The MODULE_DEVICE_TABLE already creates proper alias. Having another MODULE_ALIAS causes the alias to be duplicated: $ modinfo cros_ec_dev.ko alias: platform:cros-ec-dev srcversion: F84A69D2156719A4F717A76 alias: platform:cros-ec-dev Signed-off-by:

Without the scale, the values returned to the user are just a picture of the input voltage against the full scale range of the ADC. We need to provide the actual conversion factor to get milli-Volts values. Signed-off-by:

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. Add a tiadc_wait_idle() helper to ensure no new conversion is requested while the FSM is still busy. Signed-off-by:

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. However, the MFD driver that is in charge of verifying the validity of the property only checks the bogus one. Add support for the correctly spelled DT property.

Introduce a new compatible that has another set of driver data, targeting am437x SoCs with a magnetic reader instead of the touchscreen and a more featureful set of registers. Signed-off-by:

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.

Just checking the number of wires will soon not be enough, add a boolean to indicate the actual use or not of the touchscreen. Certain checks only make sense when there is a touchscreen wired. Make these checks explicitly depend on the presence of the touchscreen. Signed-off-by:

The error message if we cannot retrieve the clock tells us that the touchscreen controller clock was unavailable. This is wrong, this is the "main" clock for the hardware block, it is not specific to the touchscreen and won't change when we will introduce ADC1/magnetic reader support so let's correct this comment.

We need to retrieve the number of wires used by the "secondary" device (the touchscreen or the magnetic reader). Let's rename tsc_wires to become tscmag_wires to clarify the fact that this variable can be used in both situations. Signed-off-by:

While the register list (and names) between ADC0 and ADC1 are pretty close, the bits inside changed a little bit. To avoid any future confusion, let's add the TSC prefix when some bits are in a register that is common to both revisions of the ADC, but are specific to the am33xx hardware. Signed-off-by:

This bit is common to all devices (ADC, Touchscreen, Magnetic reader) so make it clear that it can be used from any location by operating a mechanical rename: s/CNTRLREG_TSCSSENB/CNTRLREG_SSENB/ Signed-off-by:

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:

Clearly define the maximum open delay and sample delay. Use these definitions in place of a mask (which works because this is the first field in the register) and an open-coded value. While at it reword a little bit the error messages to make them look clearer and similar. Signed-off-by:

Clean the ti_am335x_tscadc.h header by: * converting masks to GENMASK() * converting regular shifts to BIT() * using FIELD_PREP() when relevant Sometimes reorder the lines to be able to use the relevant bitmask. Mind the s/%d/%ld/ change in a log due to the type change following the use of FIELD_PREP() in the header. Suggested-by:
