The board uses lane 1 of SERDES for USB. Set the mux accordingly. The USB controller and EVM supports super-speed for USB0 on the Type-C port. However, the SERDES has a limitation that up to 2 protocols can be used at a time. The SERDES is wired for PCIe, eDP and USB super-speed. It has been chosen to use PCIe and eDP as default. So restrict USB0 to high-speed mode. Signed-off-by:

Reserve memory for remote processors. Two memory regions are reserved for each remote processor. The first 1Mb region is used for virtio Vring buffers for IPC and the second region is used for holding resource table, trace buffer and as external memory to the remote processor. The mailboxes are also assigned for each remote processor. Signed-off-by:

The J784S4 SoCs have four TMS320C71x DSP subsystems in the MAIN voltage domain. The functionality of these DSP subsystems is similar to the C71x DSP subsystems on earlier k3 device J721S2. Each subsystem has a 48 KB of L1D configurable SRAM/Cache and 512 KB of L2 SRAM/Cache. This subsystem has a CMMU but is not currently used. The inter-processor communication between the main A72 cores and the C71x DSPs is achieved through shared memory and mailboxes. Add the DT nodes for these DSP processor sub-systems. Signed-off-by:

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) MAIN R5FSS0 Core1: j784s4-main-r5f0_1-fw (needed only in Split mode) MAIN R5FSS1 Core0: j784s4-main-r5f1_0-fw (both in LockStep and Split modes) MAIN R5FSS1 Core1: j784s4-main-r5f1_1-fw (needed only in Split mode) MAIN R5FSS2 Core0: j784s4-main-r5f2_0-fw (both in LockStep and Split modes) MAIN R5FSS2 Core1: j784s4-main-r5f2_1-fw (needed only in Split mode) MCU R5FSS0 Core0: j784s4-mcu-r5f0_0-fw (needed only in Split mode) MCU R5FSS0 Core1: j784s4-mcu-r5f0_1-fw (needed only in Split mode) Signed-off-by:

wkup_pmx splits into multiple regions. Like wkup_pmx0 -> 13 pins (WKUP_PADCONFIG 0 - 12) wkup_pmx1 -> 2 pins (WKUP_PADCONFIG 14 - 15) wkup_pmx2 -> 59 pins (WKUP_PADCONFIG 26 - 84) wkup_pmx3 -> 8 pins (WKUP_PADCONFIG 93 - 100) With this split, pin offset needs to be adjusted to match with new pmx for all pins above wkup_pmx0. Example a pin under wkup_pmx1 should start from 0 instead of old offset(0x38 WKUP_PADCONFIG 14 offset) J7200 Datasheet (Table 6-106, Section 6.4 Pin Multiplexing) : https://www.ti.com/lit/ds/symlink/dra821u.pdf Fixes: 9ae21ac4 ("arm64: dts: ti: k3-j7200: Fix wakeup pinmux range") Signed-off-by:Keerthy <j-keerthy@ti.com> Signed-off-by:

Similar to commit 3308a31c ("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. Signed-off-by:

Drop bootargs and add aliases based on base pinout of SK as per [1] and evm per [2]. Indices chosen attempt to maintain some level of consistency with existing aliases. While at this, drop a extra EoL. While this patch could be split, it seems trivial to add additional cleanup steps.
