[PATCH v2 0/2] mtd: Add NAND ECC devicetree binding

[Ezequiel Garcia]

Finally we collect an ack from a devicetree authority (thanks Grant) so
this is the second round to add a suitable ECC devicetree binding.

NAND controllers have special ECC modes, raising per-driver ECC mode devicetree
binding. See for instance the binding for OMAP:

 - ti,nand-ecc-opt: A string setting the ECC layout to use. One of:
	"sw"		<deprecated> use "ham1" instead
	"hw"		<deprecated> use "ham1" instead
	"hw-romcode"	<deprecated> use "ham1" instead
	"ham1"		1-bit Hamming ecc code
	"bch4"		4-bit BCH ecc code
	"bch8"		8-bit BCH ecc code

Other drivers (such as pxa3xx-nand) have similar requirements, with special
(controller-specific) ECC modes. Instead of adding a possibly different
binding per compatible-string, let's add generic ECC strength and ECC step size.

This properties aim at providing a complete description of the required ECC
correction to let drivers choose the appropriate ECC mode.

Ezequiel Garcia (2):
  of_mtd: Add helpers to get ECC strength and ECC step size
  mtd: nand: Add a devicetree binding for ECC strength and ECC step size
