This patch series adds support for the Analog Devices ADF41513 and ADF41510
ultralow noise PLL frequency synthesizers. These devices are designed for
implementing local oscillators (LOs) in high-frequency applications.
The ADF41513 covers frequencies from 1 GHz to 26.5 GHz, while the ADF41510
operates from 1 GHz to 10 GHz.

Key features supported by this driver:
- Integer-N and fractional-N operation modes
- High maximum PFD frequency (250 MHz integer-N, 125 MHz fractional-N)
- 25-bit fixed modulus or 49-bit variable modulus fractional modes
- Digital lock detect functionality
- Phase resync capability for consistent output phase
- Load Enable vs Reference signal syncronization

The series includes:
1. PLL driver implementation
2. Device tree bindings documentation
3. IIO ABI documentation

Changes in v2:
- separate driver implementation from extra features and improve commit messages
- use macros from units.h
- explanation of custom parse function: adf41513_parse_uhz
- reorganize driver data structures
- drop clock framework support for now
- reorganize documentation
- Link to v1: https://lore.kernel.org/r/20251110-adf41513-iio-driver-v1-0-2df8be0fdc6e@analog.com
