Texas Instruments K3 Display Subsystem (TIDSS)

Drives the on-chip display subsystem in Texas Instruments' K3/Keystone-family SoCs, including the AM625, AM62A, AM62L, AM65x, and J721e/DRA829 parts used in industrial HMIs, automotive infotainment, and the BeagleBone-class single-board computers shipping today.

recommendation

It should stay in the kernel because it is the only driver for the display block found in TI's current K3-family SoCs (AM625, AM62A, AM62L, AM65x, J721e/DRA829 and friends), all of which TI still markets as active products in 2025. Upstream activity is healthy, with maintenance patches and new-SoC enablement (such as AM62P support) landing as recently as 2026.

sources

  1. lore.kernel.org

    TIDSS received upstream maintenance work in April 2026, showing the driver is active rather than abandoned.

  2. lore.kernel.org

    A 2026 patch adds AM62P display-subsystem support to drm/tidss, indicating ongoing enablement for new TI SoCs.

  3. ti.com

    TI lists AM625 as ACTIVE and describes its display subsystem, confirming current-market silicon using this driver family.

  4. ti.com

    TI lists DRA829V as ACTIVE; this J721E-family SoC has display outputs covered by the TIDSS-compatible set in the driver.

codex reasoning notes (technical)

Local `exec_command` on the source tree showed compat strings for ti,k2g-dss, ti,am625-dss, ti,am62a7-dss, ti,am62l-dss, ti,am65x-dss, and ti,j721e-dss, identifying the hardware family as TI DSS/TIDSS. `lore_file_timeline` on drivers/gpu/drm/tidss/tidss_drv.c returned fresh 2026 patches and no removal pattern; cited lore URLs came from that tool. TI product URLs were obtained via `web.search_query` and show AM625 and DRA829V marked ACTIVE, so hardware is still sold new in 2025-era catalogs. Because the driver is seeing current upstream maintenance plus new-SoC enablement, and there is no generic replacement for this SoC-specific display block, the right disposition is keep.
