hwmon: (ads7828) Enable internal reference

2016-06-08T01:23:37+00:00

commit 7a18afe8097731b8ffb6cb5b2b3b418ded77c105 upstream. On ads7828 the internal reference defaults to off upon power up. When using internal reference, it needs to be turned on and the voltage needs to settle before normal conversion cycle can be started. Hence perform a dummy read in the probe to enable the internal reference allowing the voltage to settle before performing a normal read. Without this fix, the first read from the ADC when using internal reference always returns incorrect data. Signed-off-by: Akshay Bhat Signed-off-by: Guenter Roeck Signed-off-by: Greg Kroah-Hartman

Enable adm1278 VOUT sampling

2016-06-03T20:51:55+00:00

The reset value of ADM1278 PMON_CONFIG register does not enable VOUT sampling. This patch enables VOUT sampling in ADM1278 PMON_CONFIG register. The patch fixes issue: https://github.com/openbmc/linux/issues/71. Signed-off-by: Yi Li

While building SPI_PXA2XX into the kernel would make the problem disappear, it appears prudent to ensure that the driver is instantiated before accessing its data structures.

hwmon: Create an NSA320 hardware monitoring driver

2016-03-09T02:40:49+00:00

Create a driver to support the hardware monitoring chip present in the Zyxel NSA320 and some of the other Zyxel NAS devices. The driver reads fan speed and temperature from a suitably pre-programmed MCU on the device. Signed-off-by: Adam Baker [groeck: Dropped .owner field initialization] Signed-off-by: Guenter Roeck

hwmon: (adm1275) Add support for ADM1278

2016-03-05T14:36:03+00:00

ADM1278 is mostly compatible to other chips of the same series. Besides the usual difference in coefficients, it supports a temperature sensor, and it can measure both input and output voltage at the same time. Signed-off-by: Guenter Roeck
