Hello, this is v3 of a series generalizing the driver of the ltc2497 (an i2c ADC) to be able to reuse most of the code for the ltc2496 (an spi variant of the ltc2497). Iteration v2 started with Message-Id: 20191114105159.14195-1-u.kleine-koenig@xxxxxxxxxxxxxx. The changes since v2 are based on feedback by Jonathan Cameron: - rename common file to ltc2497-core.c (from ltc249x.c), also don't use ltc249x in names for cpp symbols, functions and variables. - properly align spi and i2c transfer buffers for DMA maintenance - improve dt binding to mention spi specific properties Best regards Uwe Uwe Kleine-König (3): iio: adc: ltc2496: provide device tree binding document iio: adc: ltc2497: split protocol independent part in a separate module iio: adc: new driver to support Linear technology's ltc2496 .../bindings/iio/adc/lltc,ltc2496.yaml | 37 +++ MAINTAINERS | 2 +- drivers/iio/adc/Kconfig | 10 + drivers/iio/adc/Makefile | 3 +- drivers/iio/adc/ltc2496.c | 108 ++++++++ drivers/iio/adc/ltc2497-core.c | 243 ++++++++++++++++++ drivers/iio/adc/ltc2497.c | 234 ++--------------- drivers/iio/adc/ltc2497.h | 18 ++ 8 files changed, 445 insertions(+), 210 deletions(-) create mode 100644 Documentation/devicetree/bindings/iio/adc/lltc,ltc2496.yaml create mode 100644 drivers/iio/adc/ltc2496.c create mode 100644 drivers/iio/adc/ltc2497-core.c create mode 100644 drivers/iio/adc/ltc2497.h -- 2.24.0
