This patch series contains fixes and improvements to PMBus support in QEMU.
The following has been added:
- Support for block receive
- Support for devices with fans
- Support for the VCAP register for devices with onboard energy storage
- A bitfield struct for the vout mode register, whose bits determine the
formatting of several read commands in PMBus
Fixes:
- String read now handles now logs an error when passed an empty string
This series is in preparation for some additional sensors that exercise
this functionality that will be incoming shortly.
Changes in v4:
- Added missing commit tags
Changes in v3:
- Added fixes to PMBus: page resets and fault clearing
Changes in v2:
- Expanded commit descriptions
- Added the ADM1266 device model that uses new functions
