The Texas Instruments K3 Multicore SoC platforms have chipid module which
is represented by CTRLMMR_xxx_JTAGID register and contains information
about SoC id and revision.
Bits:
31-28 VARIANT Device variant
27-12 PARTNO Part number
11-1 MFG Indicates TI as manufacturer (0x17)
1 Always 1
This patch adds corresponding driver to identify the TI K3 SoC family and
revision, and registers 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().
Identification is done by:
- checking MFG to be TI ID
- retrieving Device variant (revision)
- retrieving Part number and convert it to the family
- retrieving machine from DT "/model"
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
