Add compatible strings for the Qualcomm LeMans Draco EVK board based on the SA8775P/QCS9100 SoC. Signed-off-by: Gopikishan Thawre <gthawre@qti.qualcomm.com> (cherry picked from commit 9736e78)
Add build entries for lemans-draco-evk.dtb and lemans-draco-evk-el2.dtb. Signed-off-by: Gopikishan Thawre <gthawre@qti.qualcomm.com>
Add the SOM device tree for the SA8775P/QCS9100-based LeMans Draco EVK with RPMH regulators for three pmm8654au PMICs, QUP/remoteproc firmware paths, debug UART, and board clocks. Signed-off-by: Gopikishan Thawre <gthawre@qti.qualcomm.com> (cherry picked from commit 8db5519)
Add the top-level board DTS and extend the SOM DTSI with carrier board peripherals: I2C GPIO expanders, EEPROM with MAC address layout, UFS, USB, uart10 as console, and remoteproc SMMU stream IDs. Remove pcie0, pcie1 and ethernet0 absent on this board. Signed-off-by: Gopikishan Thawre <gthawre@qti.qualcomm.com> (cherry picked from commit d5c1ee4)
lemans-draco-evk-som.dtsi inlines the Lemans EL2-hosting device-tree modifications normally applied via the lemans-el2.dtbo overlay, but missed the video-firmware child node under &iris that the overlay also provides. Without this node, IRIS has no fw_dev, so it takes the firmware-load path meant for boards with an external hypervisor managing the SHM bridge. Since Draco hosts EL2 in Linux itself, TrustZone rejects the un-bridged firmware buffer with -EINVAL, and IRIS firmware load fails. Add the missing video-firmware iommu node (same SID as lemans-el2.dtso) so firmware loading uses the correct self-managed TZMem path on Draco.

arm64: dts: qcom: lemans-draco-evk: add video-firmware iommu node
Add the missing video-firmware iommu node (same SID as
lemans-el2.dtso) so firmware loading uses the correct self-managed
TZMem path on Draco.
