Subject: [PATCH v2 0/4] i3c: mipi-i3c-hci: Make able to work with IOMMU enabled
Date: Fri, 15 Aug 2025 17:12:38 +0300	[thread overview]
Message-ID: <20250815141242.2013767-1-jarkko.nikula@linux.intel.com> (raw)

Hi

Here's the 2nd version of common I3C core DMA mapping and bounce buffering
handling and making the MIPI I3C HCI able to work with IOMMU enabled.

Changes to the v1:
- DMA mapping length is also cache_line_size() aligned in order to avoid
  possible double bouncing from the SWIOTLB.
- Using DEFINE_FREE and __free infra for cleanup and changes to the other
  patches accordingly.
- Added more description to the patch 1/4 commit log and slight corrections
  to others.

Jarkko Nikula (4):
  i3c: master: Add helpers for DMA mapping and bounce buffer handling
  i3c: mipi-i3c-hci: Use core helpers for DMA mapping and bounce
    buffering
  i3c: mipi-i3c-hci: Use physical device pointer with DMA API
  i3c: mipi-i3c-hci: Use own DMA bounce buffer management for I2C
    transfers
