staging: nvec: make touchpad init synchronous

2024-04-11T11:59:19+00:00

Currently, we are constantly sending commands to the EC without waiting for them to be
executed. For the touchpad initialization this only worked because we were waiting 200 µs
between each submitted command byte, so the EC had enough time to execute. In the furture
we like to avoid this delay, so we need to wait for each command to be executed first.
Do this by switching from asynchronous to synchronous command transmission.

staging: nvec: make keyboard init synchronous

2024-04-11T11:59:19+00:00

Currently, we are constantly sending commands to the EC without waiting for them to be
executed. This can lead to confusion, especially if we initialize several different devices
one after the other.
To avoid this, we are switching from asynchronous to synchronous command transmission.

staging: nvec: add ability to ignore EC responses in sync writes

2024-04-11T11:59:19+00:00

In case we just want to submit a message to the EC but are not
interested in its response, we can free the response buffer early.

2024-04-09T15:51:16+00:00

This commit corrects the spelling of "initialisation" which was
misspelled as "intialisation" in the irqreturn_t nvec_interrupt()
documentation.
The issue was found using checkpatch.

staging: nvec_ps2: Convert to platform remove callback returning void

2023-04-03T19:49:55+00:00

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.
