10 years agostaging: dgap: Remove printks associated with sysfile creation
Mark Hounschell [Thu, 6 Mar 2014 18:57:55 +0000 (13:57 -0500)]
staging: dgap: Remove printks associated with sysfile creation

This patch removes printks associated with sysfile creation
and changes the dgap_create_driver_sysfiles function to return
an int so we can check for errors in the sysfile creation
process.

The printk's were flagged by checkpatch but then
driver_create_file was flagged by checkpatch for
not checking its return. So we remove the printk's
and check the return of driver_create_file.

Lars-Peter Clausen [Mon, 17 Feb 2014 14:10:00 +0000 (14:10 +0000)]
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.

document describes the bindings for both of them since the bindings are very

Each of them needs:
* A address range where the registers are mapped
* An interrupt number for the device interrupt
* A clock. For the the ZYNQ hardmacro interface this is the modules PCAP
  clock, for the AXI softmacro it is the AXI bus interface clock.

Additionally the bindings specify whether an external multiplexer is used and in
which mode it is used. The devicetree bindings also describe which external
channels are connected and in which configuration.
