annotate struct input_mt with __counted_by

2023-09-30T16:24:17+00:00

Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for struct input_mt.

Input: matrix_keypad - replace header inclusions by forward declarations

2023-02-24T06:12:47+00:00

When the data structure is only referred by pointer, compiler may not need
to see the contents of the data type. Thus, we may replace header inclusions
by respective forward declarations.

Input: auo-pixcir-ts - drop support for platform data

2022-09-16T13:38:50+00:00

Currently there are no users of auo_pixcir_ts_platdata in the mainline, and
having it (with legacy gpio numbers) prevents us from converting the driver
to gpiod API, so let's drop it.

If, in the future, someone wants to use this driver on non-device tree,
non-ACPI system, they should use static device properties instead of
platform data.

Input: extract ChromeOS vivaldi physmap show function

2022-03-15T04:11:09+00:00

Let's introduce a common library file for the physmap show function
duplicated between three different keyboard drivers. This largely copies
the code from cros_ec_keyb.c which has the most recent version of the
show function, while using the vivaldi_data struct from the hid-vivaldi
driver. This saves a small amount of space in an allyesconfig build.
