TI DRA7 / Jacinto 6 IODelay pin controller
A pin-multiplexing and IO-delay configuration block found on Texas Instruments' DRA7 / Jacinto 6 SoCs, a family of automotive infotainment and industrial application processors that TI has shipped since the mid-2010s and still sells in 2025. It fine-tunes signal timing on the chip's external pins so that interfaces like Ethernet and memory buses meet their electrical requirements.
recommendation
Worth keeping but worth labelling as legacy DRA7-specific hardware. The chip family it serves (TI's Jacinto 6 / DRA7 automotive and embedded SoCs) is niche today but TI still lists parts like the DRA724 as active products in 2025, and the code received real bug-fix and cleanup backports as recently as October 2024. That ongoing maintenance and continued availability of the silicon make removal premature, but a note that this is a single-SoC-family driver would help future readers.

Upstream Kconfig describes this as the TI IODelay Module pinconf driver and limits it to the DRA7 SoC family.
- git.kernel.org
The driver matches compatible string "ti,dra7-iodelay", confirming it targets DRA7-family hardware rather than a generic abstraction.
- lore.kernel.org
The driver received a real bug-fix backport in October 2024 ("Fix some error handling paths"), indicating ongoing maintenance rather than abandonment.
- lore.kernel.org
The driver also received cleanup work in October 2024 ("Use scope based of_node_put() cleanups"), reinforcing continued upstream attention.
- ti.com
TI listed a DRA7-family SoC product page as ACTIVE, supporting that at least some supported hardware was still sold new through 2025.
codex reasoning notes (technical)
Real driver, not an asset/helper dir. Local shell inspection of Kconfig and source identified this as the DRA7-only TI IODelay pinconf driver (compatible: ti,dra7-iodelay). lore_file_timeline on drivers/pinctrl/ti/pinctrl-ti-iodelay.c showed fresh 2024 traffic; cited lore URLs came from that MCP result and are maintenance/backport patches, not removal discussion. Web search found TI's DRA724 product page marked ACTIVE, so hardware is still commercially available but limited to older automotive/embedded DRA7 deployments. That makes present-day use niche/low-volume, but active enough to keep rather than deprecate; annotate as legacy DRA7-specific hardware.
