USP is a general purpose serial port in SiRFSoC, which can work as SPI. the most data flow of USP and pure SPI is same with main differences in registers layout. this patch moves registers layout to private data, and use flags to differentiate other minor differences between prima2-spi, prima2-usp and atlas7-usp for hardware configuration.

there are many SPI clients which use the following protocal: step 1: send command bytes to clients(rx buffer is empty) step 2: send data bytes to clients or receive data bytes from clients. SiRFprimaII provides a shortcut for this kind of SPI transfer. when tx buf is less or equal than 4 bytes and rx buf is null in a transfer, we think it as 'command' data and use hardware command register for the transfer. here we can save some CPU loading than doing both tx and rx for a normal transfer.

2013-09-17spi: bitbang: Let spi_bitbang_start() take a reference to masterAxel Lin
Many drivers that use bitbang library have a leak on probe error paths. This is because once a spi_master_get() call succeeds, we need an additional spi_master_put() call to free the memory. Fix this issue by moving the code taking a reference to master to spi_bitbang_start(), so spi_bitbang_start() will take a reference to master on success. With this change, the caller is responsible for calling spi_bitbang_stop() to decrement the reference and spi_master_put() as counterpart of spi_alloc_master() to prevent a memory leak. So now we have below patten for drivers using bitbang library: probe: spi_alloc_master -> Init reference count to 1 spi_bitbang_start -> Increment reference count remove: spi_bitbang_stop -> Decrement reference count spi_master_put -> Decrement reference count (reference count reaches 0) Fixup all users accordingly.

2013-05-20spi: sirf: fix the issue while transferring more than 256 wordsQipan Li
currently, spi irq handler only does rx processing and fetching data from rx fifo when "FRM_END" irq happens. FRM_END indicates one transfer completes. if rx size is less than 256, it works well. but the problem is that spi rx fifo size is only 256 bytes, then if data size of one frame is more than 256, before FRM_END comes, rx fifo will be filled with RXFIFO_OFLOW overflow interrupt, it will make us lose some data due to fifo overflow. Explicitly we need do fetch work from device rx fifo in irq handler not only in "FRM_END" irq but also in "THD_REACH" irq. THD_REACH means rx fifo has come to its threshold and will come to overflow if we don't take data from it in time. In this patch, we fix this issue. we take data from rx fifo when either FRM_END or RX_THD_REACH irq comes, we put data into tx fifo when either TX_FIFO_EMPTY or TX_THD_REACH irq comes.
