2018-03-24staging:iio:ade7854: Rework SPI write functionRodrigo Siqueira
The write operation using SPI has a many code duplications (similar to I2C) and four different interfaces per data size. This patch introduces a single function that centralizes the main task related to SPI.

2018-03-24staging:iio:ade7854: Rework I2C write functionRodrigo Siqueira
The write operation using I2C has many code duplications and four different interfaces per data size. This patch introduces a single function that centralizes the main tasks. The central function inserted by this patch can easily replace all the four functions related to the data size. However, this patch does not remove any code signature for keeping the meter module work and make easier to review this patch.

2018-03-24staging:iio:ade7854: Fix the wrong number of bits to readJohn Syne
Fixes: correctly handle the data size in the read operation for I2C The function ade7854_i2c_read_reg_32() have to invoke the i2c_master_recv() for read 32 bits values, however, the counter is set to 3 which means 24 bits. This patch fixes the wrong size of 24 bits, to 32 bits.

2018-03-17iio: adc: ad7780: remove IIO_CHAN_INFO_SAMP_FREQ supportAlexandru Ardelean
The `ad7780` driver does not implement setting/getting the sampling frequency. For the ad7780/ad7781 devices, the control is done via an external pin, and the ad7170/ad7171 devices have a fixed sampling rate (so, no control). For these devices, and similar other that may be added later on, a AD_SD_CHANNEL_NO_SAMPLE_FREQ() macro has been added, which doesn't set the IIO_CHAN_INFO_SAMP_FREQ flag.

2018-03-17iio: adc: ad7791: implement IIO_CHAN_INFO_SAMP_FREQAlexandru Ardelean
Now that the old read/write frequency sysfs attrs have been removed, we have a clean slate to implement IIO_CHAN_INFO_SAMP_FREQ. This driver also pre-dates IIO_CHAN_INFO_SAMP_FREQ, and this change implements this behavior. The `ad7791_write_raw` would have overlapped quite a bit with the old read/write frequency functions, making things a bit harder to follow.

2018-03-17iio: adc: ad7791: remove sample freq sysfs attributesAlexandru Ardelean
In the current state, these attributes are broken, because they are registered already, and the kernel throws a warning. The first registration happens via the `IIO_CHAN_INFO_SAMP_FREQ` flag from the `ad_sigma_delta` driver. In this commit these attrs are removed, and in the following the IIO_CHAN_INFO_SAMP_FREQ behavior will be implemented, which replaces these hooks. This is done to make things a bit easier to review as there is a bit of overlap in the patch if it's done all at once.

2018-03-17iio: stx104: Implement get_multiple callbackWilliam Breathitt Gray
The Apex Embedded Systems STX104 series of devices provides 4 TTL compatible lines of inputs accessed via a single 4-bit port. Since four input lines are acquired on a single port input read, the STX104 GPIO driver may improve multiple input reads by utilizing a get_multiple callback. This patch implements the stx104_gpio_get_multiple function which serves as the respective get_multiple callback.

It's about coordinating the condition for the pagelist fragment behavior between the two sides.
