[PATCH v2 0/7] ARM: dts: lpc32xx: nonfunctional updates to ea3250 and phy3250 dts

[PATCH v2 0/7] ARM: dts: lpc32xx: nonfunctional updates to ea3250 and phy3250 dts

[Vladimir Zapolskiy]

The change updates DTS files of PHY3250 and EA3250 boards powered by
NXP LPC3250 SoC:
* flatten board DTS files by exploiting device node labels,
* add 'partitions' device node for MTD OF,
* correct Atmel vendor prefix,
* rename board DTS files by adding SoC name prefix.

The change is wanted to have to prevent similar issues on copy-paste
in case if more DTS files for LPC32xx boards are submitted.

No functional changes are intended.

Changes from v1 to v2:
* on move of NAND partitions to a 'partitions' subnode added missing
  'compatible = "fixed-partitions";' properties,
* since file renaming closes two subseries of changes, rebased the
  rest on top the changes above,
* added Acked-by tag to the changes acknowledged by Sylvain.

Thanks to Sylvain for review and finding an issue which is
by the way seems to be a checkpatch's false negative.

[PATCH v2 2/7] ARM: dts: lpc32xx: ea3250: add NAND partitions device node

[Vladimir Zapolskiy]

To declare MTD OF partitions NAND controller device node should have
a special 'partitions' subnode, the change removes a debug message
from mtd/ofpart on boot:

  nxp_lpc3220_slc: 'partitions' subnode not found on /ahb/flash at 20020000.
  Trying to parse direct subnodes as partitions.

[PATCH v2 6/7] ARM: dts: lpc32xx: phy3250: add NAND partitions device node

[Vladimir Zapolskiy]

To declare MTD OF partitions NAND controller device node should have
a special 'partitions' subnode, the change removes a debug message
from mtd/ofpart on boot:

  nxp_lpc3220_slc: 'partitions' subnode not found on /ahb/flash at 20020000.
  Trying to parse direct subnodes as partitions.

Signed-off-by: Vladimir Zapolskiy <vz@mleia.com>

* on conversion added missing 'compatible = "fixed-partitions";',
  thanks to Sylvain for finding
