I wrote a simple driver to access FPGA's memory. As you can see from lspci output below, 32KB memory mapped to Region 4 (BAR4) and I use … Web6 apr. 2024 · The regmap API supports IO port accessors so we can take advantage of regmap abstractions rather than handling access to the device registers directly in the driver. In addition, to improve code organization in stx104_probe (), the devm_iio_device_register () call is moved above GPIO configuration in order to keep relevant code closer together.
