Staging / IIO driver updates for 5.10-rc1
Here is the large set of staging and IIO driver updates for 5.10-rc1. Included in here are: - new IIO drivers - new IIO driver frameworks - various IIO driver fixes and updates - IIO device tree conversions to yaml - so many minor staging driver coding style cleanups - most cdev driver moved out of staging - no new drivers added or removed Full details are in the shortlog. All of these have been in linux-next for a while with no reported issues.

Analog Devices AD7768-1 ADC device driver
|
||||
|
||||
Required properties for the AD7768-1:
|
||||
|
||||
- compatible: Must be "adi,ad7768-1"
|
||||
- reg: SPI chip select number for the device
|
||||
- spi-max-frequency: Max SPI frequency to use
|
||||
see: Documentation/devicetree/bindings/spi/spi-bus.txt
|
||||
- clocks: phandle to the master clock (mclk)
|
||||
see: Documentation/devicetree/bindings/clock/clock-bindings.txt
|
||||
- clock-names: Must be "mclk".
|
||||
- interrupts: IRQ line for the ADC
|
||||
see: Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
|
||||
- vref-supply: vref supply can be used as reference for conversion
|
||||
- adi,sync-in-gpios: must be the device tree identifier of the SYNC-IN pin. Enables
|
||||
synchronization of multiple devices that require simultaneous sampling.
|
||||
A pulse is always required if the configuration is changed in any way, for example
|
||||
if the filter decimation rate changes. As the line is active low, it should
|
||||
be marked GPIO_ACTIVE_LOW.
|
||||
|
||||
Optional properties:
|
||||
|
||||
- reset-gpios : GPIO spec for the RESET pin. If specified, it will be asserted during
|
||||
driver probe. As the line is active low, it should be marked GPIO_ACTIVE_LOW.
|
||||
|
||||
Example:
|
||||
|
||||
adc@0 {
|
||||
compatible = "adi,ad7768-1";

ADS1015 (I2C)
|
||||
|
||||
This device is a 12-bit A-D converter with 4 inputs.
|
||||
|
||||
The inputs can be used single ended or in certain differential combinations.
|
||||
|
||||
For configuration all possible combinations are mapped to 8 channels:
|
||||
0: Voltage over AIN0 and AIN1.
|
||||
1: Voltage over AIN0 and AIN3.
|
||||
2: Voltage over AIN1 and AIN3.
|
||||
3: Voltage over AIN2 and AIN3.
|
||||
4: Voltage over AIN0 and GND.
|
||||
5: Voltage over AIN1 and GND.
|
||||
6: Voltage over AIN2 and GND.
|
||||
7: Voltage over AIN3 and GND.
|
||||
|
||||
Each channel can be configured individually:
|
||||
- pga is the programmable gain amplifier (values are full scale)
|
||||
0: +/- 6.144 V
|
||||
1: +/- 4.096 V
|
||||
2: +/- 2.048 V (default)
|
||||
3: +/- 1.024 V
|
||||
4: +/- 0.512 V
|
||||
5: +/- 0.256 V

|
||||
- interrupts: the interrupt indicating end of sampling
|
||||
- clocks: phandle and clock identifier (see clock-names)
|
||||
- clock-names: mandatory clocks:
|
||||
- "clkin" for the reference clock (typically XTAL)
|
||||
- "core" for the SAR ADC core clock
|
||||
optional clocks:
|
||||
- "adc_clk" for the ADC (sampling) clock
|
||||
- "adc_sel" for the ADC (sampling) clock mux
|
||||
- vref-supply: the regulator supply for the ADC reference voltage
|
||||
- #io-channel-cells: must be 1, see ../iio-bindings.txt
|
||||
|
||||
Optional properties:
|
||||
- amlogic,hhi-sysctrl: phandle to the syscon which contains the 5th bit
|
||||
of the TSC (temperature sensor coefficient) on
|
||||

|
||||
temperature sensor)
|
||||
- nvmem-cells: phandle to the temperature_calib eFuse cells
|
||||
- nvmem-cell-names: if present (to enable the temperature sensor
|
||||
calibration) this must contain "temperature_calib"

The node for this driver must be a child node of a SPI controller, hence
|
||||
all mandatory properties described in
|
||||
|
||||
Documentation/devicetree/bindings/spi/spi-bus.txt
|
||||
|
||||
must be specified.

