[GIT PULL] MTD updates for 4.9-rc1

[Brian Norris]

Hi Linus,

I've not been very active this cycle, so these are mostly from Boris,
for the NAND flash subsystem.

The following changes since commit 29b4817d4018df78086157ea3a55c1d9424a7cfc:

  Linux 4.8-rc1 (2016-08-07 18:18:00 -0700)

are available in the git repository at:

MTD updates for 4.9-rc1

NAND:

 * Add the infrastructure to automate NAND timings configuration
 * Provide a generic DT property to maximize ECC strength
 * Some refactoring in the core bad block table handling, to help with
   improving some of the logic in error cases.
 * Minor cleanups and fixes

MTD:

 * Add APIs for handling page pairing; this is necessary for reliably
   supporting MLC and TLC NAND flash, where paired-page disturbance affects
   reliability. Upper layers (e.g., UBI) should make use of these in the near
   future.
