Several months ago, this blog post appeared in a search. In summary, this post outlines the new char device-based GPIO interfaces. It further states that a full complement of features will be available with the release of the 5.5 Linux kernel, and libgpiod
ver 1.5.
Since reading this announcement, I've been expecting to see a more-or-less official schedule from the RPi Organization announcing a date for release of these upgrades. I've probably just missed the announcement, but I've seen nothing at all on this through raspberrypi.org.
I have two questions:
Has there been an "official" announcement on the expected release date?
Is there a reasonably safe & straightforward method for upgrading to the 5.5 kernel and libgpiod 1.5? For example:
rpi-update
??
I'd like to hear from anyone who has tried this upgrade.
sysfs
interface to GPIO has been deprecated & will be removed from the kernel? If so, what result?
