"struct davinci_uart_config" was introduced to specify
UART ports brought out or enabled on the board. But
none of the boards use it for that purpose and we are
not going to add anymore board files, so remove the
structure.

For modules having single clock, clk_get should be done with dev_id.
But current davinci implementation handles multiple instances
of the UART devices with single platform_device_register. Hence clk_get
is based on con_id rather than dev_id, this is not correct. Do
platform_device_register for each instance and clk_get on dev_id.

Adds support for parsing the TI EDMA DT data into the required EDMA
private API platform data. Enables runtime PM support to initialize
the EDMA hwmod. Enables build on OMAP.
Changes by Joel:
* Setup default one-to-one mapping for queue_priority and queue_tc
mapping as discussed in [1].
* Split out xbar stuff to separate patch. [1]
* Dropped unused DT helper to convert to array
* Fixed dangling pointer issue with Sekhar's changes

Remove specifying mmc controller IP version information via platform
data, instead specify device name so that driver derives it from
platform_device_id table. Also change the clock node name to match
the changed dev_id.
Tested on da850-evm to make sure driver loads without clk_get failures.

In case of error, the function clk_get() returns ERR_PTR() not
NULL pointer. The NULL test in the error handling should be
replaced with IS_ERR().

Davinci platforms may define a default queue for each channel
controller. If one is not defined, the default queue is set to EVENTQ_1.
However, there's no way to distinguish between an unset default queue to
one that is set to EVENTQ_0, as EVENTQ_0 = 0.
Explicitly specify the default queue for all channel controllers on all
Davinci platforms to EVENTQ_1, and don't overwrite it in the EDMA probe
function.
One exception is the DA850 board, for which EVENTQ_1 is not a valid
option for its second channel controller. Use EVENTQ_0 instead for that
channel controller.

This patch modifies the EDMA driver to expect the channel
controller (CC) infomation passed on by the platform as a fixed
size (EDMA_MAX_CC) array of pointers to structures.
Doing so helps catch errors of the sort where the resource
structure has information for more channel controllers than
the number channel controller info structures defined.
Such insufficient platform data would lead to illegal memory
accesses.

TNETV107X is a Texas Instruments SOC that shares a number of common features
with the Davinci architecture. Some of the key differences between
traditional Davincis and this new SOC are as follow:
1. The SOCs clock architecture includes a new spread-spectrum PLL. Some
elements of the clock architecture are reused from Davinci (e.g. LPSC), but
the PLL related code is overridden using existing interfaces in "struct clk".
2. The MMR layout on this SOC is substantially different from Davinci.
Consequently, the fixed I/O map is a whole lot more convoluted (more so than
DA8xx). The net impact here is that IO_ADDRESS() will not work on this SoC,
and therefore all mappings have to be through ioremap().
