[GIT PULL] RTC for 6.16

[Alexandre Belloni <alexandre.belloni@bootlin.com>]

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:
