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.

Example J721E:
  # cat /sys/devices/soc0/{machine,family,revision}
  Texas Instruments K3 J721E SoC
  J721E
  SR1.0

Example AM65x:
  # cat /sys/devices/soc0/{machine,family,revision}
  Texas Instruments AM654 Base Board
  AM65X
  SR1.0

Changes in v4:
 - convert to platform_driver as suggested by Arnd Bergmann <arnd@arndb.de>

Changes in v3:
 - add handling of kasprintf() fail

Changes in v2:
 - pr_debug() replaced with pr_info() to show SoC info on init
 - minor format change
 - split series on driver and platform changes
 - add Reviewed-by: Lokesh Vutla <lokeshvutla@ti.com>
