Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

2024-05-19T14:16:36+00:00

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

input: button_kbd: gracefully handle buttons that fail probe

2024-04-18T22:37:10+00:00

If a button device fails to probe, it will still be added to the uclass
device list, and therefore will still be iterated over in
button_read_keys() resulting in a UAF on the buttons private data.

Resolve this by unbinding button devices that aren't active after
probing, and print a warning so it's clear that the button is broken.

input: avoid NULL dereference

2023-10-11T14:35:24+00:00

Before using the result of env_get("stdin") we must check if it is NULL.

Avoid #if. This resolves the -Wunused-but-set-variable issue and we don't
need a dummy assignment in the else branch. Anyway this warning is
disabled in the Makefile.

For sake of readability use an early return after the configuration check.

Checking CONFIG_SPL_BUILD is incorrect as env_get() is only defined if
CONFIG_$(SPL_TPL)ENV_SUPPORT=y.

input: Flush the keyboard buffer before resetting it

2023-05-11T02:25:29+00:00

If U-Boot is not the first-stage bootloader the keyboard may already be
set up. Make sure to flush any data before trying to reset it. This
avoids a long timeout / hang.

Add some comments and a log category while we are here.

input: button_kbd: make driver complementary to gpio buttons

2023-03-30T19:09:59+00:00

Remove need of dts binding for button keyboard since it reuses
gpio-keys binding. Select gpio-keys driver if button keyboard
is selected since button keyboard can not operate on its own.

dm: input: add button_kbd driver

2023-02-10T18:41:06+00:00

Bootmenu requires an input device with arrows and enter key.
A common smartphone luckily has power, volume up/down buttons,
which may be used for controlling bootmenu.
To use driver, add 'button-kbd' to stdin.

input: apple: Add support for Apple SPI keyboard

2022-02-10T21:44:23+00:00

This driver adds support for the keyboard on Apple Silicon laptops.
The controller for this keyboard sits on an SPI bus and uses an
Apple-specific HID over SPI protocol. The packets sent by this
controller for key presses and key releases are fairly simple and
are decoded directly by the code in this driver and converted into
standard Linux keycodes. The same controller handles the touchpad
found on these laptops.  Packets for touchpad events are simply
ignored.
