Subject: [PATCH v2 0/2] Add ADF4371 Reference Doubler and Reference Divider

This patch series add support for for reference doubler block and reference
divide by 2 clock block within the ADF4371.

The doubler is useful for increasing the PFD comparison frequency which will
result in a noise performance of the system.

The reference divide by 2 divides the reference signal by 2,
resulting in a 50% duty cycle PFD frequency.

Both features were requested from customers that purchased hundreds of adf4371
parts to use in their project. They need a way to adjust these blocks either
from userspace or devicetree.

The patch series aims to both satisfy the customer needs and be compliant with
the current kernel. The devicetree approach was chosen since these kind of
features are already present in the mainline kernel for parts such as adf4350.

  dt-bindings: iio: adf4371: add rdiv2 and doubler
  iio: frequency: adf4371: add ref doubler and div2
