* spi: iproc-qspi: Add Broadcom iProc SoCs supportKamal Dasu2016-09-241-1/+33
| | | | | | | | | | | This spi driver uses the common spi-bcm-qspi driver and implements iProc SoCs specific interrupt controller. The common driver now calls the SoC handlers when present. Adding support for both muxed l1 and unmuxed interrupt sources.

* spi: bcm-qspi: Add BSPI spi-nor flash controller driverKamal Dasu2016-09-141-0/+20
| | | | | | | | | | | | This change implements BSPI driver for Broadcom BRCMSTB, NS2, NSP SoCs works in combination with the MSPI controller driver and implements flash read acceleration and implements the spi_flash_read() method. Both MSPI and BSPI controllers are needed to access spi-nor flash.

* spi: bcm-qspi: Add Broadcom MSPI driverKamal Dasu2016-09-141-0/+63
Master SPI driver for Broadcom settop, iProc SoCs. The driver is used for devices that use SPI protocol on BRCMSTB, NSP, NS2 SoCs. SoC platform driver call exported porbe(), remove() and suspend/resume pm_ops implemented in this common driver.
