iio: adc: twl4030: Fold twl4030-madc.h into driver

2017-06-11T14:07:33Z

twl4030-madc.h is no longer used by anything outside of the iio driver, so it can be merged into the driver. Signed-off-by: Sebastian Reichel Acked-by: Wolfram Sang Signed-off-by: Jonathan Cameron

iio: adc: twl4030: Remove twl4030_madc_request.func_cb

2017-06-11T14:07:32Z

This functionality is not used by the IIO subsystem. Due to removal of legacy API it can also be removed. Signed-off-by: Sebastian Reichel Acked-by: Wolfram Sang Signed-off-by: Jonathan Cameron

iio: adc: twl4030: Drop struct twl4030_madc_user_parms

2017-06-11T14:07:32Z

This struct is no longer used by anything in the kernel. Signed-off-by: Sebastian Reichel Acked-by: Wolfram Sang Signed-off-by: Jonathan Cameron

iio: adc: twl4030: Unexport twl4030_madc_conversion()

2017-06-11T14:07:31Z

All madc users have been converted to IIO API, so drop the legacy API. The function is still used inside of the driver. Signed-off-by: Sebastian Reichel Acked-by: Wolfram Sang Signed-off-by: Jonathan Cameron

iio: adc: twl4030: Drop twl4030_get_madc_conversion()

2017-06-11T14:07:30Z

Drop legacy twl4030_get_madc_conversion() method. It has been used by drivers to get madc data before it conversion to IIO API. There are no users in the mainline kernel anymore. Signed-off-by: Sebastian Reichel Acked-by: Wolfram Sang Signed-off-by: Jonathan Cameron

mfd: twl4030-madc: Add support for raw value in twl4030_madc_conversion

2013-04-08T14:36:23Z

Driver twl4030-madc has hardcoded channel types (10 - battery current, 1 - battery temperature) and also conversation data in variable twl4030_divider_ratios. These hardcoded channels are incorrect for Nokia RX-51 board (where is channel 0 - battery temperature). For Nokia RX-51 there is rx51_battery power_supply driver which reporting battery information via twl4030_madc_conversion. But this driver needs raw values (not converted via some hardcoded functions). So this patch adding new parameter "raw" to struct twl4030_madc_request which tell twl4030-madc driver to not convert values, but rather return raw.

mfd: Turn on the twl4030-madc MADC clock

2011-10-24T12:09:10Z

Without turning the MADC clock on, no MADC conversions occur. $ cat /sys/class/hwmon/hwmon0/device/in8_input [ 53.428436] twl4030_madc twl4030_madc: conversion timeout! cat: read error: Resource temporarily unavailable Signed-off-by: Kyle Manna Signed-off-by: Samuel Ortiz

mfd: Add twl4030 madc driver

2011-03-23T09:42:00Z

Introducing a driver for MADC on TWL4030 powerIC. MADC stands for monitoring ADC. This driver monitors the real time conversion of analog signals like battery temperature, battery cuurent etc. Signed-off-by: Keerthy Signed-off-by: Samuel Ortiz
