hwmon/pmbus: (q54sj108a2) The PMBUS_MFR_ID is actually 6 chars instead of 5

2021-06-18T08:02:49Z

[ Upstream commit f0fb26c456a30d6009faa2c9d44aa22f5bf88c90 ] The PMBUS_MFR_ID block is actually 6 chars for q54sj108a2. /sys/bus/i2c/drivers/q54sj108a2_test# iotools smbus_read8 $BUS $ADDR 0x99 0x06 Tested: Devices are able to bind to the q54sj108a2 driver successfully.

hwmon: (pmbus/isl68137) remove READ_TEMPERATURE_3 for RAA228228

2021-06-10T11:41:33Z

[ Upstream commit 2a29db088c7ae7121801a0d7a60740ed2d18c4f3 ] The initial version of the RAA228228 datasheet claimed that the device supported READ_TEMPERATURE_3 but not READ_TEMPERATURE_1. It has since been discovered that the datasheet was incorrect. The RAA228228 does support READ_TEMPERATURE_1 but does not support READ_TEMPERATURE_3.

hwmon: (pmbus/pxe1610) don't bail out when not all pages are active

[ Upstream commit f025314306ae17a3fdaf2874d7e878ce19cea363 ] Certain VRs might be configured to use only the first output channel and so the mode for the second will be 0. Handle this gracefully.

hwmon: (pmbus/max31785) Support revision "B"

2021-02-02T03:46:34Z

There was an issue in how the tach feedbacks of dual rotor fans were reported during any change in fan speeds with revision "A" of the MAX31785. When the fan speeds would transition to a new target speed, the rotor not wired to the TACH input when TACHSEL = 0 would report a speed of 0 until the new target was reached. This has been fixed, resulting in a revision "B" update where the MFR_REVISION of "B" is 0x3061.

hwmon: (pmbus/max16601) Add support for MAX16508

2021-01-29T17:20:33Z

MAX16508 is quite similar to MAX16601, except that it does not support the DEFAULT_NUM_POP register and we thus can not dynamically determine the number of populated phases.

hwmon: (pmbus/ibm-cffps) Set the PMBUS_NO_CAPABILITY flag

2021-01-28T01:44:18Z

Several power supplies supported by the IBM CFFPS driver don't report valid data in the CAPABILITY register. This results in PEC being enabled when it's not supported by the device, and since the automatic version detection might fail, disable use of the CAPABILITY register across the board for this driver.
