Subject: [PATCH V3 20/21] dt-bindings: PCI: tegra194: Add monitor clock support
Date: Fri, 14 Oct 2022 00:08:53 +0530 [thread overview]
Message-ID: <20221013183854.21087-21-vidyas@nvidia.com> (raw)
In-Reply-To: <20221013183854.21087-1-vidyas@nvidia.com>
Tegra supports PCIe core clock monitoring for any rate changes that may be
happening because of the link speed changes. This is useful in tracking
any changes in the core clock that are not initiated by the software.
