[PATCH v4 01/10] spi: Add a driver for the Freescale/NXP QuadSPI controller

2018-11-07 Thread Frieder Schrempf
From: Frieder Schrempf This driver is derived from the SPI NOR driver at mtd/spi-nor/fsl-quadspi.c. It uses the new SPI memory interface of the SPI framework to issue flash memory operations to up to four connected flash chips (2 buses with 2 CS each). The controller does not support generic
