The AD7606B is a 16-bit ADC that supports simultaneous sampling of 8 channels. It is pin compatible to AD7606, but adds extra modes by writing to the register map. The AD7606B can be configured to work in software mode by setting all oversampling pins to high. This mode is selected by default. The oversampling ratio is configured from the OS_MODE register (address 0x08) with the addition of OS=128 and OS=256 that were not available in hardware mode. The device is configured to output data on a single spi channel, but this configuration must be done right after restart. That is why the delay was removed for devices which doesn't require it. Moreover, in software mode, the range gpio has no longer its function. Instead, the scale can be configured individually for each channel from the RANGE_CH registers (address 0x03 to 0x06). Besides the already supported ±10 V and ±5 V ranges, software mode can also accommodate the ±2.5 V range. Signed-off-by:

On Spreadtrum platform, the headphone will read one ADC channel multiple times to identify the headphone type, and the headphone identification is sensitive of the ADC reading time. And we found it will take longer time to reading ADC data by using interrupt mode comparing with the polling mode, thus we should change to polling mode to improve the efficiency of reading data, which can identify the headphone type successfully.

This patch removes the reference voltage entry from the platform_data structure. This is no longer needed since the reference voltage is obtained from the device tree. With this we also remove the entire ad7192.h file. The undefined reference voltage warning is promoted to an error signaling a problem with the device tree. Signed-off-by:

Caught via static-analysis checker: ``` drivers/iio/imu/adis16460.c 152 static int adis16460_set_freq(struct iio_dev *indio_dev, int val, int val2) 153 { 154 struct adis16460 *st = iio_priv(indio_dev); 155 unsigned int t; ^^^^^^^^^^^^^^ 156 157 t = val * 1000 + val2 / 1000; 158 if (t <= 0) ^^^^^^ Unsigned is not less than zero. ``` The types of `val` && `val2` are obtained from the IIO `write_raw` hook, so userspace can provide negative values, which can cause weird behavior after conversion to unsigned. This patch changes the sign of variable `t` so that -EINVAL will be returned for negative values as well.

The KIOX010A and KIOX020A ACPI ids go hand in hand, they are used in yoga style 2-in-1s, with KIOX010A indicating the KXCJ91008 sensor in the display of the 2-in-1 and KIOX020A indicating the KXCJ91008 sensor in the base. Improve the existing comment on the "KIOX010A" kx_acpi_match table entry to make clear we are talking about a yoga-style (360 degree hinges) device here and add a similar comment to the "KIOX020A" entry.

Static structure apex_desc, of type gasket_driver_desc, is used only as an argument to the functions gasket_register_device() and gasket_unregister_device().
