This patch adds a reserved memory for the TI AM65X platform watchdog to reserve the specific info, triggering the watchdog reset in last boot, to know if the board reboot is due to a watchdog reset. Signed-off-by:

The J722S is a family of application processors built for Automotive and Linux Application development. J722S family of SoCs is a superset of the AM62P SoC family and shares similar memory map, thus the nodes are being reused from AM62P includes instead of duplicating the definitions. Some highlights of J722S SoC (in addition to AM62P SoC features) are: * Two Cortex-R5F for Functional Safety or general-purpose usage and two C7x floating point vector DSP with Matrix Multiply Accelerator for deep learning. * Vision Processing Accelerator (VPAC) with image signal processor and Depth and Motion Processing Accelerator (DMPAC). * 7xUARTs, 3xSPI, 5xI2C, 2xUSB2, 2xCAN-FD, 3xMMC and SD, GPMC for NAND/FPGA connection, OSPI memory controller, 5xMcASP for audio, 4xCSI-RX for Camera, 1 PCIe Gen3 controller, USB3.0 eCAP/eQEP, ePWM, among other peripherals. For those interested, more details about this SoC can be found in the Technical Reference Manual here: https://www.ti.com/lit/zip/sprujb3Co-developed-by: -

Main differences between the new variant and Advanced PG2: 1. Arduino interface is removed. Instead, an new ASIC is added for communicating with PLC 1200 signal modules. 2. USB 3.0 type A connector is removed, only USB 2.0 type A connector is available. 3. DP interface is removed. Instead, to communicate with PLC 1200 signal modules, a USB 3.0 type B connector is added but the signals are actually not USB. 4. DDR size is increased to 4 GB. 5. Two sensors are added, one tilt sensor and one light sensor. The light sensor it not yet added to the DT at this stage as it depends on to-be-added bindings. Co-developed-by:

There is a variant coming which does not support the Display Port. Move all related bits into a separate dtsi so that only those variants supporting the interface can include it. Along that, remove a redundant clock setting from k3-am65-iot2050-common-pg1.dtsi. Signed-off-by:

A new variant is to be added which will not have a arduino connector like the existing ones. Factor out all bits that are specific to this connector. The split is not perfect because wkup_gpio0 is defined based on what is common to all variants having the connector, thus containing also connector-unrelated information. But this is still cleaner than replicating this node into all 4 variants. Signed-off-by:

Set VDD_CORE minimum voltage to 0.75V, TI AM62 can run at either 0.75V or 0.85V depending on the actual speed grade and on the maximum configured speed (1.4GHz frequency requires 0.85V). The actual value is programmed into the PMIC EEPROM during manufacturing (according to the SOC speed grade) and this ensure that both the voltage values are valid and therefore the OS will not overwrite the value programmed into the PMIC.

The devices in the wkup domain are capable of waking up the system from suspend. We can configure the wkup domain devices in a generic way using the ti-sysc interconnect target module driver like we have done with the earlier TI SoCs. As ti-sysc manages the SYSCONFIG related registers independent of the child hardware device, the wake-up configuration is also set even if wkup_uart0 is reserved by sysfw. The wkup_uart0 device has interconnect target module register mapping like dra7 wkup uart. There is a 1 MB interconnect target range with one uart IP block in the target module. The power domain and clock affects the whole interconnect target module. Note we change the functional clock name to follow the ti-sysc binding and use "fck" instead of "fclk". Also note that we need to disable the target module reset as noted by Markus. Otherwise the sysfw using wkup_uart0 can get confused on some devices leading to boot time issues such as mbox timeouts.

Enable both SERDES and PCIe DT nodes in order to get PCIe working on the SERDES PCIe x2 personality card. The daughter card also has a USB 2.0 dual-role port. As the base board already supports a 2.0 dual-role port, enable the port on the SERDES card to be a host only port. This will prevent user confusion as having 2 ports in device mode often leads to confusion as to which port is bound to the gadget function driver. The PCIe x2 card is provided with the AM65x IDK configuration [1] so apply the overlay to k3-am654-idk.dtb [1] https://www.ti.com/lit/ug/spruim6a/spruim6a.pdfCo-developed-by:
