Some sensors could have only one full scale value. This means that the sensor hasn't a full scale register. This commit add a check on the configured full scale address to support such kind of sensors. Signed-off-by:

Since patch "i2c / ACPI: Use 0 to indicate that device does not have interrupt assigned" [1], 0 is not a valid i2c client irq anymore, so change all driver's checks accordingly. The same issue occurs when the device is instantiated via device tree with no IRQ, or from the i2c sysfs interface, even before the patch above.

This patch indends to make some cleanup and send printf error messages to stderr. The changes were performed with coccinelle for failure messages and manual for other cases, such as wrong usage messages. Signed-off-by:

TI's opt3001 light sensor is a simple and yet powerful little device. The device provides 99% IR rejection, automatic full-scale, very low power consumption and measurements from 0.01 to 83k lux. This patch adds support for that device using the IIO framework. See http://www.ti.com/product/opt3001 for more information. Signed-off-by:

This cleans up the most ugly workaround in this driver. There are no functional changes yet in the decoding algorithm, but we improve the following things: * Get rid of spurious warning messages on systems with fast HRTIMER. * If the clock is not fast enough for decoding to work, we give up immediately. * In that case we return EAGAIN instead of EIO, so it's easier to discriminate causes of failure. Returning EAGAIN is somewhat controversial: It's technically correct as a faster clock might become available. OTOH once all clocks are enabled this is a permanent error. There is no ECLOCKTOOSLOW error code. Signed-off-by:

The driver currently does not take into account the minimum sample time as per the Figure 6-8 Chapter 9.1.1 12-bit ADC electrical characteristics. We set a static amount of cycles instead of considering the sample time as a given value, which depends on hardware characteristics. Determine sampling frequencies by first reading the device tree property node and then calculating the required Long Sample Time Adder (LSTAdder) value, based on the ADC clock frequency and sample time value obtained from the device tree. This LSTAdder value is then used for calculating the sampling frequencies possible. In case the sample time property is not specified through the device tree, a safe default value of 1000ns is assumed. Signed-off-by:

In a later patch we will remove the duplicate codes. But the code also needs to execute dgap_remove_driver_sysfiles() if it is being called from dgap_remove_one() but if being called fron the error path of the dgap_init_module() then the sysfiles should not be removed. Signed-off-by:
