Detailed Description

struct pl022 - This is the private SSP driver data structure : AMBA device model hookup : vendor data for the IP block : the physical memory where the SSP device resides : the virtual memory where the SSP is mapped : outgoing clock "SPICLK" for the SPI bus : SPI framework hookup : controller-specific data from machine setup : thread struct for message pump : pointer to task for message pump kworker thread : work struct for scheduling work to the message pump : spinlock to syncronise access to message queue : message queue : message pump is busy : message pump is running : Tasklet used in Interrupt Transfer mode : Pointer to current spi_message being processed : Pointer to current spi_transfer : pointer to current clients chip(assigned from controller_state) : the next message in the queue has been examined and it was found that it uses the same chip select as the previous message, so we left it active after the previous transfer, and it's active already. : current position in TX buffer to be read : end position in TX buffer to be read : current position in RX buffer to be written : end position in RX buffer to be written : the type of read currently going on : the type of write currently going on : expected FIFO level : optional channel for RX DMA : optional channel for TX DMA : scattertable for the RX transfer : scattertable for the TX transfer : a dummy page used for driving data on the bus with DMA : current chip select (gpio) : list of chipselects (gpios)
