As there is no real dependency on it, remove the OF dependency from the

8792bab957 rtc: armada38x: depend on OF
The driver will compile with warning without OF because armada38x_data and
armada8k_data will be defined but not used. It would be possible to move
then in the #ifdef CONFIG_OF section but then their members will be defined
but not used. Instead of moving most of the driver in the #ifdef, simply
depend on OF.

ddd0521549 rtc: zynqmp: depend on HAS_IOMEM
The Xilinx zynqmp RTC driver makes use of IOMEM functions like
devm_platform_ioremap_resource(), which are only available if
CONFIG_HAS_IOMEM is defined.

This causes the driver not to be enable under make ARCH=um allyesconfig,
even though it won't build.

By adding a dependency on HAS_IOMEM, the driver will not be enabled on
architectures which don't support it.

c5158358df rtc: mrst: Remove driver for deprecated platform
Intel Moorestown and Medfield are quite old Intel Atom based
32-bit platforms, which were in limited use in some Android phones,
tablets and consumer electronics more than eight years ago.

There are no bugs or problems ever reported outside from Intel
for breaking any of that platforms for years. It seems no real
users exists who run more or less fresh kernel on it. The commit
05f4434bc1 ("ASoC: Intel: remove mfld_machine") also in align
with this theory.

Due to above and to reduce a burden of supporting outdated drivers
we remove the support of outdated platforms completely.

It is not enough to select WATCHDOG_CORE, the watchdog part of the driver
now also depends on WATCHDOG. This is currently the best we can do because

f9b2a4d6a5 rtc: class: support hctosys from modular RTC drivers
Due to distribution constraints it may not be possible to statically
compile the required RTC driver into the kernel.

Expand RTC_HCTOSYS support to cover all RTC devices (statically compiled
or not) by checking at the end of RTC device registration whether the
time should be synced.

34719de919 rtc: i2c/spi: Avoid inclusion of REGMAP support when not needed
Merely enabling I2C and RTC selects REGMAP_I2C and REGMAP_SPI, even when
no driver needs it.  While the former can be moduler, the latter cannot,
and thus becomes built-in.

Fix this by moving the select statements for REGMAP_I2C and REGMAP_SPI
from the RTC_I2C_AND_SPI helper to the individual drivers that depend on
it.

Note that the comment for RTC_I2C_AND_SPI refers to SND_SOC_I2C_AND_SPI
for more information, but the latter does not select REGMAP_{I2C,SPI}
itself, and defers that to the individual drivers, too.

Add partial support for the watchdog functionality of

The programmable watchdog timer is currently using a fixed
clock source of 1Hz. This result in a selectable range of
1-255 seconds, which covers most embedded Linux use-cases.

Clock sources of 4096Hz, 64Hz and 1/60Hz is mostly useful
in MCU use-cases.
