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.

eth: mtk-eth: add mt7531 switch support in mediatek eth driver

mt7531 is a 7-ports switch with 5 embedded giga phys, and uses the same

net: mediatek: use regmap api to modify ethsys registers

The address returned by regmap_get_range() is not remapped. Directly r/w
to this address is ok for ARM platforms since it's idential to the virtual
address.

But for MIPS platform only virtual address should be used for access.
To solve this issue, the regmap api regmap_read/regmap_write should be used
since they will remap address before accessing.

net: mediatek: remap iobase address

The iobase address from dts node is actually physical address. It's
identical to the virtual address in ARM platform. This is ok because this
driver was used only by ARM platforms (mt7622/mt7623 ...).

But now this driver will be used by mt7621 which is a MIPS SoC. For MIPS
platform the physical address space is mapped to KSEG0 and KSEG1 and this
makes the virtual address apparently not idential to its physical address.

To solve this issue, this patch replaces dev_read_addr with dev_remap_addr
to get the remapped iobase address.

net: mediatek: remap iobase address

The iobase address from dts node is actually physical address. It's
identical to the virtual address in ARM platform. This is ok because this
driver was used only by ARM platforms (mt7622/mt7623 ...).

But now this driver will be used by mt7621 which is a MIPS SoC. For MIPS
platform the physical address space is mapped to KSEG0 and KSEG1 and this
makes the virtual address apparently not idential to its physical address.

To solve this issue, this patch replaces dev_read_addr with dev_remap_addr
to get the remapped iobase address.

However the driver used ofnode_find_subnode("phy-handle") to read the node.
It will always fail.

This patch replaces ofnode_find_subnode with dev_read_phandle_with_args to
make sure the node can be read correctly.

dm: treewide: Rename 'platdata' variables to just 'plat'

We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private

Rename some of the latter variables to end with 'plat' for consistency.

dm: treewide: Rename auto_alloc_size members to be shorter

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

eth: mtk-eth: enable mt7629 sgmii mode support in mediatek eth driver

The sgmii mode init flow is almost the same for all mediatek SoC, the
only difference is the register offset(SGMSYS_GEN2_SPEED) is 0x2028
in the old chip(mt7622) but changed to 0x128 for the newer chip(mt7629

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.
