2017-12-02iio: adc: stm32: add support for differential channelsFabrice Gasnier1-20/+103
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).

2017-12-02iio: adc: stm32: remove const channel names definitionFabrice Gasnier1-52/+14

2017-12-02iio: adc: ina2xx: Allow setting Shunt Voltage PGA gain and Bus Voltage rangeStefan Brüns1-3/+108
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.

2017-12-02iio: adc: ina2xx: Use LSB specifier instead of divider in configStefan Brüns1-6/+6

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.

2017-11-28staging: unisys: visorbus: address theoretical int overflowsTim Sell1-3/+4
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: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David Kershner <david.kershner@unisys.com> Reviewed-by: David Binder <david.binder@unisys.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2017-11-28staging: imx: use ktime_t for timestampsArnd Bergmann3-20/+20
The imx media driver passes around monotonic timestamps in the deprecated 'timespec' format. This is not a problem for the driver, as they won't overflow, but moving to either timespec64 or ktime_t is preferred. I'm picking ktime_t for simplicity here. frame_interval_monitor() is the main function that changes, as it tries to compare a time interval in microseconds. The algorithm slightly changes here, to avoid 64-bit division. The code previously assumed that the error was at most 32-bit worth of microseconds here, so I'm making the same assumption but add an explicit test for it.
