Pull MTD updates from Brian Norris:
 "Summary:
   - Add device tree support for DoC3

   - SPI NOR:
        Refactoring, for better layering between spi-nor.c and its
        driver users (e.g., m25p80.c)

        New flash device support

        Support 6-byte ID strings

   - NAND:
        New NAND driver for Allwinner SoC's (sunxi)

        GPMI NAND: add support for raw (no ECC) access, for testing
        purposes

        Add ATO manufacturer ID

        A few odd driver fixes

   - MTD tests:
        Allow testers to compensate for OOB bitflips in oobtest

        Fix a torturetest regression

   - nandsim: Support longer ID byte strings

  And more"

mtd: spi-nor: factor out write_enable() for erase commands

2014-12-01T08:19:03+00:00

write_enable() was being duplicated to both m25p80.c and fsl-quadspi.c.
But this should be handled within the spi-nor abstraction layer.

At the same time, let's add write_disable() after erasing, so we don't
leave the flash in a write-enabled state afterward.

MTD: m25p80: fix inconsistency in m25p_ids compared to spi_nor_ids

2014-11-26T07:09:29+00:00

As stated in a5b7616c5, "mtd: m25p80,spi-nor: Fix module aliases for
m25p80", m25p_ids[] in m25p80.c needs to be kept in sync with
spi_nor_ids[] in spi-nor.c. The change here corrects a misalignment.

(We were missing m25px80 and we had a duplicate w25q128.)

mtd: delete unnecessary checks before two function calls

2014-11-26T06:44:10+00:00

The functions kfree() and pci_dev_put() test whether their argument is NULL
and then return immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

mtd: dataflash: Remove use of tx_dma

2014-11-05T20:57:24+00:00

We are trying to remove the legacy tx_dma and rx_dma fields from the
spi_transfer structure. Currently dataflash uses tx_dma but only to make
sure that it's set to 0 so we can remove this use by replacing with a
zero initialisation of the entire spi_transfer struct.

mtd: spi-nor: fix the wrong dummy value

2014-11-05T08:26:06+00:00

For the DDR Quad read, the dummy cycles maybe 3 or 6 which is less then 8.
The dummy cycles is actually 8 for SPI fast/dual/quad read.

This patch makes preparations for the DDR quad read, it fixes the wrong dummy
value for both the spi-nor.c and m25p80.c.
