2020-07-22iio: imu: st_lsm6dsx: reset hw ts after resumeLorenzo Bianconi
Reset hw time samples generator after system resume in order to avoid disalignment between system and device time reference since FIFO batching and time samples generator are disabled during suspend.

2020-07-22iio: dac: ad5592r: fix unbalanced mutex unlocks in ad5592r_read_raw()Alexandru Ardelean
There are 2 exit paths where the lock isn't held, but try to unlock the mutex when exiting. In these places we should just return from the function. A neater approach would be to cleanup the ad5592r_read_raw(), but that would make this patch more difficult to backport to stable versions.

2020-07-22iio: core: fix/re-introduce back parent assignmentAlexandru Ardelean
This was introduced initially via commit 78289b4a58b58 ("iio: core: pass parent device as parameter during allocation"), but was accidentally removed via commit 6d4ebd565d15f ("iio: core: wrap IIO device into an iio_dev_opaque object"). This looks like a rebase gone wrong, and ends up breaking devicetree bindings of IIO clients. This change adds back the parent assignment.

2020-07-22iio: adc: ad7124: move chip ID & name on the chip_info tableAlexandru Ardelean
This change does the following: * removes the SPI device table in favor of the OF device table * adds 'name' && 'chip_id' fields to chip_info * implements chip ID & silicon revision checking; the device ID for AD7124-4 is 0x0, so just checking that value can be useless; but at least the silicon revision isn't 0, so a non-zero value can be used to check that "a" device is on the SPI bus; it's probably the best way to narrow it down to one of the 2 AD7124 chip IDs Signed-off-by: Alexandru Ardelean <alexandru.ardelean@analog.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2020-07-20IIO: Ingenic JZ47xx: Add touchscreen mode.Artur Rojek
The SADC component in JZ47xx SoCs provides support for touchscreen operations (pen position and pen down pressure) in single-ended and differential modes. The touchscreen component of SADC takes a significant time to stabilize after first receiving the clock and a delay of 50ms has been empirically proven to be a safe value before data sampling can begin. Of the known hardware to use this controller, GCW Zero and Anbernic RG-350 utilize the touchscreen mode by having their joystick(s) attached to the X/Y positive/negative input pins. JZ4770 and later SoCs introduce a low-level command feature. With it, up to 32 commands can be programmed, each one corresponding to a sampling job. It allows to change the low-voltage reference, the high-voltage reference, have them connected to VCC, GND, or one of the X-/X+ or Y-/Y+ pins. This patch introduces support for 6 stream-capable channels: - channel #0 samples X+/GND - channel #1 samples Y+/GND - channel #2 samples X-/GND - channel #3 samples Y-/GND - channel #4 samples X+/X- - channel #5 samples Y+/Y- Being able to sample X-/GND and Y-/GND is useful on some devices, where one joystick is connected to the X+/Y+ pins, and a second joystick is connected to the X-/Y- pins. All the boards which probe this driver have the interrupt provided from Device Tree, with no need to handle a case where the IRQ was not provided.
