I will change it to firmware-name as this is the only type of firmware that this driver will need to load. There is no default name for the firmware. The name depends on the board being used. The current [1] possibilites are: am43x-evm-scale-data.bin am335x-bone-scale-data.bin am335x-evm-scale-data.bin Thank you, Drew [1] https://git.ti.com/cgit/processor-firmware/ti-amx3-cm3-pm-firmware/tree/bin?h=08.02.00.006 _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
