The board provides UFS and microSD storage, two M.2 M-key slots, an M.2 E-key slot, a QPS615/TC9563 PCIe switch, USB Type-C ports with DisplayPort alternate mode, USB Type-A ports, HDMI 2.1 output, headset audio and a 40-pin expansion header. This series adds the initial device tree support for the board. It describes the regulators, storage, PCIe topology, USB and display outputs, audio, remote processors, thermal sensors, RTC, EEPROM and expansion header. Build targets for both the regular and EL2 device trees are included. The TC9563 power-control driver powers off external downstream ports whose device tree nodes have status = "disabled". On the Dragon Q8B, config-space reads to these powered-off port functions raise an Arm SError instead of returning an all-ones PCI error response, preventing the board from completing boot. The PCI OF change to skip config-space reads for unavailable DT-described bridge functions has been split out into a separate two-patch series for the PCI tree. Disabled endpoint functions remain discoverable so PCI fixups can still be applied, while driver binding continues to be suppressed later. The onboard HDMI output is provided by a Chrontel CH7218A DisplayPort 1.4 to HDMI 2.1 protocol converter. The device boots its firmware from on-chip flash and requires no host-side configuration. The PCIe ECAM and 64-bit memory windows are defined in the shared SC8280XP DTSI for all five controllers. The board DTS inherits these SoC resources. The SA8540P PCIe2a and PCIe3a address maps are kept unchanged. The series also documents the board compatible. The SC8280XP TLMM binding change allowing gpio-line-names has already been applied and is no longer included in this series. The PCI change is required before applying the board DTS patch; otherwise the disabled TC9563 downstream ports cause a boot-time SError.
