Their specifications are as follows：
1. The RK809 and RK809 consist of 5 DCDCs, 9 LDOs
and have the same registers for these components except dcdc5.
2. The dcdc5 is a boost dcdc for RK817 and is a buck for RK809.

The SoC R40 AHCI controller need a PHY regulator to work.
But since the PHY is embedded in the controller, we cannot do a DT node for it,
since phy-supply works only in node with a PHY compatible.
So this patch adds a way to add an optional phy-supply regulator on AHCI
controller node.

Previously, during swapout, all PMD page mapping will be split and
replaced with PTE swap mapping. And when clearing the SWAP_HAS_CACHE
flag for the huge swap cluster in put_swap_page(), the huge swap
cluster will be split. Now, during swapout, the PMD page mappings to
the THP will be changed to
To support to swapin the THP in one piece, we need to create PMD swap
mapping during swapout, and maintain PMD swap mapping count. This
patch implements the support to increase the PMD swap mapping
count (for swapout, fork, etc.) and set SWAP_HAS_CACHE flag (for
swapin, etc.) for a huge swap

The Ocelot switch has currently an hardcoded SerDes muxing that suits only
a particular use case. Any other board setup will fail to work.
To prepare for upcoming boards' support that do not have the same muxing,
create a PHY driver that will handle all possible cases.
A SerDes can work in
Since HSIO address space can be accessed by different drivers, let's
simplify the register address definitions so that it can be easily used
by all drivers and put the register address definition in the
include/soc/mscc/ocelot_hsio.h header file.

The Microsemi Ocelot can mux SerDes lanes (aka macros) to different
switch ports or even make it act as a PCIe interface.
This adds support for the muxing of the SerDes.

In the reboot burning test, if some Multimedia HW has something wrong,
It may keep send the invalid request to IOMMU. In order to avoid
affect the reboot flow, we add the shutdown callback to disable
M4U HW when shutdown.

This is the final step of the THP swapin support. When reclaiming a
anonymous THP, after allocating the huge swap cluster and add the THP
into swap cache, the PMD page mapping will be changed to the mapping
to the swap space. Previously, the PMD page mapping will be split
before being changed.
When madvise_free() found a PMD swap mapping, if only part of the huge
swap cluster is operated on, the PMD swap mapping will be split and
fallback to PTE swap mapping processing. Otherwise, if all huge swap
cluster is operated on, free_swap_and_cache() will be called to
decrease the PMD swap
When splitting a THP in swap cache or failing to allocate a THP when
swapin a huge swap cluster, the huge swap cluster will be split. In
addition to clear the huge flag of the swap cluster, the PMD swap
mapping count recorded in cluster_count() will be set to 0. But we
will not touch PMD swap
The help of CONFIG_THP_SWAP is updated to reflect the latest progress
of THP (Tranparent Huge Page) swap optimization.

Currently, "the swap entry" in the page tables is used for a number of
things outside of actual swap, like page migration, etc. We support
the THP/PMD "swap entry" for page migration currently and the
functions behind this are tied to page migration's config
option
2 new /proc/vmstat fields are added, "thp_swapin" and
"thp_swapin_fallback" to count swapin a THP from swap device in one
piece and fallback to normal page swapin.

During swapoff, for a huge swap cluster, we need to allocate a THP,
read its contents into the THP and unuse the PMD and PTE swap mappings
to it. If failed to allocate a THP, the huge swap cluster will be
split.
During unuse, if it is found that the swap cluster mapped by a PMD
swap mapping is
