Subject: [GIT PULL] RTC for 5.18
Hello Linus,
Here is the RTC subsystem pull request for 5.18. The bulk of the patches
are about replacing the uie_unsupported strcut rtc_device member by a
feature bit.
I also carry patches for the clk subsystem as they have the proper acks.
The following changes since commit e783362eb54cd99b2cac8b3a9aeac942e6f6ac07:
Linux 5.17-rc1 (2022-01-23 10:12:53 +0200)
are available in the Git repository at:
git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux.git tags/rtc-5.18

rtc: check if __rtc_read_time was successful (2022-03-29 22:45:50 +0200)
----------------------------------------------------------------
RTC for 5.18
Subsystem:
- remove uie_unsupported, all users have been converted to clear
RTC_FEATURE_UPDATE_INTERRUPT and provide a reason
- RTCs with an alarm with a resolution of a minute are now letting the core
handle rounding down the alarm time
- fix use-after-free on device removal
New driver:
- OP-TEE RTC PTA
Drivers:
- sun6i: Add H616 support
- cmos: Fix the AltCentury for AMD platforms
- spear: set range
----------------------------------------------------------------
