Subject: [GIT PULL] RTC for 6.16
Hello Linus,
Here is the RTC subsystem pull request for 6.16. There are two new drivers this
cycle. There is also support for a negative offset for RTCs that have been
shipped with a date set using an epoch that is before 1970. This unfortunately
happens with some products that ship with a vendor kernel and an out of tree
driver.
The following changes since commit 0af2f6be1b4281385b618cb86ad946eded089ac8:
Linux 6.15-rc1 (2025-04-06 13:11:33 -0700)
are available in the Git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux.git tags/rtc-6.16
