> Subject: [PATCH v4 0/5] spi: spi-mem: Add driver for NXP FlexSPI controller
>
> - Add driver for NXP FlexSPI host controller
>
> FlexSPI is a flexsible SPI host controller [1], Chapter 30 page 1475, which
> supports two SPI channels and up to 4 external devices.
> 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]
