[sashiko-bot@kernel.org]

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [Low] Devicetree nodes within the `ahb` and `apb` buses are not sorted numerically by their unit addresses.
- [Low] Minor formatting and syntax style issues in node labels and properties.

arm64: dts: nuvoton: npcm845: Add peripheral nodes

Extend the NPCM845 SoC DTSI with the peripheral controller nodes needed
by the evaluation board and downstream platforms. This adds various 
controllers including Ethernet MACs, USB controllers, MMC, FIU, RNG, ADC, 
PWM/FAN, PSPI, I2C buses, and the OP-TEE firmware node.

[Severity: Low]
This isn't a bug, but should these FIU nodes in the ahb bus be sorted 
numerically by their unit addresses? It looks like spi@c0000000 is placed 
after spi@fb002000.

[Severity: Low]
This isn't a bug, but should this reg property use lowercase hex (0xc000) 
to match the unit address and standard Devicetree conventions?

[Severity: Low]
This isn't a bug, but the newly added I2C nodes (at 0xfff00000 and above) 
are grouped by peripheral type and placed before the PECI controller at 
0x100000. Does this arrangement skip the standard Devicetree coding 
style guideline to order nodes strictly by unit address?

[Severity: Low]
This isn't a bug, but is it possible to add the missing space after the colon 
in the node label (pwm_fan: pwm-fan-controller) and after the comma in the 
clock-names property ("pwm", "fan")?
