Immutable branch may be needed in input for a joystick set that is dependent on it.
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.

This change attaches the life-cycle of the kfifo buffer & IRQ to the parent-device. This in turn cleans up the exit & error paths, since we don't need to explicitly cleanup these resources. The main intent here is to remove the explicit cleanup of the 'indio_dev->buffer' via 'iio_kfifo_free(indio_dev->buffer);'. As we want to add support for multiple buffers per IIO device, having it exposed like this makes it tricky to consider a safe backwards compatible approach for it.

2020-07-07iio: at91-sama5d2_adc: remove usage of iio_priv_to_dev() helperAlexandru Ardelean
We may want to get rid of the iio_priv_to_dev() helper. The reason is that we will hide some of the members of the iio_dev structure (to prevent drivers from accessing them directly), and that will also mean hiding the implementation of the iio_priv_to_dev() helper inside the IIO core. Hiding the implementation of iio_priv_to_dev() implies that some fast-paths may not be fast anymore, so a general idea is to try to get rid of the iio_priv_to_dev() altogether. The iio_priv() helper won't be affected by the rework, as the iio_dev struct will keep a reference to the private information. For this driver, not using iio_priv_to_dev(), means reworking some paths to pass the iio device and using iio_priv() to access the private information, and also keeping a reference to the iio device for some quirky paths. One [quirky] path is the at91_adc_workq_handler() which requires the IIO device & the state struct to push to buffers. Since this requires the back-ref to the IIO device, the at91_adc_touch_pos() also uses it. This simplifies the patch a bit. The information required in this function is mostly for debugging purposes. Replacing it with a reference to the IIO device would have been a slightly bigger change, which may not be worth it (for just the debugging purpose and given that we need the back-ref to the IIO device anyway).
