Pull RTC updates from Alexandre Belloni:
"A huge series from me this cycle. I went through many drivers to set
the date and time range supported by the RTC which helps solving HW
limitation when the time comes (as early as next year for some). This
time, I focused on drivers using .set_mms and .set_mmss64, allowing me
to remove those callbacks. About a third of the patches got reviews, I
actually own the RTCs and I tested another third and the remaining one
are unlikely to cause any issues.
Other than that, a single new driver and the usual fixes here and there.
Summary:
Subsystem:
- set_mmss and set_mmss64 rtc_ops removal
- Fix timestamp value for RTC_TIMESTAMP_BEGIN_1900
- Use SPDX identifier for the core
- validate upper bound of tm->tm_year
New driver:
- Aspeed BMC SoC RTC
Drivers:
- abx80x: use rtc_add_group
- ds3232: nvram support
- pcf85063: add alarm, nvram, offset correction and microcrystal
rv8263 support
- x1205: add of_match_table
- Use set_time instead of set_mms/set_mmss64 for: ab3100, coh901331,
digicolor, ds1672, ds2404, ep93xx, imxdi, jz4740, lpc32xx, mc13xxx,
mxc, pcap, stmp3xxx, test, wm831x, xgene.
- Set RTC range for: ab3100, at91sam9, coh901331, da9063, digicolor,
dm355evm, ds1672, ds2404, ep39xx, goldfish, imxdi, jz4740, lpc32xx,
mc13xxx, mv, mxc, omap, pcap, pcf85063, pcf85363, ps3, sh,
stmp3xxx, sun4v, tegra, wm831x, xgene.
- Switch to rtc_time64_to_tm/rtc_tm_to_time64 for the driver that
properly set the RTC range.
- Use dev_get_drvdata instead of multiple indirections"

This Embedded Controller has an internal RTC that is exposed
as a standard RTC class driver with read/write functionality.
The driver is added to the drivers/rtc/ so that the maintainer of that
directory will be able to comment on this change, as that maintainer is
the expert on this system. In addition, the driver code is called
indirectly after a corresponding device is registered from core.c,
as opposed to core.c registering the driver callbacks directly.

Add support for the RTC block on the 32-bit Amlogic Meson6, Meson8,
Meson8b and Meson8m2 SoCs.
The RTC is split in to two parts, which are both managed by this driver:
- the AHB front end
- and a simple serial connection to the actual registers
The RTC_COUNTER register which holds the time is 32-bits wide.
There are four 32-bit wide (in total: 16 bytes) "regmem" registers which
are exposed using nvmem. On Amlogic's 3.10 kernel this is used to store
data which needs to survive a suspend / resume cycle.

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.

This adds support for reading and writing date/time from/to ds1341 chip.
ds1341 chip has other features - alarms, input clock (can be used instead
of intercal oscillator for better accuracy), output clock ("square wave
generation"). However, not all of that is available at the same time.
Same chip pins, CLKIN/nINTA and SQW/nINTB, can be used either for
input/output clocks, or for alarm interrupts. Role of these pins on
particular board depends on hardware wiring.
We can add device tree properties that describe if each of pins is wired
as clock, or as interrupt, or left unconnected, and enable support for
corresponding functionality based on that. But that is cumbersome, requires
hardware for testing, and has to deal with bit enabling/disabling output
clock also affects which pins alarm interrupts are routed to.
Another factor is that there are hardware setups (i.e. ZII RDU2) that
power DS1341 from SuperCap, which makes power saving critical. For such
setups, kernel driver should leave register bits that control mentioned
pins in the state configured by bootloader.
Given all that, it was decided to limit support to "only date/time" for
now. That is enough for common use case. Full (and cumbersome)
implementation can be added later if ever needed.

Many RTCs have an on board non volatile storage. It can be battery backed
RAM or an EEPROM. Use the nvmem subsystem to export it to both userspace
and in-kernel consumers.
This stays compatible with the previous (non documented) ABI that was using
/sys/class/rtc/rtcx/device/nvram to export that memory. But will warn about
the deprecation.

The Gemini RTC is actually a generic IP block from Faraday
Technology names FTRTC010. Rename the driver file and all
symbols to match this IP name.
The relationship can be clearly seen in the U-Boot driver
posted by Po-Yu Chuang for the Faraday A320 board:
https://lists.denx.de/pipermail/u-boot/2009-September/061326.html
Remove the dependency on ARCH_GEMINI but select the driver
for ARCH_GEMINI so we get a smooth transition. The IP block
is synthsized on different silicon and architectures.
