The purpose of this page is to describe the Linux Zynq QSPI driver for Xilinx QSPI PSIntroduction. This page provides information about the Zynq QSPI driver which can be found on Xilinx Git as spi zynq qspi. Zynq has one QSPI hard IP. This is built on top of Cadence SPI with support for QSPI flash devices, linear read and single, parallel and stacked flash configurations. MTD layer handles all the flash devices used with QSPI. This layer handles flash devices of different makes MicronNumonyx, Winbond and Spansion being the most commonof different sizes from 1. Mbit to 1. Gbit. The features of all flash devices are not alike and hence handled through different flags indicating the support. This layer was customized by xilinx to support parallel and stacked configurations.

Single, parallel and dual stacked modes. Single One flash device is connected using one slave select, one clock and four data lines. Parallel Two flash devices are connected using common slave select and separate data lines. Stacked Two flash devices are connected using separate slave selects and common data lines. Driver uses manual chip select and auto start. Programmable clock frequency, polarity and phase. Interrupt support. Rx bus width of 1 to 4 supports quad read. Tx bus width of 1 to 4 Current support in custom MTD layer is for bus width of 1Support for SPI NOR flash devices of sizes from 1. Mbit to 1. Gbit. Various flash related features supported in customized MTD such as bank selection, lockunlock in single, parallel and stacked modes. Missing Features and known IssuesLimitations in Driver. This driver does not use linear read. In dual parallel mode, all register read responses other than status are obtained only from lower flash device by the controller. Kernel Configuration Options.
