Each channel supports Single/Dual/Quad/Octal mode data transfer (1/2/4/8 bidirectional data lines) i.e. FlexSPI acts as an interface to external devices, maximum 4, each with up to 8 bidirectional data lines. - Tested this driver with mtd_debug(Erase/Write/Read) utility and JFFS2 filesystem mounting and booting on NXP LX2160ARDB[2] and LX2160AQDS targets. LX2160ARDB is having two NOR slave device connected on single bus A i.e. A0 and A1 (CS0 and CS1). LX2160AQDS is having two NOR slave device connected on separate buses one flash on A0 and second on B1 i.e. (CS0 and CS3). Verified this driver on following SPI NOR flashes: Micron, mt35xu512aba[3], [Read - 1 bit mode] Cypress, s25fl512s, [Read - 1/2/4 bit mode] [1] https://www.nxp.com/docs/en/reference-manual/IMXRT1050RM.pdf [2] https://patchwork.kernel.org/project/linux-arm-kernel/list/?series=9721 [3] https://patchwork.ozlabs.org/project/linux-mtd/list/?series=63445 Yogesh Gaur (5): spi: spi-mem: Add driver for NXP FlexSPI controller dt-bindings: spi: add binding file for NXP FlexSPI controller arm64: dts: lx2160a: add FlexSPI node property arm64: defconfig: enable NXP FlexSPI driver MAINTAINERS: add maintainers for the NXP FlexSPI driver Changes for v4: - Incorporated review comments for patch 'spi: spi-mem: Add driver for NXP FlexSPI controller'. - Incorporated binding file review comments of Rob Herring.
