On the some rockchip SOCS, some things like rk3399 specific uart2 can use
multiple pins. Somewhere between the pin io-cells and the uart it seems
to have some sort of switch to decide to which pin to actually route the
data.
+-------+ +--------+ /- GPIO4_B0 (pinmux 2)
| uart2 | -- | switch | --- GPIO4_C0 (pinmux 2)
+-------+ +--------+ \- GPIO4_C3 (pinmux 2)
(switch selects one of the 3 pins base on the GRF_SOC_CON7[BIT0, BIT1])
The routing switch is determined by one pin of a specific group to be set
to its special pinmux function. If the pinmux setting is wrong for that
pin the ip block won't work correctly anyway.

We need to avoid calling regmap functions from irq handlers, so the next
commit is going to move the call to rockchip_set_mux() into an
irq_bus_sync_unlock handler. But we can't return an error from there so
we still need to check the settings from rockchip_irq_set_type() and we
will use this new rockchip_verify_mux() function from there.

The DP83867 when not properly bootstrapped - especially with LED_0 pin -
can enter N/A MODE4 for "port mirroring" feature.
To provide normal operation of the PHY, one needs not only to explicitly
disable the port mirroring feature, but as well stop some IC internal
testing (which disables RGMII communication).
To do that the STRAP_STS1 (0x006E) register must be read and RESERVED bit
11 examined. When it is set, the another RESERVED bit (11) at PHYCR
(0x0010) register must be clear to disable testing mode and enable RGMII
communication.
Thorough explanation of the problem can be found at following e2e thread:
"DP83867IR: Problem with RESERVED bits in PHY Control Register (PHYCR) -
Linux driver"

This patch adds support for enabling or disabling the lane swapping (called
"port mirroring" in PHY's CFG4 register) feature of the DP83867 TI's PHY
device.
One use case is when bootstrap configuration enables this feature (because
of e.g. LED_0 wrong wiring) so then one needs to disable it in software
(at u-boot/Linux).

For proper IRQ generation by DP83867 phy the INT/PWDN pin has to be
programmed as an interrupt output instead of a Powerdown input in
Configuration Register 3 (CFG3), Address 0x001E, bit 7 INT_OE = 1. The
current driver doesn't do this and as result IRQs will not be generated by
DP83867 phy even if they are properly configured in DT.
Hence, fix IRQ generation by properly configuring CFG3.INT_OE bit and
ensure that Link Status Change (LINK_STATUS_CHNG_INT) and Auto-Negotiation
Complete (AUTONEG_COMP_INT) interrupt are enabled. After this the DP83867
driver will work properly in interrupt enabled mode.

This patch adds 1.5~2ms delay afer resume USB2 PHY, the
time for utmi_clk provided from USB2 PHY to stabilize,
and then we can access the usb core registers safely, it
can avoid system hung.
Also, we avoid to call otg20_hcd_connect_detect() if dwc2
is host mode except force host mode during probe, because
we will do the same work in check_id_work() later. This can
fix the issue that init usb core and host twice when boot
