Detailed Description

struct dw_i2c_dev - private i2c-designware data : driver model device node : IO registers pointer : tx completion indicator : protect this struct and IO registers : input reference clock : run time hadware error code : points to an array of messages currently being transfered : the number of elements in msgs : the element index of the current tx message in the msgs array : the length of the current tx buffer : the current tx buffer : the element index of the current rx message in the msgs array : the length of the current rx buffer : the current rx buffer : error status of the current transfer : i2c master status, one of STATUS_* : copy of the TX_ABRT_SOURCE register : interrupt number for the i2c master : i2c subsystem adapter node : depth of the hardware tx fifo : depth of the hardware rx fifo
