Subject: input: ps2-gpio: use ktime for IRQ timekeeping
Date: Fri, 11 Feb 2022 22:22:55 +0100 [thread overview]
Message-ID: <20220211212258.80345-1-danilokrummrich@dk-develop.de> (raw)
This patch series implements the usage of ktime for IRQ timekeeping to
overcome:
(1) The resolution limitations of jiffies.
(2) Potential spurious IRQs generated by gpio controllers.
Besides that, based on the newly implemented timekeeping, it fixes a wrongly
suspected extra clock cycle for TX transfers and a race condition when
starting an immediate TX transfer based on data received from an RX transfer.
