What: /sys/bus/iio/devices/iio:deviceX/auto_zeroing_mux_enable
KernelVersion: 6.4
Contact: linux-iio@vger.kernel.org
Description:
This attribute is used to enable the analog input multiplexer
auto-zeroing algorithm (the input multiplexer and the ADC
include an offset cancellation algorithm that cancels the offset
contribution of the ADC). When the offset cancellation algorithm
is enabled, ADC takes two conversions, one with the differential
input as VIN+/VIN-, one with VIN+/VIN- inverted. In this case the
conversion time is multiplied by two compared to the default
case where the algorithm is disabled. This technique allows the
cancellation of the ADC offset error and the achievement of
ultra-low offset without any digital calibration. The resulting
offset is the residue of the difference between the two
conversions, which is on the order of magnitude of the noise
floor. This offset is effectively canceled at every conversion,
so the residual offset error temperature drift is extremely low.
Write '1' to enable it, write '0' to disable it.
What: /sys/bus/iio/devices/iio:deviceX/auto_zeroing_ref_enable
KernelVersion: 6.4
Contact: linux-iio@vger.kernel.org
Description:
This attribute is used to enable the chopping algorithm for the
internal voltage reference buffer. This setting has no effect
when external voltage reference is selected.
Internal voltage reference buffer injects a certain quantity of
1/f noise into the system that can be modulated with the
incoming input signals and can limit the SNR performance at
higher Oversampling Ratio values (over 256). To overcome this
limitation, the buffer includes an auto-zeroing algorithm that
greatly reduces (cancels out) the 1/f noise and cancels the
offset value of the reference buffer. As a result, the SNR of
the system is not affected by this 1/f noise component of the
reference buffer, even at maximum oversampling ratio values.
Write '1' to enable it, write '0' to disable it.

title: Analog Devices AD2S1210 Resolver-to-Digital Converter
maintainers:
- Michael Hennerich <michael.hennerich@analog.com>
description: |
The AD2S1210 is a complete 10-bit to 16-bit resolution tracking
resolver-to-digital converter, integrating an on-board programmable
sinusoidal oscillator that provides sine wave excitation for
resolvers.
The AD2S1210 allows the user to read the angular position or the
angular velocity data directly from the parallel outputs or through
the serial interface.
The mode of operation of the communication channel (parallel or serial) is
selected by the A0 and A1 input pins. In normal mode, data is latched by
toggling the SAMPLE line and can then be read directly. In configuration mode,
data is read or written using a register access scheme (address byte with
read/write flag and data byte).
A1 A0 Result
0 0 Normal mode - position output
0 1 Normal mode - velocity output
1 0 Reserved
1 1 Configuration mode
In normal mode, the resolution of the digital output is selected using
the RES0 and RES1 input pins. In configuration mode, the resolution is
selected by setting the RES0 and RES1 bits in the control register.
RES1 RES0 Resolution (Bits)
0 0 10
0 1 12
1 0 14
1 1 16
Note on SPI connections: The CS line on the AD2S1210 should hard-wired to
logic low and the WR/FSYNC line on the AD2S1210 should be connected to the
SPI CSn output of the SPI controller.

Description
-----------
This is a simple EEPROM module meant to enable reading the first 256 bytes
of an EEPROM (on a SDRAM DIMM for example). However, it will access serial
EEPROMs on any I2C adapter. The supported devices are generically called
24Cxx, and are listed above; however the numbering for these
industry-standard devices may vary by manufacturer.
This module was a programming exercise to get used to the new project
organization laid out by Frodo, but it should be at least completely
effective for decoding the contents of EEPROMs on DIMMs.
DIMMS will typically contain a 24C01A or 24C02, or the 34C02 variants.
The other devices will not be found on a DIMM because they respond to more
than one address.
DDC Monitors may contain any device. Often a 24C01, which responds to all 8
addresses, is found.
Recent Sony Vaio laptops have an EEPROM at 0x57. We couldn't get the
specification, so it is guess work and far from being complete.
The Microchip 24AA52/24LCS52, ST M34C02, and others support an additional
software write protect register at 0x30 - 0x37 (0x20 less than the memory
location). The chip responds to "write quick" detection at this address but
does not respond to byte reads. If this register is present, the lower 128
bytes of the memory array are not write protected. Any byte data write to
this address will write protect the memory array permanently, and the
device will no longer respond at the 0x30-37 address. The eeprom driver
does not support this register.
Lacking functionality
---------------------
* Full support for larger devices (24C04, 24C08, 24C16). These are not
typically found on a PC. These devices will appear as separate devices at
multiple addresses.
* Support for really large devices (24C32, 24C64, 24C128, 24C256, 24C512).
These devices require two-byte address fields and are not supported.
* Enable Writing. Again, no technical reason why not, but making it easy
to change the contents of the EEPROMs (on DIMMs anyway) also makes it easy
to disable the DIMMs (potentially preventing the computer from booting)
until the values are restored somehow.
Use
---
After inserting the module (and any other required SMBus/i2c modules), you
should have some EEPROM directories in ``/sys/bus/i2c/devices/*`` of names such
as "0-0050". Inside each of these is a series of files, the eeprom file
contains the binary data from EEPROM.

* DMA bus mastering is disabled and any pending DMA request are flushed. Once
* the response is returned, the devices are guaranteed to no longer issue DMA
* requests or raise MSI interrupts. Further device MMIO accesses may have
* undefined results. While the bus reset is asserted, any of the enumeration
* or device configuration MCDIs will fail with EAGAIN. It is only legal to
* reload the relevant PL region containing CDX devices if the corresponding CDX
* bus is in reset. Depending on the implementation, the firmware may or may
* not enforce this restriction and it is up to the caller to make sure this

* This module provides the following basic functions:
*
* comedi_8254_init() / comedi_8254_mm_init()
* comedi_8254_io_alloc() / comedi_8254_mm_alloc()
* Initializes this module to access the 8254 registers. The _mm version
* sets up the module for MMIO register access the other for PIO access.
* The pointer returned from these functions is normally stored in the
* comedi_device dev->pacer and will be freed by the comedi core during
* the driver (*detach). If a driver has multiple 8254 devices, they need
* to be stored in the drivers private data and freed when the driver is
* detached.
* sets up the module for MMIO register access; the _io version sets it
* up for PIO access. These functions return a pointer to a struct
* comedi_8254 on success, or an ERR_PTR value on failure. The pointer
* returned from these functions is normally stored in the comedi_device
* dev->pacer and will be freed by the comedi core during the driver
* (*detach). If a driver has multiple 8254 devices, they need to be
* stored in the drivers private data and freed when the driver is
* detached. If the ERR_PTR value is stored, code should check the
* pointer value with !IS_ERR(pointer) before freeing.
*
* NOTE: The counters are reset by setting them to I8254_MODE0 as part of
* this initialization.
