Please add CONFIG_MCP320X=m to standard config

[tgaryet]

mcp320x.c is the driver for a set of Microchip A2D converters:

10 Bit converters
MCP3001
MCP3002
MCP3004
MCP3008

12 bit converters
MCP3201
MCP3202
MCP3204
MCP3208

I am creating a HAT module that contains the MCP3004 A2D converter attached to the SPI. Since the HAT device tree would reference this driver, it would be advantageous to have it in the standard configuration.

Please add:
CONFIG_MPC320X=m

to the standard configuration.

Sounds okay.

Thank you.

I am unfamiliar with how I get access to this when it is done.

I've pushed the patch that enables this option. This will cause future builds to include the required driver.

The driver will appear first in the next rpi-update release, available via:

sudo rpi-update

Some time later it will appear in a Raspbian release, available via:

sudo apt-get update
sudo apt-get upgrade

Thank you,

This is now in latest rpi-update firmware. Please test and close if happy.

iio device exists...

pi@raspberrypi /sys/bus/iio/devices/iio:device0 $pi@raspberrypi /sys/bus/iio/devices/iio:device0 $ ls in_voltage*_raw
in_voltage0_raw in_voltage0-voltage1_raw in_voltage1_raw in_voltage2_raw in_voltage2-voltage3_raw in_voltage3_raw

A2D data reported...

Looks like it works.
