At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.Move the compatibility features into a separate header file.

This currently reads the uclass's private data in the ofdata_to_platdata
method which is not allowed, since the uclass has not read it from the
device tree. This happens in the probe method.Fix it by adding a probe() method and moving the code there.

This is a generic implementation. Add CONFIG_SYSRESET_CMD_POWEROFF
to signal when we need it. Enable it from the STPMIC1 config and in
sandbox.The config flag is transitionary, that is it can be removed after all
poweroff implementations use sysreset, and just have CMD_POWEROFF depend
on sysreset.Signed-off-by: Urja Rannikko

BD71837 and BD71847 is PMIC intended for powering single-core,
dual-core, and quad-core SoC’s such as NXP-i.MX 8M. BD71847
is used for example on NXP imx8mm EVK.Add regulator driver for ROHM BD71837 and BD71847 PMICs.
BD71837 contains 8 bucks and 7 LDOS. BD71847 is reduced
version containing 6 bucks and 6 LDOs. Voltages for DVS
bucks (1-4 on BD71837, 1 and 2 on BD71847) can be adjusted
when regulators are enabled. For other bucks and LDOs we may
have over- or undershooting if voltage is adjusted when
regulator is enabled. Thus this is prevented by default.BD718x7 has a quirk which may leave power output disabled
after reset if enable/disable state was controlled by SW.
Thus the SW control is only allowed for BD71837 bucks
3 and 4 by default. The impact of this limitation must be
evaluated board-by board and restrictions may need to be
modified. (Linux driver get's these limitations from DT and we
may want to implement same on u-Boot driver).Signed-off-by: Matti Vaittinen

Improvements:
- init DRAM for RK322x in SPL
- add FAN53555 PMIC/regulator driver
- update MicroCrystal RV3029 driver to Kconfig and sync from Linux
- add bootcount uclass and first DM-driver for bootcount -
This adds a driver for the FAN53555 family of regulators and wraps it
in a PMIC implementation.While these devices support a 'normal' and 'suspend' mode (controlled
via an external pin) to switch between two programmable voltages, this
incarnation of the driver assumes that the device is always operating
in 'normal' mode.Only setting/reading the programmed voltage is supported at this time
and the following device functionality remains unsupported:
- switching the selected voltage (via a GPIO)
- disabling the voltage output via software-control
This matches the functionality of the Linux driver.Tested on a RK3399-Q7 (with 'option 5' devices): setting voltages from
the U-Boot shell and verifying output voltages on the board.Signed-off-by: Philipp Tomsich
