Colin Ian King	59dba8facb	iio: adc: adc12138: make array ch_to_mux static, makes object code smaller ... Don't populate const array ch_to_mux on the stack, instead make it static. Makes the object code smaller by over 200 bytes: Before: text data bss dec hex filename 12663 1648 128 14439 3867 drivers/iio/adc/ti-adc12138.o After text data bss dec hex filename 12353 1744 128 14225 3791 drivers/iio/adc/ti-adc12138.o (gcc version 7.2.0 x86_64) Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>	2017-10-21 17:56:09 +01:00
Jonathan Cameron	52b31bcc93	iio:adc: drop assign iio_info.driver_module and iio_trigger_ops.owner ... The equivalent of both of these are now done via macro magic when the relevant register calls are made. The actual structure elements will shortly go away.

Akinobu Mita	50a6edb1b6	iio: adc: add ADC12130/ADC12132/ADC12138 ADC driver ... This adds Texas Instruments' ADC12130/ADC12132/ADC12138 12-bit plus sign ADC driver. I have tested with the ADC12138. The ADC12130 and ADC12132 are not tested but these are similar to ADC12138 except that the mode programming instruction is a bit different.
