hw/sensor: Add Renesas ISL69259 device model

2022-07-14T14:24:38+00:00

This adds the ISL69259, using all the same functionality as the existing ISL69260 but overriding the IC_DEVICE_ID. Signed-off-by: Peter Delevoryas Reviewed-by: Titus Rwantare Message-Id: <20220701000626.77395-4-me@pjd.dev> Signed-off-by: Cédric Le Goater

hw/sensor: Add IC_DEVICE_ID to ISL voltage regulators

2022-07-14T14:24:38+00:00

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.

hw/i2c: add asynchronous send

2022-06-30T07:21:14+00:00

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.

hw/sensor: add Maxim MAX31785 device

2022-06-30T07:21:13+00:00

MAX31785 is a PMBus compliant 6-Channel fan controller. It supports 6 fan channels, 11 temperature sensors, and 6-Channel ADC to measure the remote voltages. Datasheet can be found here: https://datasheets.maximintegrated.com/en/ds/MAX31785.pdf This initial version of the driver has skeleton and support for the fan channels. Requests for temperature sensors, and ADC Channels the are serviced with the default values as per the datasheet. No additional instrumentation is done. NV Log feature is not supported.

Kconfig: Add I2C_DEVICES device group

2022-02-21T13:30:20+00:00

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).

hw/sensor: Add lsm303dlhc magnetometer device

2022-02-08T10:56:29+00:00

This commit adds emulation of the magnetometer on the LSM303DLHC. It allows the magnetometer's X, Y and Z outputs to be set via the mag-x, mag-y and mag-z properties, as well as the 12-bit temperature output via the temperature property. Sensor can be enabled with 'CONFIG_LSM303DLHC_MAG=y'.

hw/misc: Add Infineon DPS310 sensor model

2021-09-20T06:50:59+00:00

This contains some hardcoded register values that were obtained from the hardware after reading the temperature. It does enough to test the Linux kernel driver. The FIFO mode, IRQs and operation modes other than the default as used by Linux are not modelled.
