DM6467T (T for Turbo) is a newer and faster DM6467
part from TI. The new part supports 1080p video and
has the ARM running at 495MHz. More SoC information:
http://focus.ti.com/docs/prod/folders/print/tms320dm6467t.html
Spectrum Digital, Inc has a new EVM for this part.
It is _mostly_ same as the older DM6467 EVM except
for a 33MHz crystal input and THS8200 video encoder
for 1080p support.
The meat of this patch is dedicated to initializing
the crystal frequency from EVM board file.
Additional notes:
I did consider some alternative ways to make the crystal
input board specific including - (1) having board code
initialize the crystal frequency using the first member
of soc_info->cpu_clks array (2) introducing a new ref_clk_rate
member in soc_info structure.
But, the current way seems to be the simplest and least
intruding considering that both the clock array and SoC
info structure are actually private to the SoC file. Also
the fact that davinci_common_init() initializes both the
soc_info and clocks in one go.

This patch supports runtime detection of DA830 UI card and
eliminates the need for DA830_UI config option. Successful
probe of GPIO expander present on the UI card is used to
detect its presence. For this reason, GPIO_PCF857X is auto-
selected when DA830 EVM is configured. In case the UI card
is absent, the probe fails in reasonable time.
As a side effect this patch also gets rid of the voilation

DA850/OMAP-L138 EVM has a RMII Ethernet PHY on the UI daughter card. The PHY
is enabled by proper programming of the IO Expander (TCA6416) ports. Also for
RMII PHY to work, the MDIO clock of MII PHY has to be disabled since both the
PHYs have the same address. This is done via the GPIO2[6] pin. This patch adds
support for RMII PHY.
This patch also adds a menuconfig option to select one or no peripheral
connected to expander. Currently, sub-options in this menu are RMII and no
peripheral.This menuconfig option is similar to the one present for UI card on
DA830/OMAP-L137 EVM.

Add graphics support for the Sharp LCD035Q3DG01 graphical
LCD that's on the User Interface (UI) daughter card of the
DA830/OMAP-L137 EVM.
The LCD shares EMIFA lines with the NAND and NOR devices that
are also on the UI card so those lines are shared via a couple
of muxes. The muxes are controlled by the 'MUX_MODE' line on
the UI card. The 'MUX_MODE' line is controlled by pin P6 of
a pcf8574 i2c expander that's at i2c address 0x3f on UI card.
The i2c expander is controlled using the gpio infrastructure
from the board code using the 'setup()' and 'teardown()'
routines.

Add support for the DA850/OMAP-L138 Evaluation Module (EVM)
from TI. The EVM has User Interface (UI) card which contains
various devices. This UI card can be connected to the base
board. Support for all the devices on the UI card and ones on
the EVM will be added in subsequent patches.
The EVM schematics are not available publicly yet; but should
be available soon.
A new defconfig for this board has been added mainly because
the DA830/OMAP-L137 defconfig forces writethrough cache mode
which is not required on DA850/OMAP-L138.

The da830/omap l137 is a new SoC from TI that is similar
to the davinci line. Since its so similar to davinci,
put the support for the da830 in the same directory as
the davinci code.
There are differences, however. Some of those differences
prevent support for davinci and da830 platforms to work
in the same kernel binary. Those differences are:
1) Different physical address for RAM. This is relevant
to Makefile.boot addresses and PHYS_OFFSET. The
Makefile.boot issue isn't truly a kernel issue but
it means u-boot won't work with a uImage including
both architectures. The PHYS_OFFSET issue is
addressed by the "Allow for runtime-determined
PHYS_OFFSET" patch by Lennert Buytenhek but it
hasn't been accepted yet.
2) Different uart addresses. This is only an issue
for the 'addruart' assembly macro when CONFIG_DEBUG_LL
is enabled. Since the code in that macro is called
so early (e.g., by _error_p in kernel/head.S when
the processor lookup fails), we can't determine what
platform the kernel is running on at runtime to use
the correct uart address.
These areas have compile errors intentionally inserted
to indicate to the builder they're doing something wrong.
A new config variable, CONFIG_ARCH_DAVINCI_DMx, is added
to distinguish between a true davinci architecture and
the da830 architecture.
Note that the da830 currently has an issue with writeback
data cache so CONFIG_CPU_DCACHE_WRITETHROUGH should be
enabled when building a da830 kernel.

Sudhakar Rajashekhara and Sekhar Nori.

features with the aim of DVFS functionality.
Highlights:
- model PLLs and all PLL-derived clocks
- model parent/child relationships of PLLs and clocks
- convert to new clkdev layer
- view clock frequency and refcount via /proc/davinci_clocks
