George Moussalem 34d9172655 qualcommax: add ipq50xx target
Introduce support for the Qualcomm IPQ50xx SoC.
This series adds support for the following components:
- minimal boot support: GCC/pinctrl/watchdog/CPUFreq/SDI (upstreamed)
- USB2 (upstreamed)
- Thermal/Tsens
- PCIe gen2 1&2-lane PHY and controller
- PWM and PWM LED
- QPIC SPI NAND controller
- CMN PLL Block (provider of fixed rate clocks to GCC/ethernet/more.)
- Ethernet: IPQ5018 Internal GE PHY (1 gbps)
- Remoteproc MPD driver for IPQ5018 (2.4G) & QCN6122 (5/6G) Wifi

Subject: [PATCH] dt-bindings: firmware: qcom,scm: support indicating SDI
default state
IPQ5018 has SDI (Secure Debug Image) enabled by TZ by default, and that
means that WDT being asserted or just trying to reboot will hang the board
in the debug mode and only pulling the power and repowering will help.
Some IPQ4019 boards like Google WiFI have it enabled as well.
So, lets add a boolean property to indicate that SDI is enabled by default
and thus needs to be disabled by the kernel.
