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 lets other drivers register SoC information after reading the JTAG ID through their own access path, and uses devm cleanup for registered SoC devices and their attributes. 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. Changelog: 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.
