2021-10-21iio: adc: ti_am335x_adc: Wait the idle state to avoid stallsMiquel Raynal
At least on a am4372, a simple: $ cat /sys/bus/iio/devices/iio\:deviceX/in_voltage*_raw can stall forever. It seems that it comes from the fact that the internal state machine does not have enough time to return to its idle state in this situation before receiving another request, leading to an internal stall.

There was in the past a typo in the coordinate readouts property. The bindings have been updated, the touchscreen driver as well and now supports both.

2021-10-21mfd: ti_am335x_tscadc: Introduce a helper to deal with the type of hardwareMiquel Raynal
One way of knowing which hardware we are dealing with is to check the compatible string. When this must be done at several places, it's best and certainly more clear to use a helper for that. Introduce ti_adc_with_touchscreen() to indicate if there is a touchscreen controller available (meaning it's an am33xx-like ADC). This helper does not indicate if it is actually used (that is the purpose of the use_tsc boolean). Introducing this helper helps making a difference in the code between what is generic to both types of ADCs and what is specific to the am33xx hardware before introducing support for the am437x hardware.

2021-10-21mfd: ti_am335x_tscadc: Drop useless definitions from the headerMiquel Raynal
Drop useless definitions from the header like the "masks" definitions which are only used by the following definition. It could be possible to got even further by removing these definitions entirely and use FIELD_PREP() macros from the code directly, but while I have no troubles making these changes in the header, changing the values in the code directly could darkening a bit the logic and hardening future git-blames for very little added value IMHO (but this is of course a personal taste). Certain macros are using GENMASK() to define the value of a particular field, while this is purely "by chance" that the value and the mask have the same value. In this case, drop the "mask" definition, use FIELD_PREP() and GENMASK() in the macro defining the field, and use the new macro to define the particular value by feeding directly the actual number advertised in the datasheet into that macro, as in: -#define STEPCONFIG_RFM_VREFN GENMASK(24, 23) -#define STEPCONFIG_RFM(val) FIELD_PREP(STEPCONFIG_RFM_VREFN, (val)) +#define STEPCONFIG_RFM(val) FIELD_PREP(GENMASK(24, 23), (val)) +#define STEPCONFIG_RFM_VREFN STEPCONFIG_RFM(3) Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Reviewed-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Signed-off-by: Lee Jones <lee.jones@linaro.org> Link: https://lore.kernel.org/r/20211015081506.933180-30-miquel.raynal@bootlin.com

TI AM335X TRM [1] states that most of the configuration should be set in the control register in the first place, before actually enabling the hardware with the subsystem enable bit. So far only half of the configuration was made in the first step (before enabling the "subsystem"), which does not make really sense. Also, the probe and the resume patch were acting differently. Let's harmonize all this by following these steps: 1/ Configure the CLKDIV register 2/ Configure the CTRL register 3/ Configure the idle configuration 4/ Really enable the device by rewriting the CTRL register with the subsystem enable bit set.

This touchscreen controller is already described in a text file: Documentation/devicetree/bindings/input/touchscreen/ti-tsc-adc.txt After introducing a proper description of the MFD, this is the second step. The file cannot be removed yet as it also contains an ADC description.
