iio: inkern: fix iio_convert_raw_to_processed_unlocked

2013-07-25T21:07:23+00:00

commit f91d1b63a4e096d3023aaaafec9d9d3aff25997f upstream.

When reading IIO_CHAN_INFO_OFFSET, the return value of iio_channel_read() for
success will be IIO_VAL*, checking for 0 is not correct.

Without this fix the offset applied by iio drivers will be ignored when
converting a raw value to one in appropriate base units (e.g mV) in
a IIO client drivers that use iio_convert_raw_to_processed including
iio-hwmon.

inkern: iio_device_put after incorrect return/goto

2013-06-04T17:28:21+00:00

The code uses

    return foo;
    goto err_type;

when instead the form should have been

    ret = foo;
    goto err_type;

Here this causes a useful iio_device_put to be skipped.

iio: exynos_adc: fix wrong structure extration in suspend and resume

2013-05-22T21:15:20+00:00

The exynos_adc device structure was wrongly extracted from the dev*
correcting the same.

Using the regular conversion of
struct device* -> struct platform_device* -> struct exynos_adc* seems wrong.
Instead we should be doing
struct device* -> struct iio_dev* -> struct exynos_adc*

iio: dac: Fix build error when CONFIG_SPI_MASTER=y && CONFIG_I2C=m

2013-05-22T21:14:58+00:00

This patch fixes below build error when CONFIG_SPI_MASTER=y && CONFIG_I2C=m:

drivers/built-in.o: In function `ad5064_i2c_write':
drivers/iio/dac/ad5064.c:608: undefined reference to `i2c_master_send'
drivers/built-in.o: In function `ad5064_i2c_register_driver':
drivers/iio/dac/ad5064.c:646: undefined reference to `i2c_register_driver'
drivers/built-in.o: In function `ad5064_i2c_unregister_driver':
drivers/iio/dac/ad5064.c:651: undefined reference to `i2c_del_driver'
make: *** [vmlinux] Error 1

When CONFIG_I2C=m, meaning we can't build the drivers in with I2C support.
Thus don't allow the drivers to be compiled as built-in when CONFIG_I2C=m.

The real fix though is to break the driver apart into a SPI part, an I2C part
and a common part. But that's something for 3.11 while this is something for
3.10/stable.

iio: at91_adc: fix missing Sample and Hold time

2013-04-02T18:22:16+00:00

On the at91_adc a minimal Sample and Hold Time is necessary for the ADC to
guarantee the best converted final value between two channels selection.
This time has to be programmed through the bitfield SHTIM in the
Mode Register ADC_MR.
