Hi,
Following two patches are adding initial support for SPI controller available in Qualcomm SoC's.
Controller initialization is based on spi_qsd driver available in CAF repository.
Controller supports SPI_CPOL | SPI_CPHA | SPI_CS_HIGH | SPI_LOOP modes, up to 3 CS's and from 4 to 32 bits per word. SPI_LOOP mode is limited to input FIFO buffer size.
Currently driver support only PIO mode, I am hopping to add also DMA mode support with dmaengine patches developed by Andy.
Regards, Ivan
