rtc: add i.MX system controller RTC support

2018-12-20T11:47:40+00:00

i.MX8QXP is an ARMv8 SoC which has a Cortex-M4 system controller
inside, the system controller is in charge of controlling power,
clock and secure rtc etc..

This patch adds i.MX system controller RTC driver support,
Linux kernel has to communicate with system controller via MU
(message unit) IPC to set/get RTC time and other alarm functions,
since the RTC set time needs to be done in secure EL3 mode (required
by system controller firmware) and alarm functions needs to be done
with general MU IRQ handle, these depend on other components which
are NOT ready, so this patch ONLY enables the RTC time read.

rtc: ds1685: drop RTC_DS1685_PROC_REGS

2018-09-28T12:21:00+00:00

/proc is not the correct ABI to display debugging info. Remove
RTC_DS1685_PROC_REGS as the driver hasn't seen any real development since
it was included.

rtc: abx80x: add basic watchdog support

2018-09-12T10:02:21+00:00

The abx804 and abx805 chips have support for a simple watchdog
function that can trigger an external reset.

rtc: jz4740: Drop dependency on MACH_INGENIC

2018-08-27T20:59:37+00:00

Depending on MACH_INGENIC prevent us from creating a generic kernel that
works on more than one MIPS board. Instead, we just depend on MIPS being
set.

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
issues (like missed interrupts). Remove this debugging interface.

2018-04-10T17:22:27+00:00

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"
