It is better to select M0 and M1 iomux by gmac_rxd0, the
gmac_rxd0 would be used at RGMII and RMII.

Because there are two gmac controllers at rk3568, use
bus id to set the corresponding registers respectively.

This patch fixes the following issues for rk3568 usb2 phy.
1. Only enable the id irq and bvalid irq for the port of combphy
which used shared interrupt and work as otg/peripheral mode.
2. Enable the DP/DM pulldown resistors for the port of combphy
if the port is used for usb host controller.
3. Set utmi opmode to no-driving for rk3568 usb phy when usb
phy enter suspend mode via usb phy grf. It can help to
avoid triggering the linestate irq constantly.

When a host system has kernel headers that are newer than a compiling
kernel, mksyscalltbl fails with errors such as:
<stdin>: In function 'main':
<stdin>:271:44: error: '__NR_kexec_file_load' undeclared (first use in this function)

tools/perf/arch/arm64/entry/syscalls//mksyscalltbl: line 48: /tmp/create-table-xvUQdD: Permission denied
mksyscalltbl is compiled with default host includes, but run with
compiling kernel tree includes, causing some syscall numbers to being
undeclared.
Committer testing:
Before this patch, in my cross build environment, no build problems, but
these new syscalls were not in the syscalls.c generated from the
unistd.h file, which is a bug, this patch fixes it:
perfbuilder@6e20056ed532:/git/perf$ tail /tmp/build/perf/arch/arm64/include/generated/asm/syscalls.c

[293] = "rseq",

[424] = "pidfd_send_signal",

[426] = "io_uring_enter",

};

Well, there is that last "syscalls" thing, but that looks like some
other bug.

DPTPHYT22ULP is designed for chips that perform eDP/DP data
communication while operating at low power consumption.
The main link is a multi-gigabit transmitter macro which
enable speed up to 4.0Gbps data transmitter with optimized
power and die size, also it can be easily fabricated and
implemented in a video system. The AUX channel is a halfduplex,
bidirectional channel consisting of one differential pair,
supporting the bit rate of about 1Mbps.
Macro consists of multi-main link transmitter channels,
AUX channel, one PLL and bias-gen unit. The main link
transmitter performs dedicated P2S, clock generator,
driver with preemphasis and self-test. Each of the channels
can be turned off individually.

Allow DisplayPort PHYs to be configured through the generic
functions through a custom structure added to the generic union.
The configuration structure is used for reconfiguration of
DisplayPort PHYs during link training operation.
The parameters added here are the ones defined in the DisplayPort
spec v1.4 which include link rate, number of lanes, voltage swing
and pre-emphasis.
Add the DisplayPort phy mode to the generic phy_mode enum.

Now that we have some infrastructure for it, allow the MIPI D-PHY phy's to
be configured through the generic functions through a custom structure
added to the generic union.
The parameters added here are the ones defined in the MIPI D-PHY spec, plus
the number of lanes in use. The current set of parameters should cover all
the potential users.

(cherry picked from commit 2ed869990e)
The phy framework is only allowing to configure the power state of the PHY
using the init and power_on hooks, and their power_off and exit
counterparts.
While it works for most, simple, PHYs supported so far, some more advanced
PHYs need some configuration depending on runtime parameters. These PHYs
have been supported by a number of means already, often by using ad-hoc
drivers in their consumer drivers.
That doesn't work too well however, when a consumer device needs to deal
with multiple PHYs, or when multiple consumers need to deal with the same
PHY (a DSI driver and a CSI driver for example).
So we'll add a new interface, through two funtions, phy_validate and
phy_configure. The first one will allow to check that a current
configuration, for a given mode, is applicable. It will also allow the PHY
driver to tune the settings given as parameters as it sees fit.
phy_configure will actually apply that configuration in the phy itself.
