The SERDES0 and SERDES1 instances of SERDES on J722S are single lane
SERDES which are individually muxed across different peripherals.
LANE0 of SERDES0 is muxed between USB and CPSW while LANE0 of SERDES1 is
muxed between PCIe and CPSW.
Define the lane-muxing macros to be used as the idle state values.

Update "k3-j722s.dtsi" to include "k3-am62p-j722s-common-{}".dtsi files in
order to reuse the nodes shared with AM62P. Also include the J722S specific
"k3-j722s-main.dtsi".
Since the J7 family of SoCs has the k3-{soc}.dtsi file organized as:
k3-{soc}.dtsi = CPU + Cache + CBASS-Ranges + "Peripheral-Includes"
switch the "k3-j722s.dtsi" file to the same convention.

Introduce the "k3-j722s-main.dtsi" file to contain main domain peripherals
that are specific to J722S SoC and are not shared with AM62P. The USB1
instance of the USB controller on J722S is different from that on AM62P.
Thus, add the USB1 node in "k3-j722s-main.dtsi".

The USB1 instance of USB controller on AM62P is different from the USB1
instance of USB controller on J722S. Thus, move the USB1 instance from
the shared "k3-am62p-j722s-common-main.dtsi" file to the AM62p specific
"k3-am62p-main.dtsi" file. Include "k3-am62p-main.dtsi" in "k3-am62p.dtsi".

The AM62P and J722S SoCs share most of the peripherals. With the aim of
reusing the existing k3-am62p-{mcu,main,thermal,wakeup}.dtsi files for
J722S SoC, rename them to indicate that they are shared with the J722S SoC.
The peripherals that are not shared will be moved in the upcoming patches
to the respective k3-{soc}-{mcu,main,wakeup}.dtsi files without "common" in
the filename, emphasizing that they are not shared.

The NAND expansion card plugs in over the HSE (High Speed Expansion)
connector. Add support for it.
We add the ranges property to the GPMC node instead of the NAND
overlay file to prevent below warnings.
/fragment@3/__overlay__: Relying on default #address-cells value
/fragment@3/__overlay__: Relying on default #size-cells value
As GPMC is dedicated for NAND use on this board, it should be OK.

A PRU system event "vring" has been added to each PRU and RTU
node in each of the ICSSG0, ICSSG1 and ICSSG2 remote processor
subsystems to enable the virtio/rpmsg communication between MPU
and that PRU/RTU core. The additions are done in the base
k3-am65-main.dtsi, and so are inherited by all the K3 AM65x
boards.
The PRU system events is the preferred approach over using TI
mailboxes, as it eliminates an external peripheral access from
the PRU/RTU-side, and keeps the interrupt generation internal to
the ICSSG. The difference from MPU would be minimal in using one
versus the other.
Mailboxes can still be used if desired, but currently there is
no support on firmware-side for K3 SoCs to use mailboxes. Either
approach would require that an appropriate firmware image is
loaded/booted on the PRU.

Add the bootph-all property to the memory node so that it can be
accessed by FDT functions at bootloader stage.
The bootloader requires the memory node to be able to initialize and set
the size of the DRAM banks. For this purpose, make sure all memory nodes
are present and standardized, and modify them if not.

The RS485 transceiver RE (Receiver enable) and DE (Driver enable) are
shorted and connected to both RTS/CTS of the SoC UART.
RE is active-low, DE is active-high.
Remove the "rs485-rts-active-low" flag to match RTS polarity with DE,
and fix communication in both transmit and receive directions.

For main_pktdma node, the TX Channel Realtime Register region 'tchanrt'
is 128KB and Ring Realtime Register region 'ringrt' is 2MB as shown in
memory map in the TRM[0] (Table 2-1).
So fix ranges for those register regions.

The CPSW9G instance of the CPSW Ethernet Switch supports USXGMII mode
with MAC Ports 1 and 2 of the instance, which are connected to ENET
Expansion 1 and ENET Expansion 2 slots on the EVM respectively, through
the Serdes2 instance of the SERDES.
Enable CPSW9G MAC Ports 1 and 2 in fixed-link configuration USXGMII mode
at 5 Gbps each.

J784S4 SoC has MAIN CPSW2G and CPSW9G instances of the CPSW
Ethernet Switch. CPSW2G has 1 external port and 1 host port
while CPSW9G has 8 external ports and 1 host port.
Add device-tree nodes for MAIN CPSW2G and CPSW9G and disable
them by default. MAIN CPSW2G will be enabled in the board file
while device-tree overlays will be used to enable CPSW9G.
