pmbus: (ibm-cffps) Add support for version 2 of the PSU

2019-09-05T17:42:17+00:00

Version 2 of the PSU supports a second page of data and changes the format of the FW version. Use the devicetree binding to differentiate between the version the driver should use.

hwmon: (lm75) Fixup tmp75b clr_mask

2019-08-16T08:11:09+00:00

commit a95a4f3f2702b55a89393bf0f1b2b3d79e0f7da2 upstream. The configuration register of the tmp75b sensor is 16bit long, however the first byte is reserved, so there is not no need to take care of it. Because the order of the bytes is little endian and it is only necessary to write one byte, the desired bits must be shifted into a 8 bit range.

hwmon: (nct7802) Fix wrong detection of in4 presence

2019-08-16T08:11:08+00:00

commit 38ada2f406a9b81fb1249c5c9227fa657e7d5671 upstream. The code to detect if in4 is present is wrong; if in4 is not present, the in4_input sysfs attribute is still present. In detail: - Ihen RTD3_MD=11 (VSEN3 present), everything is as expected (no bug). - If we have RTD3_MD!=11 (no VSEN3), we unexpectedly have a in4_input file under /sys and the "sensors" command displays in4_input. But as expected, we have no in4_min, in4_max, in4_alarm, in4_beep. Fix is_visible function to detect and report in4_input visibility as expected.

hwmon: (occ) Fix division by zero issue

[ Upstream commit 211186cae14de09573b062e478eb9fe215aed8d9 ] The code in occ_get_powr_avg() invokes div64_u64() without checking the divisor. In case the divisor is zero, kernel gets an "Division by zero in kernel" error. Check the divisor and make it return 0 if the divisor is 0.

hwmon (occ): Add temp sensor value check

2019-07-10T07:30:15+00:00

The occ driver supports two formats for the temp sensor value. The OCC firmware for P8 supports only the first format, for which no range checking or error processing is performed in the driver. Inspecting the OCC sources for P8 reveals that OCC may send a special value 0xFFFF to indicate that a sensor read timeout has occurred, see https://github.com/open-power/occ/blob/master_p8/src/occ/cmdh/cmdh_fsp_cmds.c#L395 That situation wasn't handled in the driver. This patch adds invalid temp value check for the sensor data format 1 and handles it the same way as it is done for the format 2, where EREMOTEIO is reported for this case.
