Currently when booting the kernel on i.MX8 U-Boot hangs in an
endless loop when switching off dma, connectivity or lsio power
domains during device removal. It hapens first when removing
gpio0 (gpio@5d080000) device, here its power domain device
'lsio_gpio0' is obtained for switching off power. Since the
obtained 'lsio_gpio0' device is removed afterwards, its power
domain is also switched off and here the parent power domain
device 'lsio_power_domain' is optained for switching off the
power. Thereafter, when the obtained 'lsio_power_domain' is
removed, device_remove() removes its first child 'lsio_gpio0'.
During this child removal the 'lsio_power_domain' device is
obtained again for switching and when removing it later,
the same child removal is repeated, so we are stuck in an
endless loop. Below is a snippet from dm tree on i.MX8QXP
for better illustration of the DM devices relationship:Class Index Probed Driver Name

New driver model core utility functions -
The commit e8e9715df2d4 ("regulator: fixed: Modify enable-active-high behavior")
fixed the regulator driver behavior when 'enable-active-high' is defined.
Unfortunately, this patch used dm_regulator_platdata()'s "boot_on" member
to set GPIOD_IS_OUT_ACTIVE flag and enable the regulator.The issue here is that regulator_common_ofdata_to_platdata() is called
_before_ regulator_pre_probe() function in which the 'regulator-boot-on'
property is asserted.As a result the GPIOD_IS_OUT_ACTIVE flag is not set and gpio_request_by_name()
called in the former function is not enabling the regulator.
This is problematic for e.g. i.MX ethernet driver, which then tries to
perform initialization without power (and fails).The solution here is to explicitly enable regulator in regulator_pre_probe()
callback only when 'regulator-boot-on' property is present in device tree.
The GPIOD_IS_OUT_ACTIVE flag is not set at all, but relevant gpio is
requested.Signed-off-by: Lukasz Majewski

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.

At present devres.h is included in all files that include dm.h but few
make use of it. Also this pulls in linux/compat which adds several more
headers. Drop the automatic inclusion and require files to include devres
themselves. This provides a good indication of which files use devres.Signed-off-by: Simon Glass

This currently reads the uclass's private data in the ofdata_to_platdata

commit 29f7d05a347a ("dm: core: Move ofdata_to_platdata() call earlier")
introduces changes in the order of device_probe execution.
ofdata_to_platdata now comes before the probe function which resulted in
a deadlock and caused boot hang on AM6 devices.Deadlock sequence: tps62360_regulator_ofdata_to_platdata --> i2c_get_chip
--> device_probe(tps62360) --> tps62360_regulator_ofdata_to_platdataHence convert ofdata_to_platdata to the missing probe function to fix the
hang.Fixes: 22e8f18980d6 ("power: regulator: tps6236x: add support for tps6236x regulators")

The power domain tree is not accepted by Linux Kernel upstream.
only a single pd node is used currently, as following:pd: imx8qx-pd {
compatible = "fsl,imx8qm-scu-pd", "fsl,scu-pd";
#power-domain-cells = ;
};So to migrate to use upstream linux dts, we also need a driver
to support this.This patch is to support the new method, compared with legacy power
domain tree, it will be simpiler, because each device will
has resource id as power domain index, it will be directly passed
to scfw, and no need to let power domain build that tree. If multiple
power domain is needed, it is the dts node should has correctly power
domains entry added and sequence correct.Signed-off-by: Peng Fan
