Subject: [PATCH 0/3] i2c: octeon/thunderx: Fix DMA mask + improvements
Date: Wed, 4 Nov 2026 11:49:09 +0100 [thread overview]
Message-ID: <20261104104912.166301-1-paul.cercueil@bootlin.com> (raw)
Hi Robert, Andi,
This patchset adds a fix to the ThunderX driver where the DMA mask was
not set, sometimes preventing MSI-X from being initialized properly.
The first patch improves error handling on the bus, and the third patch
improves the latency in HS mode.
Cheers,
-Paul
