[PATCH 0/2] cpufreq: ti-cpufreq: Enable AM62A7 CPUFreq

[Vibhore Vardhan]

Hi,

This series adds cpufreq support for TI AM62A7 SoC.

AM62A7 has the same A53 and efuse configuration as AM625. Thus, soc_data
from AM625 is reused. This series adds compatible string for AM62A7 to
ti-cpufreq and cpufreq-dt-platdev drivers respectively.

Tested on am62a-sk board using manual frequency changes and then reading
back frequency with k3conf, and this shows matching frequency to what
was set. 

Link to the complete series including the DT patches:
https://github.com/DhruvaG2000/v-linux/commits/am62a_cpufreq_2023

Based on patch series for AM625 by Dave Gerlach.

Regards,
Vibhore

[PATCH 1/2] cpufreq: ti-cpufreq: Add support for AM62A7

[Vibhore Vardhan]

Add support for TI K3 AM62A7 SoC to read speed and revision values from
hardware and pass to OPP layer. AM62A7 has the same A53 and efuse 
configuration as AM625. Thus, soc_data from AM625 is reused.

Based on AM625 CPUFreq patch series by Dave Gerlach.

[PATCH 2/2] cpufreq: dt-platdev: Blacklist ti,am62a7 SoC

[Vibhore Vardhan]

Add ti,am62a7 SoC to the blacklist as the ti-cpufreq driver will handle
creating the cpufreq-dt platform device after it completes so it is not
created twice.
