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] [1] https://gist.github.com/DhruvaG2000/6dcceb80cf7bbd1e624ec210532538cb Signed-off-by: Dhruva Gole <redacted> --- Changes in v3: - Sorted the #defines and structs for am62l as well after am62a - Pick the R-by tag from Kendall - Link to v2: https://lore.kernel.org/r/20260116-am62l-cpufreq-v2-0-eac7e2e78d29@ti.com (local) Changes in v2: - Sort alphabetically while adding AM62L as per Krzysztof's comments - Link to v1: https://lore.kernel.org/r/20260116-am62l-cpufreq-v1-0-63d062317ae9@ti.com (local) --- Dhruva Gole (3): cpufreq: dt-platdev: Add ti,am62l3 to blocklist cpufreq: ti-cpufreq: add support for AM62L3 SoC arm64: dts: ti: k3-am62l: support cpufreq arch/arm64/boot/dts/ti/k3-am62l-wakeup.dtsi | 5 +++ arch/arm64/boot/dts/ti/k3-am62l3.dtsi | 47 +++++++++++++++++++++++++++++ drivers/cpufreq/cpufreq-dt-platdev.c | 1 + drivers/cpufreq/ti-cpufreq.c | 34 ++++++++++++++++++++- 4 files changed, 86 insertions(+), 1 deletion(-) --- base-commit: 9b7977f9e39b7768c70c2aa497f04e7569fd3e00 change-id: 20260116-am62l-cpufreq-1987a04a6f68 Best regards, -- Dhruva Gole [off-list ref]
