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.

iio:adc: Add Xilinx XADC driver The Xilinx XADC is a ADC that can be found in the series 7 FPGAs from Xilinx. The XADC has a DRP interface for communication. Currently two different frontends for the DRP interface exist. One that is only available on the ZYNQ family as a hardmacro in the SoC portion of the ZYNQ. The other one is available on all series 7 platforms and is a softmacro with a AXI interface. This driver supports both interfaces and internally has a small abstraction layer that hides the specifics of these interfaces from the main driver logic. The ADC has a couple of internal channels which are used for voltage and temperature monitoring of the FPGA as well as one primary and up to 16 channels auxiliary channels for measuring external voltages. The external auxiliary channels can either be directly connected each to one physical pin on the FPGA or they can make use of an external multiplexer which is responsible for multiplexing the external signals onto one pair of physical pins. The voltage and temperature monitoring channels also have an event capability which allows to generate a interrupt when their value falls below or raises above a set threshold. Buffered sampling mode is supported by the driver, but only for AXI-XADC since the ZYNQ XADC interface does not have capabilities for supporting buffer mode (no end-of-conversion interrupt). If buffered mode is supported the driver will register two triggers. One "xadc-samplerate" trigger which will generate samples with the configured samplerate. And one "xadc-convst" trigger which will generate one sample each time the CONVST (conversion start) signal is asserted.
