9f6649209f net: Move network rules to drivers/net
The code under drivers/net is related to ethernet networking drivers, in
some fashion or another.  Drop these from the top-level Makefile and
also move the phy rule into drivers/net/Makefile which is where it
belongs.  Make the new rule for drivers/net check for the build-stage
relevant ETH symbol.

Fix up some Kconfig dependencies while we're here to mirror how the
Makefile logic now works.

a4faf1f563 power: Refactor Makefile rules
Move the power/ rules into drivers/power to avoid clutter in the Makefile
and drivers/Makefile files.

We must select SPL_POWER if SPL_POWER_DOMAIN is used, since the two are
currently independent and boards do not necessarily enable SPL_POWER.

Add a TPL_POWER as well, as that is used by one board.

14c251ffe1 power: Add a POWER config
At present we have SPL_POWER but not piain POWER. This works because
there is a special build rule in Makefile that always includes the
drivers/power directory.

It is better to have all driver directories included by drivers/Makefile
and there is already a rule in there for this purpose. It just needs a
Kconfig for U-Boot proper, so add one.

Update the pmic.h header file so that it defines the old pmic struct
always, when driver model is not in use. That will avoid build errors
for boards which enable POWER but not DM_PMIC.

Enable this option always. That seems strange at first sight, but it
actually but mimics the current Makefile behaviour. Once we can drop the
old PMICs it should be easy enough to rename DM_PMIC to POWWER, or
something similar.

9d8665b709 i2c: Convert CONFIG_POWER_I2C et al to Kconfig
This converts the following to Kconfig:
   CONFIG_POWER_I2C
   CONFIG_POWER_LEGACY

They are handled at the same time due to a dependency between them.
Update the Makefile rule to use legacy power only in U-Boot proper.
Unfortunately a separate rule is needed in SPL to be able to build
legacy power.  Add SPL related symbols for both, to allow for SPL-only
usage.

29d7153ec3 power: Rename CONFIG_POWER to CONFIG_POWER_LEGACY
This option is used in pre-driver model code and much of it has never
been converted to driver model.

We want to add a new option to enable power support, so we can use a
simple rule in the Makefile. Rename this one, which is really about
a particular implementation of power.

Also update the pmic.h header file so it either includes the legacy
API or the driver model one.

223c44904d rtc: ds1307: Fix incorrect clock reset for DS13xx
The ds1307 driver also supports the DS1339 and DS1340.
However, in ds1307_rtc_reset the register writes assume that the chip
is a DS1307. This is evident in the writing of bits SQWE, RS1, RS0 to
the control register. While this applies correctly to the DS1307, on a
DS1340 the control register doesn't contain those bits (instead, the
register is used for clock calibration). By writing these bits the
clock calibration will be changed and the chip can become
non-functional after a reset call.

2ac8490412 watchdog: add gpio watchdog driver
A rather common kind of external watchdog circuit is one that is kept
alive by toggling a gpio. Add a driver for handling such a watchdog.

The corresponding linux driver apparently has support for some
watchdog circuits which can be disabled by tri-stating the gpio, but I
have never actually encountered such a chip in the wild; the whole
point of adding an external watchdog is usually that it is not in any
way under software control. For forward-compatibility, and to make DT
describe the hardware, the current driver only supports devices that
have the always-running property. I went a little back and forth on
whether I should fail ->probe or only ->start, and ended up deciding
->start was the right place.

The compatible string is probably a little odd as it has nothing to do
with linux per se - however, I chose that to make .dts snippets
reusable between device trees used with U-Boot and linux, and this is
the (only) compatible string that linux' corresponding driver and DT
binding accepts. I have asked whether one should/could add "wdt-gpio"
to that binding, but the answer was no:

  https://lore.kernel.org/lkml/CAL_JsqKEGaFpiFV_oAtE+S_bnHkg4qry+bhx2EDs=NSbVf_giA@mail.gmail.com/

If someone feels strongly about this, I can certainly remove the
"linux," part from the string - it probably wouldn't the only place where
one can't reuse a DT snippet as-is between linux and U-Boot.

492ee6b8d0 watchdog: wdt-uclass.c: handle all DM watchdogs in watchdog_reset()
A board can have and make use of more than one watchdog device, say
one built into the SOC and an external gpio-petted one. Having
wdt-uclass only handle the first is both a little arbitrary and
unexpected.

So change initr_watchdog() so we visit (probe) all DM watchdog
devices, and call the init_watchdog_dev helper for each.

Similarly let watchdog_reset() loop over the whole uclass - each
having their own ratelimiting metadata, and a separate "is this device
running" flag.

This gets rid of the watchdog_dev member of struct global_data.  We
do, however, still need the GD_FLG_WDT_READY set in
initr_watchdog(). This is because watchdog_reset() can get called
before DM is ready, and I don't think we can call uclass_get() that
early.

The current code just returns 0 if "getting" the first device fails -
that can of course happen because there are no devices, but it could
also happen if its ->probe call failed. In keeping with that, continue
with the handling of the remaining devices even if one fails to
probe. This is also why we cannot use uclass_probe_all().

If desired, it's possible to later add a per-device "u-boot,autostart"
boolean property, so that one can do CONFIG_WATCHDOG_AUTOSTART
per-device.

This driver uses the CONFIG namespace to set the chips internal CONFIG
namespace related bits.  However, CONFIG is reserved for the top-level
Kconfig based configuration system.  Use CFG as the namespace here
instead to avoid pollution.

6d5d0c955e i2c: fsl_i2c: Migrate to Kconfig
- As there are no boards that use different values for speed / slave on
  different buses, use a single option.
- Switch to using the common SYS_I2C_SPEED / SYS_I2C_SLAVE options.
- Introduce _HAS_ options for additional buses as only the first one is
  common to all users.
- Convert all remaining symbols to Kconfig.
