[PATCH 0/3] soc: ti: Add TDA54 SCM configuration syscon support

From: Moteen Shah

Date: Mon Oct 19 2026 - 04:12:24 EST


This series adds support for the TDA54 SCM configuration region in the MCU
domain. The region is shared by several peripherals, so it is exposed as a
syscon regmap for other drivers to look up by phandle.

Patch 1 adds the device tree binding for ti,tda54-mcu-scm-conf.

Patch 2 splits the SoC decode and registration logic out of
k3_chipinfo_probe() into k3_socinfo_register() and exports it. The helper
ties the SoC device to the calling device with devm, so modular callers do
not need an unregister step. Other K3 drivers keep their current behaviour.

Patch 3 adds the TDA54 SCM configuration driver. It provides proxy-aware
register access with SCM unlock and claim handling, publishes the regmap
through syscon, and registers TDA54 SoC information through the helper from
patch 2. The option defaults to m on ARCH_K3.
