[PATCH RFT 2/2] ARM: dts: mxs: imx28: Fix NAND hierarchy description

[Stefan Wahren]

The size-cells for GPMI are wrong in imx28.dtsi, which causes the
following warning:

    nand-controller@8000c000: #size-cells:0:0: 0 was expected

The reason for this is the definition of the partitions directly
below the nand controller node. According to nand-controller.yaml
the NAND chip must be defined as a child of the controller. Even
the fixed partitions must be kept in a partitions container.

Hi,
unfortunately i don't have access to MSR M28CU3 or an Armadeus Systems APF28
so it would be nice if someone can give a try.

Bindings evolve over time, we sometimes deprecate them when they are
problematic but:
- the old representations are still accepted (but marked legacy)
- if you want to support the new representation you probably need to
  update the controller driver as well (to support both).

In this case I would expect a deprecation notice rather than a pure
error.

Thanks,
Miquèl

i was too naive by assuming that dt-binding and driver are in sync. I 
looked a little bit at the code and DT parsing is done outside of 
gpmi-nand by parsers/ofpart_core. So at least the right part is 
triggered. Unfortunately the parser seems to look at the wrong node.

Unfortunately i don't have a NAND setup to investigate further. Sorry, i 
thought this was a low hanging fruit :-(
