Yes, that sounds like the best approach. What were your thoughts on enabling the second CPU: line just to display the temperature grade if CONFIG_IMX6_THERMAL was not enabled?
I'm surprised someone on this list hasn't already tested this on IMX6SX.
Fabio - certainly you must have a reference board with an IMX6SX and could enable/test that the CPU markings agree with what is detected/displayed via OTP?
Yes, I do have a mx6sx sdb board, but the one I have is from the old silicon and I had issues event with the temperature reading, so I prefer not to rely on my testing.
Ye Li / Peng / Nitin,
Could some of you please test Tim's series on a mx6sx sdb and let us know what it displays on the CPU lines?
Tested on mx6sx sdb Revb board. I applied the following patches for this test:
mx6: add OTP bank1 registers thermal: imx_thermal: use CPU temperature grade for trip points imx: mx6: add display of CPU temperature grade in print_cpuinfo() imx: mx6: add get_cpu_temp_grade to obtain cpu temperature grade from OTP mx: mx6: display max cpu frequency in print_cpuinfo() imx: mx6: add get_cpu_speed_grade_hz func to return MHz speed grade from OTP
The log info: " U-Boot 2015.07-rc1-00256-gec154cc (May 18 2015 - 09:00:57)