"microchip,mcp3553"
|

|
||||
NOTE: The use of the compatibles with no vendor prefix
|
||||
is deprecated and only listed because old DT use them.
|
||||
|
||||
- spi-cpha, spi-cpol (boolean):
|
||||
Either SPI mode (0,0) or (1,1) must be used, so specify
|
||||
none or both of spi-cpha, spi-cpol. The MCP3550/1/3
|
||||
is more efficient in mode (1,1) as only 3 instead of
|
||||
4 bytes need to be read from the ADC, but not all SPI
|
||||
masters support it.
|
||||
|
||||
- vref-supply: Phandle to the external reference voltage supply.
|
||||
|
||||
Examples:
|
||||
spi_controller {
|
||||
mcp3x0x@0 {
|
||||
compatible = "microchip,mcp3002";
|
||||

||||
Required properties:
|
||||
- compatible: "nuvoton,npcm750-adc" for the NPCM7XX BMC.
|
||||
- reg: specifies physical base address and size of the registers.
|
||||
- interrupts: Contain the ADC interrupt with flags for falling edge.
|
||||
- resets : phandle to the reset control for this device.
|
||||
|
||||
Optional properties:
|

- vref-supply: The regulator supply ADC reference voltage, in case the
|
||||
vref-supply is not added the ADC will use internal voltage
|
||||
reference.
|

|
||||
|
||||
adc: adc@f000c000 {

Freescale vf610 Analog to Digital Converter bindings
|
||||
|
||||
The devicetree bindings are for the new ADC driver written for
|
||||
vf610/i.MX6slx and upward SoCs from Freescale.
|
||||
|
||||
Required properties:
|
||||
- compatible: Should contain "fsl,vf610-adc"
|
||||
- reg: Offset and length of the register set for the device
|
||||
- interrupts: Should contain the interrupt for the device
|
||||
- clocks: The clock is needed by the ADC controller, ADC clock source is ipg clock.
|
||||
- clock-names: Must contain "adc", matching entry in the clocks property.
|
||||
- vref-supply: The regulator supply ADC reference voltage.
|
||||
|
||||
Recommended properties:
|
||||
- fsl,adck-max-frequency: Maximum frequencies according to datasheets operating
|
||||
requirements. Three values are required, depending on conversion mode:
|
||||
- Frequency in normal mode (ADLPC=0, ADHSC=0)
|
||||
- Frequency in high-speed mode (ADLPC=0, ADHSC=1)
|
||||
- Frequency in low-power mode (ADLPC=1, ADHSC=0)
|
||||
- min-sample-time: Minimum sampling time in nanoseconds. This value has
|
||||
to be chosen according to the conversion mode and the connected analog
|
||||
source resistance (R_as) and capacitance (C_as). Refer the datasheet's
|
||||
operating requirements. A safe default across a wide range of R_as and
|
||||
C_as as well as conversion modes is 1000ns.
|
||||
|
||||
Example:
|
||||
adc0: adc@4003b000 {
|
||||
compatible = "fsl,vf610-adc";
|
||||
reg = <0x4003b000 0x1000>;
|
||||
interrupts = <0 53 0x04>;
|
||||
clocks = <&clks VF610_CLK_ADC0>;
|
||||
clock-names = "adc";
|
||||
fsl,adck-max-frequency = <30000000>, <40000000>,
|
||||
<20000000>;
|
||||
vref-supply = <®_vcc_3v3_mcu>;
