Subject: [PATCH 0/2] thunderbolt: Disable CL states on older Titan Ridge firmware
Date: Tue, 24 Feb 2026 08:01:48 +0100 [thread overview]
Message-ID: <20260224070150.3320641-1-mika.westerberg@linux.intel.com> (raw)
Hi,
There is known issue on Titan Ridge with older firmware that makes the link
unstable if CL states are enabled. This series adds a quirk that disables
them for older NVM firmware.
Rene Sapiens (2):
thunderbolt: Read router NVM version before applying quirks
thunderbolt: Disable CLx on Titan Ridge-based devices with old firmware
