Subject: [PATCH 3/4] phy: cadence-torrent: Add PCIe + DP multilink configuration for 100MHz refclk
Date: Thu, 27 Jan 2022 15:29:57 +0100	[thread overview]
Message-ID: <20220127142958.23465-4-sjakhade@cadence.com> (raw)
In-Reply-To: <20220127142958.23465-1-sjakhade@cadence.com>

Add multilink DP configuration support for 100MHz reference clock rate.
This is the only clock rate supported currently for multilink PHY
configurations. Also, add PCIe + DP multiprotocol multilink register
configuration sequences for 100MHz refclk with no SSC.
