Michael Williamson 336f402790 davinci: mityomapl138: Use auto-probe to determine attached PHY ID
Current board configurations involving the MityDSP-L138 and MityARM-1808
only have one attached PHY, but it's address may not be the same.  Default
the behavior to auto-probe for the PHY and use the first one found.

Michael Williamson ad10e1051e davinci: mityomapl138: Use correct id for NAND controller
For the MityDSP-L138/MityARM-1808 SOMS, the NAND controller id (which needs
to correspond to the chipselect, and is used for controlling the HW ECC
computation) is not correct.  Fix it.

Michael Williamson 6619490a7f davinci: Support various speedgrades for MityDSP-L138 and MityARM-1808 SoMs
For the MityDSP-L138/MityARM-1808 SoMs, the speed grade can be determined
from the part number string read from the factory configuration block on
the on-board I2C PROM.  Configure the maximum CPU speed based on this
information.

This patch was tested using a MityDSP-L138 and MityARM-1808 at various
speedgrades.  Also, for code coverage, a bogus configuration was tested
as well as a configuration having an unknown part number.

Sekhar Nori 8939b3504d davinci: mityomapl138: make file local data static
Most of the regulator data structures are local to the
board file, but not made static. Fix this.

Also make the nand partition table static.

This gets rid of all the sparse warnings for this file.

For the MityDSP-L138/MityARM-1808 SOMS, read the factory assigned
MAC address from the onboard I2C EPROM and assign it to the emac
device during platform initialization.

Cyril Chemparathy 782f2d7827 davinci: cleanup mdio arch code and switch to phy_id
This patch removes davinci architecture code that has now been rendered
useless by the previous patches in the MDIO separation series.

In addition, the earlier phy_mask definitions have been replaced with
corresponding phy_id definitions.

Michael Williamson 8774882394 davinci: Add I2C0 devices to MityDSP-L138/MityARM-1808 platform
This patch adds the i2c0 bus and attached devices to the MityDSP-L138
and MityARM-1808 davinci SoM.  Included is a TPS65023 voltage regulator
needed for power management and a small 24c02 EPROM that contains
factory configuration data.

Michael Williamson f2dbb6d91b davinci: Initial support for MityDSP-L138/MityARM-1808
This patch adds initial support for the MityDSP-L138 and MityDSP-1808 system
on Module (SOM) under the machine name "mityomapl138".  These SOMs are based
on the da850 davinci CPU architecture.  Information on these SOMs may be
found at http://www.mitydsp.com.

Basic support for the console UART, NAND, and EMAC (MII interface) is
included in this patch.
