Subject: [PATCH v2 0/3] cpufreq: ti: Add support for AM62L3 SoC

Hello,

This series adds CPU frequency scaling support for the TI AM62L3 SoC.

The AM62L3 is a low-power, low-cost SoC from Texas Instruments. This
series enables cpufreq support by:
1. Adding the SoC to the cpufreq-dt-platdev blocklist to prevent the generic driver from probing.
2. Extending the ti-cpufreq driver to support AM62L3 speed grading by reading the efuse.
3. Updating the device tree with the necessary operating points and clock configurations.

Tested on AM62L3 EVM [1]
