Detailed Description

struct pch_spi_data - Holds the SPI channel specific details : The remapped PCI base address : Pointer to the SPI master structure : Reference to work queue handler : Workqueue for carrying out execution of the requests : Wait queue for waking up upon receiving an interrupt. : Status of SPI Transfer : Status flag for message processing : Lock for protecting this structure : SPI Message queue : Status of the SPI driver : Length of data to be transferred in bits per word : Flag showing active transfer : Transmit data count; for bookkeeping during transfer : Receive data count; for bookkeeping during transfer : Buffer for data to be transmitted : Buffer for Received data : The chip number that this SPI driver currently operates on : Reference to the current chip that this SPI driver currently operates on : The current message that this SPI driver is handling : The current transfer that this SPI driver is handling : Reference to the SPI device data structure : platform_device structure : SPI channel number : Status of IRQ registration
