phyBOARD-WEGA-AM335x represents a direct soldered
combination of a phyCORE-AM335x SoM and carrier board.

Different kind of SoM options can be connected to
the wega carrier board. So we created a separate
wega dtsi file. The final dts contains the actual
SoM on the carrier board.

WEGA carrier board features:
* ETH phy on carrier board: 1x MII
* 1x CAN
* 2x UART
* USB0 (device)
* USB1 (host)
* mSD slot

phyCORE-AM335x is a SoM (System on Module) containing
a AM335x SOC. The module can be connected to different
carrier boards.

Some hardware parts are configurable on the phyCORE-AM335x.
So they are disabled on default in this som dtsi file.
They will be enabled in the board dts files, when populated.

* RAM up to 1GiB
* PMIC
* NAND flash up to 1GiB
* Eth PHY on SOM: 1x RMII
* SPI NOR flash 8MiB (optional)
* i2c RTC (optional)
* i2c EEPROM 4kiB (optional)

value. the driver use API of_property_read_u16() read the value. For these
u16 value, the dts entry should be like:
	property = /bits/ 16 <0x5000>;
This describes the property as a u16 value.

In addition to the regular mux configuration such as mux mode 1,
2 etc, certain pins of DRA7 require to have "virtual mode" also
programmed. This allows for predefined delay characteristics to
be used by the SoC to meet timing characterstics needed for the
interface.

Provide easy to use macro to do the same.

It is important to note that the official TI guidelines recommend
to do as minimal pin reconfiguration beyond the bootloader given
the design of the hardware involved which can result in substantial
glitches which may impair functionality of certain peripherals.

remove the entry for now.

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.

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.

This reverts commit dec4f799.

Jörg Otte reports a NULL pointder dereference due to this commit, as
'crtc_state' very much can be NULL:

        crtc_state = state->base.state ?
                intel_atomic_get_crtc_state(state->base.state, intel_crtc) : NULL;

So the change to test 'crtc_state->base.active' cannot possibly be
correct as-is.

There may be some other minimal fix (like just checking crtc_state for
NULL), but I'm just reverting it now for the rc2 release, and people
like Daniel Vetter who actually know this code will figure out what the
right solution is in the longer term.
