Subject: [PATCH v2 0/4] i2c: octeon/thunderx: Fix DMA mask + improvements
Date: Fri, 13 Nov 2026 14:41:24 +0100 [thread overview]
Message-ID: <20261113134128.58826-1-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 v2 brings an extra patch that fixes an infinite loop in the clock
divisor calculation.
The other two patches improve error handling on the bus, and the latency
in HS mode.
Cheers,
-Paul
Changelog:
v2:
- [1/4]: New patch
- Every other patch untouched.
Tanmay Jagdale (4):
i2c: octeon: Fix infinite loop in clock divisor calculation
i2c: octeon: Add error state recovery
i2c: thunderx: Set DMA mask
i2c: thunderx: Use polling with delay in HS mode
