[PATCH 1/5] omap3: overo: Update LCD panel names

[Ash Charles]

From: Adam YH Lee <adam.yh.lee@gmail.com>

For Gumstix Overo COMs, the u-boot bootloader typically passes an
argument specifying the default display via the omapdss.def_disp
parameter.  When a default display is specified, DSS2 tries to match
this name with either the device tree label (e.g. label=dvi) or,
failing this, the device tree alias (e.g. label=display0). Update the
panel names for the 'lcd43' and 'lcd35' displays in the device tree
such that they match the names passed by u-boot.

[PATCH 2/5] omap3: dts: Add DTS for Gumstix TobiDuo expansion board

[Ash Charles]

The Gumstix "Tobi-Duo" expansion board [1] can be used with either
OMAP3 Overo or Overo Storm COMs.  It provides two NICs using LAN9221
chips.
It is necessary to duplicate the interface information for the
second SMSC9221 chip as discussed [2].

[PATCH 3/5] omap3: overo: Enable McBSP2 for all Overo COMs

[Ash Charles]

From: Adam YH Lee <adam.yh.lee@gmail.com>

Both Gumstix Overo and Overo Storm COMs use TWL4030 audio module
connected to the McBSP2.  As such, enable the McBSP2 module in the
common device tree file, omap3-overo-base.dtsi, rather than in the
processor-specific device tree files, omap3-overo.dtsi and
omap3-overo-storm.dtsi.  This corrects audio on the Storm COMs where
the setting was accidentally missing from the device tree.

[PATCH 4/5] omap3: overo: Support PoP NAND

[Ash Charles]

Some Overo COM models include NAND flash in the on-board
package-on-package (PoP) chip.  Add this to the base Overo devicetree.

Most commonly, this is 512MB NAND from the Micron MT29C4G96MAZ family
but, as discussed [1], several different sized are possible. To
support different sizes, the last partition should fill to the end of
the chip (i.e. MTDPART_SIZ_FULL).

With thanks to Florian Vaussard for the original patch [2] and Adam Lee for
updating it here.

Re: [PATCH 1/5] omap3: overo: Update LCD panel names

Applying this one into omap-for-v4.2/fixes thanks.
