the non-addressable regions and include the rest of valid WKUP_PADCONFIG

wkup_pmx0 -> 13 pins (WKUP_PADCONFIG 0 - 12)
wkup_pmx1 -> 11 pins (WKUP_PADCONFIG 14 - 24)
wkup_pmx2 -> 72 pins (WKUP_PADCONFIG 26 - 97)

There are timer IO pads in the MCU domain, and in the MAIN domain. These
pads can be muxed for the related timers.
There are timer IO control registers for input and output. The registers
for CTRLMMR_TIMER*_CTRL and CTRLMMR_MCU_TIMER*_CTRL are used to control
the input. The registers for CTCTRLMMR_TIMERIO*_CTRL and
CTRLMMR_MCU_TIMERIO*_CTRL the output.
The multiplexing is documented in TRM "5.1.2.3.1.4 Timer IO Muxing Control
Registers" and "5.1.3.3.1.5 Timer IO Muxing Control Registers", and the
CASCADE_EN bit is documented in TRM "12.6.3.1 Timers Overview".
For chaining timers, the timer IO control registers also have a CASCADE_EN
input bit in the CTRLMMR_TIMER*_CTRL in the registers. The CASCADE_EN bit
muxes the previous timer output, or possibly and external TIMER_IO pad
source, to the input clock of the selected timer instance for odd numered
timers. For the even numbered timers, the CASCADE_EN bit does not do
anything. The timer cascade input routing options are shown in TRM
"Figure 12-3224. Timers Overview". For handling beyond multiplexing, the
driver support for timer cascading should be likely be handled via the
clock framework.
The MCU timer controls are also marked as reserved for
usage by the MCU firmware.

There are 20 general purpose timers on j721e that can be used for

The odd numbered timers have the option of being cascaded to even

As the binding for "current-speed" states, this should only be used
when the baud rate of an attached device cannot be detected. This is
the case for our attached on-board USB-to-UART converter used for
early kernel console. For all other unconnected/disabled ports this
can be configured in userspace later, DT is not the place for device
configuration, especially when there are already standard ways to
set serial baud in userspace.
Remove setting baud for all disabled serial ports and move setting
it for the couple enabled ports down into the board files.

MAIN_PLL0 has a flag set in DM (Device Manager) that removes it's
capability to re-initialise clock frequencies. CPTS and RGMII has
MAIN_PLL3 as their parent which does not have this flag. While RGMII
needs this reinitialisation to default frequency to be able to get
250MHz with its divider, CPTS can not get its required 200MHz with its
divider. Thus, move CPTS clock parent on J721S2 from MAIN_PLL3_HSDIV1 to
MAIN_PLL0_HSDIV6.
(Note: even GTC will be moved from MAIN_PLL3 to MAIN_PLL0 in U-Boot side
for the same reason)

Security Management Subsystem(SMS) has it's own unique secure
proxy as part of Security Accelerator (SA3) module. This is used
for communicating with ROM and for special usecases such as HSM
operations. In addition MCU island has it's own secure proxy for
usecases involving the MCU micro controllers. These are in addition
to the one in the main domain DMSS subsystem that is used for general
purpose communication.
Describe the nodes for use with bootloaders and firmware that require
these communication paths which uses interrupts to corresponding micro
controller interrupt controller. Mark the node as disabled since these
instances do not have interrupts routed to the main processor by
default for a complete description of the node.
