Add the compatible string for the Qualcomm LeMans Draco EVK board (SA8775P/QCS9100 SoC). The compatible chain is: qcom,lemans-draco-evk qcom,lemans-draco-evk-som qcom,qcs9100 qcom,sa8775p Signed-off-by: Gopikishan Thawre <gthawre@qti.qualcomm.com>
Add build entry for the LeMans Draco EVK board DTB. Signed-off-by: Gopikishan Thawre <gthawre@qti.qualcomm.com>
Add device tree for the LeMans Draco EVK System-on-Module (SOM) based on the SA8775P/QCS9100 SoC. The SOM includes: - Complete RPMH regulator configuration for three pmm8654au PMICs: pmic-id a: smps4/5/9 and ldo4/5/6/7/8/9 pmic-id c: ldo1/2/3/4/5/6/7/8/9 pmic-id e: smps4/7/9 and ldo6/8 - Firmware paths for QUP firmware and remote processors (ADSP, CDSP0) - Debug UART (uart0) - XO board clock at 38.4 MHz, sleep clock at 32.768 kHz Signed-off-by: Gopikishan Thawre <gthawre@qti.qualcomm.com>

Add top-level board device tree and full board support for the Qualcomm
LeMans Draco EVK carrier board:
GPIO expanders on &i2c2 (carrier board, not SOM):
- Four 16-bit KTS1620EUAA-TR expanders (TCA6416-compatible) at
0x20–0x23 for camera/display MUX, PCIe/USB/DP MUX, camera OCP
power enables, and USB2/PCIe power enables.
- One 8-bit TCA9534APWR expander (PCA9534-compatible) at 0x38
(U445) for camera MCLK enables.
- EEPROM (giantec,gt24c256c) at 0x50 with MAC address nvmem layout.
- expander_int pinctrl state for TLMM gpio22 retained for future
interrupt wiring.
Peripheral nodes added to SOM DTSI:
- uart10 as geni-debug-uart (console)
- ufs_mem_hc / ufs_mem_phy with regulator assignments
- usb_0, usb_0_hsphy, usb_0_qmpphy, usb_2, usb_2_hsphy
- pmm8654au_2 GPIO states for USB interrupt and ID lines
- mmc1 alias corrected (was mmc0); serial0 → uart10, serial2 → uart0
Remove pcie0, pcie0_phy, pcie1, pcie1_phy, ethernet0 alias and
associated pinctrl states — PCIe and Ethernet not present on this
board variant.
Remoteproc SMMU stream IDs placed in lemans-draco-evk.dts
(board-specific IOMMU mappings, not SOM-generic):
adsp: SID 0x3000, mask 0x0
cdsp0: SID 0x21c0, mask 0x0400
cdsp1: SID 0x29c0, mask 0x0400
gpdsp0: SID 0x38a0, mask 0x0
gpdsp1: SID 0x38c0, mask 0x0

Fix GPIO expander nodes (compatible strings, I2C addresses, interrupt wiring),
add USB and UFS nodes with regulator assignments, and drop PCIe/Ethernet
nodes and their pinctrl states as they are not present on this board variant.
