Add support for SYSTEM_RESET2 vendor-specific resets as reboot-modes in the psci node. Describe the resets: "bootloader" will cause device to reboot and stop in the bootloader's fastboot mode. "edl" will cause device to reboot into "emergency download mode", which permits loading images via the Firehose protocol.

All the Lemans IOT variants boards are using Gunyah hypervisor which means that, so far, Linux-based OS could only boot in EL1 on those devices. However, it is possible for us to boot Linux at EL2 on these devices [1]. When running under Gunyah, the remote processor firmware IOMMU streams are controlled by Gunyah. However, without Gunyah, the IOMMU is managed by the consumer of this DeviceTree. Therefore, describe the firmware streams for each remote processor. Add a EL2-specific DT overlay and apply it to Lemans IOT variant devices to create -el2.dtb for each of them alongside "normal" dtb.

There's a WCN6855 WiFi/Bluetooth module on an M.2 card. To make Bluetooth work, we need to define the necessary device tree nodes, including UART configuration and power supplies. Since there is no standard M.2 binding in the device tree at present, the PMU is described using dedicated PMU nodes to represent the internal regulators required by the module. The module provides a 3.3V supply, which originates from the main board’s 12V rail. To represent this power hierarchy in the device tree, add a fixed 12V regulator node as the DC-IN source and link it to the 3.3V regulator node.

…bypass pwrseq flow There is a conflict between the current DTS configuration and the driver behavior for the WCN6855 Bluetooth path. With the PMU node in place, the driver takes the pwrseq code path unintentionally, which leads to Bluetooth failing to power up during an on -> off -> on transition. To unblock function, temporarily remove the WCN6855 PMU node so that the driver follows the non-pwrseq path and avoids the unexpected sequence. This is a TEMPORARY WORKAROUND. Once a proper M.2 binding/solution is upstreamed, will re-submit both DTS and driver changes aligned with the M.2 model. Signed-off-by: Wei Deng <[email protected]>
