Subject: [PATCH 0/2] spi: Add Qualcomm QUP SPI controller support

From: "Ivan T. Ivanov" <iivanov@...sol.com>

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
