As my understanding, we can go to Tegra_fan folder to modify fan setting, but now on our carrier board we can’t see this folder thus we can’t access this fan, so we also can’t modify our fan’s setting like PWM.
P.S. On our carrier board the 12V pin is OK because connect 12V fan can work, but we can’t control it.(PWM/ON & OFF switch)
Please kindly help us to resolve this issue, thanks.
I didn’t find vdd-fan-supply in tegra186-quill-power-tree-p3310-1000-a00-00.dtsi file. Did i need to add something in my code. Can you give me a sample ?
platform/t18x/common/kernel-dts/t18x-common-platforms/tegra186-quill-power-tree-p3310-1000-a00-00.dtsi
indicates there is a vdd-fan-supply field.
