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.

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 <wei.deng@oss.qualcomm.com>

…er in host mode
Enable secondary USB controller in host mode on lemans EVK Platform.
Secondary USB controller is connected to a Genesys Logic USB HUB GL3590
having 4 ports. The ports of hub that are present on lemans EVK standalone
board are used as follows:-
1) port-1 is connected to HD3SS3220 Type-C port controller.
2) port-4 is used for the M.2 E key on corekit. Standard core kit uses UART
for Bluetooth. This port is to be used only if user optionally replaces the
WiFi card with the NFA765 chip which uses USB for Bluetooth.
Remaining 2 ports will become functional when the interface plus mezzanine
board is stacked on top of corekit:
3) port-2 is connected to another hub which is present on the mezz through
which 4 type-A ports are connected.
4) port-3 is used for the M.2 B key for a 5G card when the mezz is
connected.

Hence, describe the connector node and link it with the PCIe 0 Root Port and UART17 nodes through graph port/endpoint.

Both regulators are always-on and are required by the pcie-m2-e-connector binding.

The ADSP PAS on several Qualcomm SoCs (e.g. SA8775P/lemans, QCS8300, Monaco) needs more than a single SMMU stream ID for the audio ML (machine-learning) offload use case. In addition to the primary ADSP stream ID, the DSP/SPF issues DMA transactions through extra stream IDs that are not covered by the existing single-entry mapping. Relax the iommus constraint to allow between 1 and 3 entries so the additional ML offload stream IDs can be described, fixing dtb_check schema violations on device trees that add them.

…d SMMU mappings The audio ML (machine-learning) offload use case requires a contiguous, physically addressable buffer shared with the audio DSP/SPF, and issues DMA transactions through additional SMMU stream IDs that are not covered by the existing ADSP mapping. Add a dedicated reusable shared-dma-pool CMA region (16 MiB, 4 MiB aligned) and wire it to the q6apm DAIs node via memory-region. A dedicated pool guarantees the alignment and contiguity the DSP expects and isolates these allocations from the default CMA region. Under the EL2 (Gunyah/hypervisor) configuration the SMMU is fully enforcing, so the ML transactions are otherwise blocked and faulted: arm-smmu 15000000.iommu: Blocked unknown Stream ID 0x3060 arm-smmu 15000000.iommu: Blocked unknown Stream ID 0x3062 Add the ML-related stream IDs (0x3060 mask 0x9, 0x3062 mask 0x1) to the remoteproc_adsp iommus property in the EL2 overlay so these buffers are translated by the SMMU instead of being rejected.

The Iris VPU has separate streams with different IOVA constraints. The non-pixel stream must be limited to the 0-600 MB IOVA range, while the pixel stream can use the full IOVA space. Using a single set of IOMMU entries for the Iris node does not describe these per-stream limits and can allow accesses outside the supported range, which may lead to device crashes. One such issue was reported at: https://gitlab.freedesktop.org/drm/msm/-/work_items/100 Add non-pixel and pixel child nodes, move each stream ID to its corresponding child node, and add a reserved IOVA range for the non-pixel stream.
