Subject: [PATCH v2 0/6] Add initial support for QCS615 SoC and QCS615 RIDE
 board

This 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

This series are splited into three parts:
- 1-3: Binding files for QCS615 SoC and PDC (Reviewed)
- 4  : Soc table entry (Reviewed)
- 5-6: Initial DTSI and RIDE board device tree

Bindings Dependencies:

qfprom: https://lore.kernel.org/all/20240912-add_qfprom_compatible_for_qcs615-v1-1-9ef2e26c14ee@quicinc.com/
tcsr: https://lore.kernel.org/all/20240912-add_tcsr_compatible_for_qcs615-v1-1-5b85dd4d42ad@quicinc.com/

Build Dependencies:
tlmm: https://lore.kernel.org/all/20240910-add_qcs615_pinctrl_driver-v1-0-36f4c0d527d8@quicinc.com/

Patch made the following verifications:
- Successfully pass dt_binding_check with DT_CHECKER_FLAGS=-m for earch binding file
- Successfully pass dtbs_check with W=1 for dts
- Verified CPU Hotplug and online CPUs on QCS615 ride board
- Checked pinctrl-maps path
- Verified Watchdog functional with "echo 1 > /dev/watchdog", can trigger
  a watchdog bark and later bite
- Verified functional with DCC console function on QCS615 ride board
- RPMH controller driver probed successfully
- Sleep stats driver probed successfully and checked qcom_stats
  node on QCS615 ride board
