[PATCH 0/5] soc: ti: add k3 platforms chipid module driver
From: Grygorii Strashko
Date: Thu Apr 23 2020 - 14:05:58 EST
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
