2017-09-24dt-bindings: iio: adc: mcp320x: Update for mcp3550/1/3Lukas Wunner
All chips supported by this driver clock data out on the falling edge and latch data in on the rising edge, hence SPI mode (0,0) or (1,1) must be used. Furthermore, none of the chips has an internal reference voltage regulator, so an external supply is always required and needs to be specified in the device tree lest the IIO "scale" in sysfs cannot be calculated. Document these requirements in the device tree binding, add compatible strings for the newly supported mcp3550/1/3 and explain that SPI mode (0,0) should be preferred for these chips.

2017-09-24Staging: iio: meter: ade7759: update locking method for write frequencyKatie Dunne
iio_dev->mlock is to be used only by the IIO core for protecting device mode changes between INDIO_DIRECT and INDIO_BUFFER. This patch replaces the use of mlock with the already established buf_lock mutex. Introducing an 'unlocked' spi_write_reg_16 function to be used by ade7759_write_frequency avoids nested locks and maintains atomicity between bus and device frequency changes.

2017-09-24staging: iio: tsl2x7x: clean up limit checksDan Carpenter
The background of this code is that we can either use the default tables or load our own table with sysfs. The default tables are three element arrays of struct tsl2x7x_lux. If we load the table with sysfs then we can have as many as nine elements. Which ever way we do it, the last element is always zeroed out. The most interesting part of this patch is in the in_illuminance0_lux_table_show() function. We were using the wrong limit, "TSL2X7X_MAX_LUX_TABLE_SIZE * 3", when it should have been just "TSL2X7X_MAX_LUX_TABLE_SIZE". This creates a static checker warning that we are going of bounds. However, since the last element is always zeroed out, that means we hit the break statement and the code works correctly despite the wrong limit check. I made several related readability changes. The most notable that I changed the MAX_DEFAULT_TABLE_BYTES define which was: I renamed the define to TSL2X7X_DEFAULT_TABLE_BYTES because it's not the max size, it's the only size. Also the size should really be expressed as sizeof(struct tsl2x7x_lux) * 3. In other words, 12 * 3 instead of 4 * 9. It's 36 bytes either way, so this doesn't change the behavior. Finally, I created the TSL2X7X_DEF_LUX_TABLE_SZ define instead of using the magic number 3. I declared the default tables using that define to hopefully signal to future programmers that if they want to use a different size they have to update all the related code.

2017-09-24iio: adc: mcp320x: Drop unnecessary of_device_id attributesLukas Wunner

2017-09-24iio: adc: mcp320x: Speed up readout of single-channel ADCsLukas Wunner
Single-channel converters such as mcp3001, mcp3201, mcp3301 and the upcoming mcp3550/1/3 lack a MOSI pin, so there's no need to call mcp320x_channel_to_tx_data() for them. Moreover, instead of calling spi_read() for these converters, which generates an spi_message and spi_transfer on the stack on every readout, it's more efficient to use the spi_message and spi_transfer[] included in struct mcp320x (as we do for multi-channel ADCs), but initialize the spi_message only with the receive transfer.
