From 3a6ba7dc7799355557938fbdc15a558236011429 Mon Sep 17 00:00:00 2001 From: Vincent Cheng Date: Thu, 31 Oct 2019 23:20:07 -0400 Subject: ptp: Add a ptp clock driver for IDT ClockMatrix. The IDT ClockMatrix (TM) family includes integrated devices that provide eight PLL channels. Each PLL channel can be independently configured as a frequency synthesizer, jitter attenuator, digitally controlled oscillator (DCO), or a digital phase lock loop (DPLL). Typically these devices are used as timing references and clock sources for PTP applications. This patch adds support for the device.
