Subject: [Qemu-devel] [PULL 21/24] libqos: i2c: move address into QI2CDevice
Date: Mon, 3 Jun 2019 19:10:40 +0200 [thread overview]
Message-ID: <1559581843-3968-22-git-send-email-pbonzini@redhat.com> (raw)
In-Reply-To: <1559581843-3968-1-git-send-email-pbonzini@redhat.com>
This removes the hardcoded I2C address from the tests. The address
is passed via QOSGraphEdgeOptions to i2c_device_create and stored
in the QI2CDevice.
The i2c_send and i2c_recv functions, along with their wrappers,
therefore, can be changed to take a QI2CDevice rather than an
adapter/address pair.
