Using the ratios, there was no way to represent "disabled" (i.e. infinity). Based on the bmp280 driver I went with using the power coefficients (e.g. 1, 2, 4, 8, ...) where 1 is disabled (n=0). v1 -> v2: - Break into individual patches v1: - Initial patch to enable IIR and thermocouple-type - Recognize mcp9601 Ben Collins (6): dt-bindings: iio: mcp9600: Set default 3 for thermocouple-type dt-bindings: iio: mcp9600: Add microchip,mcp9601 and add constraints iio: mcp9600: White space and fixed width cleanup iio: mcp9600: Recognize chip id for mcp9601 iio: mcp9600: Add support for thermocouple-type iio: mcp9600: Add support for IIR filter .../iio/temperature/microchip,mcp9600.yaml | 61 +++- drivers/iio/temperature/Kconfig | 8 +- drivers/iio/temperature/mcp9600.c | 295 +++++++++++++++++- 3 files changed, 341 insertions(+), 23 deletions(-) -- 2.39.5
