[PATCH 0/4] m25p80 Quad/Dual updates

[Geert Uytterhoeven]

	Hi,

This patch series allows to really use Quad and Dual SPI Read Tranfers
with the m25p80 driver:
    [1/4] mtd: m25p80: Enable Quad SPI read transfers for s25fl512s
    [2/4] mtd: m25p80: Set rx_nbits for Quad SPI transfers
    [3/4] mtd: m25p80: Add dual read support
    [4/4] mtd: m25p80: Enable Dual SPI read transfers for s25fl256s1 and
	  s25fl512s

Patch [2/4] is a bug fix.
Patches [3/4] and [4/4] may be considered of limited use (why use Dual
transfers if you have Quad transfers?), but
  1. not all Quad-capable devices may be connected using 6 wires,
  2. it allows to test Dual SPI transfers in SPI master drivers.

This was tested with a preliminary version of the Renesas QSPI driver and a
Spansion s25fl512s SPI FLASH.

Thanks for your comments!
