NXP i.MX power-domain controllers (GPC, block control, SCU)

Controls on-chip power domains and block-level power gating in NXP's i.MX series of ARM application processors, covering the older GPC/GPCv2 controllers, i.MX8M block-control units, the newer i.MX93/i.MX9 block control, and the System Controller Unit power interface. These SoCs are widely used in industrial gateways, single-board computers, and edge AI devices.

recommendation

It should stay because it manages on-chip power domains for NXP's i.MX application processor family, including the i.MX8M, i.MX8M Plus, i.MX93, and newer i.MX9 parts that NXP still actively sells for industrial and edge devices in 2025. Bug fixes are still landing as recently as 2026, and there is no sign of upstream deprecation.

sources

  1. git.kernel.org

    A substantive 2026-04-01 upstream fix touched this directory: "pmdomain: imx8mp-blk-ctrl: Keep the NOC_HDCP clock enabled", indicating active maintenance rather than retirement.

  2. git.kernel.org

    Another recent bug fix in this directory, "pmdomain: imx: gpcv2: Fix the imx8mm gpu hang due to wrong adb400 reset", shows ongoing support for deployed i.MX8M hardware.

  3. nxp.com

    NXP lists the i.MX 8M Plus family as Active and positions it for industrial/edge applications, so hardware covered by these PM-domain drivers is still sold new.

  4. nxp.com

    NXP lists the i.MX 93 family as Active, with Linux-based edge/industrial positioning and longevity-program backing, confirming current-generation deployment relevance.

codex reasoning notes (technical)

Local shell inspection of drivers/pmdomain/imx/Kconfig and file list confirmed this is live kernel driver code for NXP i.MX PM domains, not helper data. Recent maintenance evidence came from local `git -c safe.directory=... log -- drivers/pmdomain/imx` output; commit URLs were then formed from the canonical stable kernel.org commit pattern (canonical recall). Current-market evidence came from web search results that opened NXP product pages for i.MX8M Plus and i.MX93. I found active fix traffic through 2026 and no concrete removal/deprecation signal in the checked evidence, so the correct disposition is keep.
