Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

imx8: Replace SC_R_LAST with SC_R_NONE in DTB

We are currently using SC_R_LAST as a marker for imx8 power domain tree
nodes without a resource attached. This value is compiled into dtb as
part of the linux build and used by uboot.

The SC_R_LAST constant changes frequently as SCFW resources are added
(by design) and every time we need to update linux and uboot headers
together or boot can fail.

Fix this by replacing SC_R_LAST usage with a new constant SC_R_NONE

imx: imx8qm/imx8qxp: Power down the resources before SPL jump to u-boot

Make sure that all devices that are powered up by SPL are powered down
before entering into the u-boot. Otherwise the subsystem/device will
never be powered down by SCFW, due to SPL and u-boot are in different
partitions.

Benefiting from power domain driver, this patch implements the function
"imx8_power_off_pd_devices" to power off all active devices.

imx8: Replace SC_R_LAST with SC_R_NONE in DTB

We are currently using SC_R_LAST as a marker for imx8 power domain tree
nodes without a resource attached. This value is compiled into dtb as
part of the linux build and used by uboot.

The SC_R_LAST constant changes frequently as SCFW resources are added
(by design) and every time we need to update linux and uboot headers
together or boot can fail.

Fix this by replacing SC_R_LAST usage with a new constant SC_R_NONE
defined to be 0xFFF0.

power: imx8: remove the resource owned check before power off

For all the devices used and set ACTIVE in U-Boot, U-Boot needs

When we create software partition before booting Linux, the resource

the other software partition could be powered off with parent

imx8: power: Add PD device lookup interface to power domain uclass

Add power_domain_lookup_name interface to power domain uclass to find
a power domain device by its DTB node name, not using its associated
client device.

Through this interface, we can operate the power domain devices directly.
This is needed for non-DM drivers.

Modified from Ye's NXP downstream patch

only for legacy imx8 power domain driver, since we have not migrated
to use new power domain driver.

dm: core: Create a new header file for 'compat' features

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.

power-domain: Rename free() to rfree()

power: domain: make imx8-power-domain.c legacy

The current i.MX8 power domain driver is based on i.MX vendor
power domain tree which will retire later.

The Linux upstream use a single pd node for power domain driver,
and U-Boot will adopt that. When U-Boot i.MX8 dts synced with
Linux Kernel upstream and related driver ready, the legacy

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

dm: treewide: Rename auto_alloc_size members to be shorter

This construct is quite long-winded. In earlier days it made some sense

verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,

imx: imx8qm/imx8qxp: Power down the resources before SPL jump to u-boot

Make sure that all devices that are powered up by SPL are powered down
before entering into the u-boot. Otherwise the subsystem/device will
never be powered down by SCFW, due to SPL and u-boot are in different
partitions.

Benefiting from power domain driver, this patch implements the function

imx8: Replace SC_R_LAST with SC_R_NONE in DTB

We are currently using SC_R_LAST as a marker for imx8 power domain tree
nodes without a resource attached. This value is compiled into dtb as
part of the linux build and used by uboot.

The SC_R_LAST constant changes frequently as SCFW resources are added
(by design) and every time we need to update linux and uboot headers
together or boot can fail.

Fix this by replacing SC_R_LAST usage with a new constant SC_R_NONE
defined to be 0xFFF0.
