Hi All, This series introduces TI K3 Multicore SoC platforms chipid module driver which provides identification support of the TI K3 SoCs (family, revision) and register this information with the SoC bus. It is available under /sys/devices/soc0/ for user space, and can be checked, where needed, in Kernel using soc_device_match(). It is also required for introducing support for new revisions of K3 AM65x/J721E SoCs.
