Subject: [PATCH v3 0/4] hw/i2c: Adds pca954x i2c mux switch device
Date: Fri, 9 Apr 2021 13:14:39 -0700 [thread overview]
Message-ID: <20210409201443.111197-1-venture@google.com> (raw)
The i2c mux device pca954x implements two devices:
- the pca9546 and pca9548.
v3:
- fixup comment with missing end parenthesis.
- removed superfluous object cast.
v2:
- the core i2c bus now calls a match method on each i2c child, which
by default will only check for a match against itself.
- the pca954x device overrides the i2c device match method to search
the children for each of its buses that are active.
- the pca954x device now owns an i2c bus for each channel, allowing
the normal device model to attach devices to the channels.
Patrick Venture (4):
hw/i2c: name I2CNode list in I2CBus
hw/i2c: add match method for device search
hw/i2c: move search to i2c_scan_bus method
hw/i2c: add pca954x i2c-mux switch
