Introduces the Device Tree for the QCS615 platform.
Features added and enabled:
- CPUs with PSCI idle states
- Interrupt-controller with PDC wakeup support
- Timers, TCSR Clock Controllers
- Reserved Shared memory
- QFPROM
- TLMM
- Watchdog
- RPMH controller
- Sleep stats driver
- Rpmhpd power controller
- Interconnect
- GCC and Rpmhcc
- QUP with Uart serial support
Bindings and base Device Tree for the QCS615 SoC are splited
in four parts:
- 1-2: Binding files for QCS615 SoC and PDC (Reviewed)
- 3-4: Initial DTSI and RIDE board device tree
- 5 : Enable uart related configs
