We pass a ResetType argument to the Resettable class enter phase method, but we don't pass it to hold and exit, even though the callsites have it readily available. This means that if a device cared about the ResetType it would need to record it in the enter phase method to use later on. Pass the type to all three of the phase methods to avoid having to do that.

This commit adds a passthrough for PMBUS_IC_DEVICE_ID to allow Renesas voltage regulators to return the integrated circuit device ID if they would like to. The behavior is very device specific, so it hasn't been added to the general PMBUS model. Additionally, if the device ID hasn't been set, then the voltage regulator will respond with the error byte value. The guest error message will change slightly for IC_DEVICE_ID with this commit.

2022-06-30hw/i2c: add asynchronous sendKlaus Jensen1-0/+2
Add an asynchronous version of i2c_send() that requires the slave to explicitly acknowledge on the bus with i2c_ack(). The current master must use the new i2c_start_send_async() to indicate that it wants to do an asynchronous transfer. This allows the i2c core to check if the target slave supports this or not. This approach relies on adding a new enum i2c_event member, which is why a bunch of other devices needs changes in their event handling switches.

2022-02-21Kconfig: Add I2C_DEVICES device groupPeter Maydell1-0/+5
Currently there is no way for a board model's Kconfig stanza to say "I have an i2c bus which the user can plug an i2c device into, build all the free-standing i2c devices". The Kconfig mechanism for this is the "device group". Add an I2C_DEVICES group along the same lines as the existing PCI_DEVICES. Simple free-standing i2c devices which a user might plausibly want to be able to plug in on the QEMU commandline should have default y if I2C_DEVICES and board models which have an i2c bus that is user-accessible should use imply I2C_DEVICES to cause those pluggable devices to be built. In this commit we mark only a fairly conservative set of i2c devices as belonging to the I2C_DEVICES group: the simple sensors and RTCs (not including PMBus devices or devices which need GPIO lines to be connected).
