Eddie James	e5befc024c	hwmon: (pmbus) Add a PMBUS_NO_CAPABILITY platform data flag ... Some PMBus chips don't respond with valid data when reading the CAPABILITY register. Add a flag that device drivers can set so that the PMBus core driver doesn't use CAPABILITY to determine it's behavior.

Guenter Roeck	9e347728c4	hwmon: (pmbus) Detect if chip is write protected ... If a chip is write protected, we can not change any limits, and we can not clear status flags. This may be the reason why clearing status flags is reported to not work for some chips. Detect the condition in the pmbus core. If the chip is write protected, set limit attributes as read-only, and set the flag indicating that the status flag should be ignored.
