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 converts the SoC attributes, revision string, and registered SoC device in k3-socinfo to device-managed cleanup. Patch 3 splits the SoC decode and registration logic out of k3_chipinfo_probe() into k3_socinfo_register() and exports it, so drivers that read the JTAG ID through another access path can reuse the common K3 SoC identification logic. Patch 4 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 3. The option defaults to m on ARCH_K3. Changelog: Link to v2: https://lore.kernel.org/all/20261027083700.1964371-1-m-shah@ti.com/ Changes in v3: - Split the k3-socinfo device-managed cleanup changes from the exported SoC registration helper into separate patches. Link to v1: https://lore.kernel.org/all/20261019080736.944127-1-m-shah@ti.com/ Changes in v2: - No changes to the device tree binding patch. - Use devm-managed allocation for the SoC attributes and revision string in k3-socinfo, and simplify the cleanup of the registered SoC device. - Enable fast_io for the TDA54 SCM configuration regmap.
