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 Bindings Dependencies: - watchdog: https://lore.kernel.org/all/20240920-add_watchdog_compatible_for_qcs615-v2-1-427944f1151e@xxxxxxxxxxx/ -
