WebPMBus is similar to SMBus, in fact it uses part of the SMBus spec as its base. The Transport Layer of PMBus is SMBus 1.1 with extensions and exceptions. Extensions: Block Write-Block Read Process Call Host Notify Protocol Group Command Protocol Extended Command Bus Speed 400Khz with timing modifications Electrical drive levels Exceptions: WebDriver is using the pmbus_core, creating sysfs files under hwmon for inputs: vh1->vh4 and vp1->vp13. 1. Add PMBus probing driver for inputs vh1->vh4 and vp1->vp13. 2. Add Block WR command. A pmbus specific implementation was required because block write with I2C_SMBUS_PROC_CALL flag allows a maximum of 32 bytes to be received. 3.
