arm64: dts: ti: k3-j784s4: Fix wakeup pinmux range and pinctrl node offsets
The wkup_pmx register region in j784s4 has multiple non-addressable
regions, hence the existing wkup_pmx region is split as follows to
avoid the non-addressable regions. The pinctrl node offsets are
also corrected as per the newly split wkup_pmx* nodes.
wkup_pmx0 -> 13 pins (WKUP_PADCONFIG 0 - 12)
wkup_pmx1 -> 11 pins (WKUP_PADCONFIG 14 - 24)

MAIN_PLL0 has a flag set in DM (Device Manager) that removes it's

MAIN_PLL3 as their parent which does not have this flag. While RGMII
needs this reinitialisation to default frequency to be able to get

The J784S4 SoCs have 4 dual-core Arm Cortex-R5F processor (R5FSS)
subsystems/clusters. One R5F cluster (MCU_R5FSS0) is present within
the MCU domain, and the remaining three clusters are present in the
MAIN domain (MAIN_R5FSS0, MAIN_R5FSS1 & MAIN_R5FSS2). The functionality
of the R5FSS is same as the R5FSS functionality on earlier K3 platform
device J721S2. Each of the R5FSS can be configured at boot time to be
either run in a LockStep mode or in an Asymmetric Multi Processing (AMP)
fashion in Split-mode. These subsystems have 64 KB each Tightly-Coupled
Memory (TCM) internal memories for each core split between two banks -
ATCM and BTCM (further interleaved into two banks). There are some IP
integration differences from standard Arm R5 clusters such as the absence
of an ACP port, presence of an additional TI-specific Region Address
Translater (RAT) module for translating 32-bit CPU addresses into
larger system bus addresses etc.
Add the DT nodes for the R5F cluster/subsystems, the two R5F cores are
each added as child nodes to the corresponding cluster node. The clusters
are configured to run in LockStep mode by default, with the ATCMs enabled
to allow the R5 cores to execute code from DDR with boot-strapping code
from ATCM. The inter-processor communication between the main A72 cores
and these processors is achieved through shared memory and Mailboxes.
The following firmware names are used by default for these cores, and
can be overridden in a board dts file if needed:
MAIN R5FSS0 Core0: j784s4-main-r5f0_0-fw (both in LockStep and Split modes)

arm64: dts: ti: k3-am62a: Add general purpose timers
Similar to commit
3308a31c507c ("arm64: dts: ti: k3-am62: Add general
purpose timers for am62"), there are 12 general purpose timers on am62a7
split between 8 in main and 4 in mcu domains. The 4 in mcu domain do not
have interrupts that are routable to a53.
We configure the timers with the 25 MHz input clock by default as the
32.768 kHz clock may not be wired on the device. We leave the MCU domain
timers clock mux unconfigured, and mark the MCU domain timers reserved.
The MCU domain timers are likely reserved by the software for the ESM
module.

Drop bootargs from the dts. The console arguments are already covered in
stdout-path property and earlycon is a debug property that should be
