Subject[PATCH 0/2] spi: Add Qualcomm QUP SPI controller support
Date
From: "Ivan T. Ivanov" <iivanov@mm-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
