The binding for this clock controller requires that clock-names are
present. They're not really used by the kernel driver, but they're
marked as required, so someone might have assumed it's done on purpose
(where in reality we try to stay away from that since index-based
references are faster, take up less space and are already widely used)
and referenced it in drivers for another OS.
Hence, do the least painful thing and add the missing entries.

The 'cpu-supply' properties in the IPQ9574 SoC dtsi are referencing to
a regulator provided by an MP5496 PMIC via the RPM firmware which's node
is defined externally in the common RDP dtsi file.
Since the PMIC is not part of the SoC it should not be referenced from
the SoC specific dtsi, so remove the properties from there and define
those in the common RDP dtsi instead.
While at it, also change the prefix of the label from 'ipq9574' to
'mp5496' to keep it consistent with the labels of the l{2,5} regulators
provided by the same PMIC.
No functional changes. According to dtx_diff there are no differences
between the ipq9574*.dtb files built with and without the change.

GCC_PCIE_CLKREF_EN controls a repeater that provides the reference clock
only to the PCIe0 PHY. PCIe1 PHY receives its refclk directly from the CXO
source.
If the PCIe1 driver in HLOS votes for or against GCC_PCIE_CLKREF_EN, it
will inadvertently modify the refclk to PCIe0 as well. Since PCIe0 is
managed by WPSS while PCIe1 is managed in HLOS, there is no mechanism to
coordinate these votes. As a result, HLOS may disable this repeater
during suspend and cut off the PCIe0 PHY refclk while PCIe0 is still
active.
Replace the unused GCC_PCIE_CLKREF_EN clock entry with RPMH_CXO_CLK to
reflect the actual hardware wiring and prevent unintended changes to
PCIe0 clocking.

The PURWA-IOT-EVK is an evaluation platform for IoT products, composed of
the Purwa IoT SoM and a carrier board. Together, they form a complete
embedded system capable of booting to UART.
PURWA-IOT-EVK uses the PS8833 as a retimer for USB0, unlike HAMOA-IOT-EVK.
Meanwhile, USB0 bypasses the SBU selector FSUSB42.
Make the following peripherals on the carrier board enabled:
- UART
- On-board regulators
- USB Type-C mux
- Pinctrl
- Embedded USB (EUSB) repeaters
- NVMe
- pmic-glink
- USB DisplayPorts
- Bluetooth
- WLAN
- Audio
- PCIe ports for PCIe3 through PCIe6a
- TPM

The PURWA-IOT-SOM is a compact computing module that integrates a System
on Chip (SoC) — specifically the x1p42100 — along with essential
components optimized for IoT applications. It is designed to be mounted on
carrier boards, enabling the development of complete embedded systems.
Purwa uses a slightly different Iris HW revision (8.1.2 on Hamoa, 8.1.11 on
Purwa). Support will be added later.
Make the following peripherals on the SOM enabled:
- Regulators on the SOM
- Reserved memory regions
- PCIe3, PCIe4, PCIe5, PCIe6a
- USB0 through USB6 and their PHYs
- ADSP, CDSP
- Graphic
