iio: adc: add new lp8788 adc driver
TI LP8788 PMU provides regulators, battery charger, ADC,
RTC, backlight driver and current sinks.
This patch enables the LP8788 ADC functions.
The LP8788 ADC has several ADC input selection and supports 12bit resolution.
Internal operation of getting ADC is access to registers of LP8788.
The LP8788 ADC uses exported functions for accessing these registers.
(exported by LP8788 MFD device driver)
This driver supports IIO_CHAN_INFO_RAW and SCALE.
So the IIO consumer can calculate the value with raw and scale.
The unit of scale is micro.
(ADC Input Selection)
Voltage: battery voltage (MAX 5.0, 5.5 and 6.0V)
charger input voltage
four general ADC inputs
coin cell voltage
Current: battery charging current
Temperature: IC temperature
(The IIO map for the IIO consumer)
The ADC input is configurable in the platform side.
Even though this platform data is not defined,
the default IIO map is created for supporting the power supply driver.
The battery voltage and temperature are used inside this driver.
(History)
Patch v6.
(a) Fix scale value for each ADC input selection
Voltage and current type are mili unit and temperature is degree.
To calculate the IC temperature,
temp = raw * scaleint + (raw * scalepart)/ 1000000, scaleint is always 0.
= raw * 0.061050, raw: 0 ~ 4095
Then range of IC temperature(ADC result) is 0 ~ 250'C
(b) Reorganization of the IIO channel Spec
Remove address, scan_type and scan_index and rollback the datasheet name.
The reason why 'address' field is unnecessary is no relation with each channel.
Moreover, to get the raw ADC value, the address info is not only one register
but also several registers.
Therefore specific function(lp8788_get_adc_result) is called rather than
using one 'address' field.
(c) Fix coding style
Remove duplicated checking routine while unregistering the IIO map.
Fix code for space and parenthesis.
Patch v5.
Fix default consumer name as 'lp8788-charger'.
Add mutex for ADC read operation.
Reorganization on lp8788_adc_read_raw().
Patch v4.
Fix adc_raw function: support RAW and SCALE channel info.
Change LP8788 ADC platform data - iio map.
Enables the default IIO map.
Patch v3.
Fix wrong size of allocating iio private data.
Fix coding styles.
Patch v2.
Support RAW and SCALE interface for IIO consumer.
Clean up the iio channel spec macro.

These ADCs are marketed as single-channel 22 bit delta-sigma ADCs, but
in reality their resolution is 21 bit with an overrange or underrange
of 12% beyond Vref. In other words, "full scale" means +/- 2^20.
This driver does not explicitly signal back to the user when an
overrange or underrange occurs, but the user can detect it by comparing
the raw value to +/- 2^20 (or the scaled value to Vref).
The chips feature an extended temperature range and high accuracy,
low noise characteristics, but their conversion times are slow with
up to 80 ms +/- 2% (on the MCP3550-50).
Hence, unlike the other ADCs supported by the driver, conversion does
not take place in realtime upon lowering CS. Instead, CS is asserted
for 8 usec to start the conversion. After waiting for the duration of
the conversion, the result can be fetched. While waiting, control of
the bus is ceased so it may be used by a different device.
After the result has been fetched and 10 us have passed, the chip goes
into shutdown and an additional power-up delay of 144 clock periods is
then required to wake the analog circuitry upon the next conversion
(footnote below table 4-1, page 16 in the spec).
Optionally, the chips can be used in so-called "continuous conversion
mode": Conversions then take place continuously and the last result may
be fetched at any time without observing a delay. The mode is enabled
by permanently driving CS low, e.g. by wiring it to ground. The driver
only supports "single conversion mode" for now but should be adaptable
to "continuous conversion mode" with moderate effort.
The chips clock out a 3 byte word, unlike the other ADCs supported by
the driver which all have a lower resolution than 16 bit and thus make
do with 2 bytes. Calculate the word length on probe by rounding up the
resolution to full bytes. Crucially, if the clock idles low, the
transfer is preceded by a useless Data Ready bit which increases its
length from 24 bit to 25 bit = 4 bytes (section 5.5 in the spec).
Autosense this based on the SPI slave's configuration.

iio: stx104: Add IIO support for the ADC channels
The Apex Embedded Systems STX104 features 16 channels of single-ended (8
channels of true differential) 16-bit analog input. Differential input
configuration may be selected via a physical jumper on the device.
Similarly, input polarity (unipolar/bipolar) is configured via a
physical jumper on the device.
Input gain selection is available to the user via software, thus
allowing eight possible input ranges: +-10V, +-5V, +-2.5V, +-1.25V,
0 to 10V, 0 to 5V, 0 to 2.5V, and 0 to 1.25V. Four input gain
configurations are supported: x1, x2, x4, and x8.
This ADC resolution is 16-bits (1/65536 of full scale). Analog input
samples are taken on software trigger; neither FIFO sampling nor
interrupt triggering is supported by this driver.
The Apex Embedded Systems STX104 is primarily an analog-to-digital
converter device. The STX104 IIO driver was initially placed in the DAC
directory because only the DAC portion of the STX104 was supported at
the time. Now that ADC support has been added to the STX104 IIO driver,
the driver should be moved to the more appropriate ADC directory.

iio: adc: sun4i-gpadc-iio: add support for A33 thermal sensor
This adds support for the Allwinner A33 thermal sensor.
Unlike the A10, A13 and A31, the Allwinner A33 only has one channel
which is dedicated to the thermal sensor. Moreover, its thermal sensor
does not generate interruptions, thus we only need to directly read the
register storing the temperature value.
The MFD used by the A10, A13 and A31, was created to avoid breaking the
DT binding, but since the nodes for the ADC weren't there for the A33,
it is not needed.
Though the A33 does not have an internal ADC, it has a thermal sensor
which shares the same registers with GPADC of the already supported SoCs
and almost the same bits, for the same purpose (thermal sensor).
The thermal sensor behaves exactly the same (except the presence of
interrupts or not) on the different SoCs.

disabling CONFIG_THERMAL_OF. However, the thermal sensor should be

enabled by default since the SoC temperature is usually more critical

iio: twl6030-gpadc: TWL6030, TWL6032 GPADC driver
The GPADC is general purpose ADC found on TWL6030, and TWL6032 PMIC,
known also as Phoenix and PhoenixLite.
The TWL6030 and TWL6032 have GPADC with 17 and 19 channels
respectively. Some channels have current source and are used for
measuring voltage drop on resistive load for detecting battery ID
resistance, or measuring voltage drop on NTC resistors for external
temperature measurements. Some channels measure voltage, (i.e. battery
voltage), and have voltage dividers, thus, capable to scale voltage.
Some channels are dedicated for measuring die temperature.
Some channels are calibrated in 2 points, having offsets from ideal
values kept in trim registers. This is used to correct measurements.
The differences between GPADC in TWL6030 and TWL6032:
- 10 bit vs 12 bit ADC;
- 17 vs 19 channels;
- channels have different purpose(i.e. battery voltage
channel 8 vs channel 18);
- trim values are interpreted differently.
Based on the driver patched from Balaji TK, Graeme Gregory, Ambresh K,
Girish S Ghongdemath.
