2025-09-16i3c: master: Add helpers for DMA mapping and bounce buffer handlingJarkko Nikula
Some I3C controllers such as MIPI I3C HCI may pad the last DWORD (32-bit) with stale data from the RX FIFO in DMA transfers if the receive length is not DWORD aligned and when the device DMA is IOMMU mapped. In such a case, a properly sized bounce buffer is required in order to avoid possible data corruption. In a review discussion, proposal was to have a common helpers in I3C core for DMA mapping and bounce buffer handling. Drivers may use the helper i3c_master_dma_map_single() to map a buffer for a DMA transfer. It internally allocates a bounce buffer if buffer is not DMA'able or when the driver requires it for a transfer. Helper i3c_master_dma_unmap_single() does the needed cleanups and data copying from the bounce buffer.

2025-09-16s390/dcssblk: Add DAX supportGerald Schaefer
With ZONE_DEVICE now available for s390, struct pages can be allocated for proper DAX support in dcssblk driver via devm_memremap_pages(). Adding struct pages for a range requires that the range is aligned to SUBSECTION_SIZE, which is defined as 2 MB in common code. Therefore, only enable DAX support and allocate struct pages for DCSS ranges that are aligned to 2 MB.

2025-09-16drm/display: bridge-connector: use scope-specific variable for the bridge ↵Luca Ceresoli
pointer Currently drm_bridge_connector_init() reuses the 'bridge' variable, first as a loop variable in the long drm_for_each_bridge_in_chain() and then in the HDMI-specific code as a shortcut to bridge_connector->bridge_cec. We are about to remove the 'bridge' loop variable for drm_for_each_bridge_in_chain() by moving to a scoped version of the same macro, which implies removing the 'bridge' variable from the main function scope. Additionally reusing the variable can make such long function less readable. Similarly to what commit 6f727c838ea8 ("drm/bridge-connector: Fix bridge in drm_connector_hdmi_audio_init()") already did for the audio HDMI bridge, use n local variable inside the scopes where it is needed as a bridge_connector->bridge_hdmi_cec shortcut to make its scope clearer as well as to allow removing the 'bridge' variable in an upcoming commit.
