The ASPEED SoC must deassert a reset in order to use the ADC peripheral. The device tree bindings are updated to document the resets phandle, and the example is updated to match what is expected for both the reset and clock phandle. Note that the bindings should have always had the reset controller, as the hardware is unusable without it. Signed-off-by:

STM32H7 ADC channels can be configured either as single ended or differential with 'st,adc-channels' or 'st,adc-diff-channels' (positive and negative input pair: <vinp vinn>, ...). Differential channels have different offset and scale, from spec: raw value = (full_scale / 2) * (1 + (vinp - vinn) / vref). Add offset attribute. Differential channels are selected by DIFSEL register. Negative inputs must be added to pre-selected channels as well (PCSEL). Signed-off-by:

Remove const array that defines channels. Build channels definition at probe time, when initializing channels (only for requested ones). This will ease adding differential channels support. Signed-off-by:

Reducing shunt and bus voltage range improves the accuracy, so allow altering the default settings. Both settings are exposed as gain values. While for the shunt voltage this is straightforward, the bus range settings of 32V (default) and 16V are mapped to gain values of 1 resp. 2, to provide a uniform API to userspace. As the gain settings are incorporated into the raw values by the sensor itself, adjusting of the scale attributes is not necessary. Signed-off-by:

While the config uses the physical value corresponding to the LSB for both the power and the bus voltage register, the shunt voltage is specified as parts of 1 mV. Use the LSB physical value for all registers. No functional change. Signed-off-by:

Lower bits of the INA219/220 bus voltage register are conversion status flags, properly shift the value. When reading via IIO buffer, the value is passed on unaltered, shifting is the responsibility of the user. Signed-off-by:

Added support for DMA transfers. The implementation uses the user watermark to decide whether DMA will be used or not. For watermark 1, DMA will not be used. If watermark is bigger, DMA will be used. Sysfs attributes are created to indicate whether the DMA is used, with hwfifo_enabled, and the current DMA watermark is readable in hwfifo_watermark. Minimum and maximum values are in hwfifo_watermark_min and hwfifo_watermark_max. Signed-off-by:

Add necessary casting to several places where we were doing 32-bit arithmetic (unsigned) to produce a 64-bit (unsigned long) result, to prevent the theoretical possibility of a 32-bit overflow during the arithmetic. FYI, these are unsigned long: ctx->param_bytes ctx->allocbytes These are unsigned int: bytes phdr->name_offset phdr->name_length Here is the test program demonstrating why we really need the casts: void main() { unsigned int i; unsigned long il; printf("sizeof(int) =%dn",sizeof(i)); printf("sizeof(long)=%dn",sizeof(il)); i = (unsigned int)((((unsigned long)(1)) << 32) - 1); printf("i = %un", i); il = i+1; printf("adding 1 withOUT cast = %lun", il); il = (unsigned long)i+1; printf("adding 1 WITH cast = %lun", il); } [selltc@mac tmp]$ gcc x.c -o x.out [selltc@mac tmp]$ ./x.out sizeof(int) =4 sizeof(long)=8 i = 4294967295 adding 1 withOUT cast = 0 adding 1 WITH cast = 4294967296 Signed-off-by:Tim Sell <Timothy.Sell@unisys.com> Reported-by:
