rtc: mt6397: select IRQ_DOMAIN instead of depending on it

2024-03-26T22:22:42+00:00

[ Upstream commit 544c42f798e1651dcb04fb0395219bf0f1c2607e ]

IRQ_DOMAIN is a hidden (not user visible) symbol. Users cannot set
it directly thru "make *config", so drivers should select it instead
of depending on it if they need it.
Relying on it being set for a dependency is risky.

Consistently using "select" or "depends on" can also help reduce
Kconfig circular dependency issues.

Therefore, change the use of "depends on" for IRQ_DOMAIN to
"select" for RTC_DRV_MT6397.

rtc: s5m: select REGMAP_I2C

2021-03-04T08:39:44+00:00

[ Upstream commit 1f0cbda3b452b520c5f3794f8f0e410e8bc7386a ]

The rtc-s5m uses the I2C regmap but doesn't select it in Kconfig so
depending on the configuration the build may fail. Fix it.

rtc: max8907: add missing select REGMAP_IRQ

2020-03-25T07:06:12+00:00

commit 5d892919fdd0cefd361697472d4e1b174a594991 upstream.

I have hit the following build error:

  rtc-max8907.c:(.text+0x400): undefined reference to `regmap_irq_get_virq'

max8907 should select REGMAP_IRQ

rtc: ds1307: simplify hwmon config

2018-08-16T05:46:41+00:00

We don't have to define an extra config symbol, IS_REACHABLE does
what we need. And having this config symbol just to save the few
bytes of hwmon support on non-DS3231 chips isn't worth it IMO
(especially as the symbol is set per default).

rtc: ds1685: remove sysfs access to control registers

2018-06-20T10:38:14+00:00

Access to the control registers is mostly not needed and can cause runtime

Merge tag 'rtc-4.17' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux

Pull RTC updates from Alexandre Belloni:
 "This contains a few series that have been in preparation for a while
  and that will help systems with RTCs that will fail in 2038, 2069 or
  2100.

  Subsystem:
   - Add tracepoints
   - Rework of the RTC/nvmem API to allow drivers to discard struct
     nvmem_config after registration
   - New range API, drivers can now expose the useful range of the RTC
   - New offset API the core is now able to add an offset to the RTC
     time, modifying the supported range.
   - Multiple rtc_time64_to_tm fixes
   - Handle time_t overflow on 32 bit platforms in the core instead of
     letting drivers do crazy things.
   - remove rtc_control API

  New driver:
   - Intersil ISL12026

  Drivers:
   - Drivers exposing the RTC non volatile memory have been converted to
     use nvmem
   - Removed useless time and date validation
   - Removed an indirection pattern that was a cargo cult from ancient
     drivers
   - Removed VLA usage
   - Fixed a possible race condition in probe functions
   - AB8540 support is dropped from ab8500
   - pcf85363 now has alarm support"

treewide: simplify Kconfig dependencies for removed archs

2018-03-26T13:55:57+00:00

A lot of Kconfig symbols have architecture specific dependencies.
In those cases that depend on architectures we have already removed,
they can be omitted.
