From 09d1855656dad04127aee195baf2eedae029175d Mon Sep 17 00:00:00 2001 From: Alex Helms Date: Mon, 12 Sep 2022 11:36:12 -0700 Subject: dt-bindings: Renesas versaclock7 device tree bindings Renesas Versaclock7 is a family of configurable clock generator ICs with fractional and integer dividers. This driver has basic support for the RC21008A device, a clock synthesizer with a crystal input and 8 outputs. The supports changing the FOD and IOD rates, and each output can be gated.
