b38434145b ARM: davinci: irqs: Correct McASP1 TX interrupt definition for DM646x
McASP1 TX interrupt is 30, not 32 on DM646x DMSoC.

While at it remove the bogus AEMIF interrupt entry from
dm646x_default_priorities[]. AEMIF interrupt on DM6467 is
60 not 30 and the entry for the correct interrupt number
is already present in the same table.

d5fc0e8dd9 ARM: davinci: Remove redundant/unused parameters for edma
The following parameters are no longer needed by the edma driver since the
information can be obtained from the IP's CCCFG register:
n_channel, n_region, n_slot and n_tc.
Remove the initialization of n_cc as well since in this context it has no
meaning. We have separate edma_soc_info struct/eDMA3_CC instance so this
member does not make any sense (and the driver no longer uses it).

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.

The DM6467 and DM6467T EVMs use different reference clock

the SoC code call a public board routine which sets up the reference

Instead, use the clk_set_rate() API to setup the reference clock
frequency to a different value from the board file.

b7f080cfe2 net: remove mm.h inclusion from netdevice.h
Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually).

To prevent mm.h inclusion via other channels also extract "enum dma_data_direction"
definition into separate header. This tiny piece is what gluing netdevice.h with mm.h
via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h".
Removal of mm.h from scatterlist.h was tried and was found not feasible
on most archs, so the link was cutoff earlier.

Hope people are OK with tiny include file.

Note, that mm_types.h is still dragged in, but it is a separate story.

2de5c00ac0 ARM: 6409/1: davinci: map sram using MT_MEMORY_NONCACHED instead of MT_DEVICE
On Davinci SRAM is mapped as MT_DEVICE becasue of the section
mapping pre-requisite instead of intended MT_MEMORY_NONCACHED

Since the section mapping limitation gets fixed with first
patch in this series, the MT_MEMORY_NONCACHED can be used now.

d22960c8bb davinci: add mdio platform devices
This patch adds mdio platform devices on SoCs that have the necessary
hardware.  Clock lookup entries (aliases) have also been added, so that the
MDIO and EMAC drivers can independently enable/disable a shared underlying
clock.  Further, the EMAC MMR region has been split down into separate MDIO
and EMAC regions.

bc3ac9f316 davinci: edma: provide ability to detect insufficient CC info data
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.

This patch implements the following:

 - interrupt initialization uses ioremap() instead of passing a virtual address
   via davinci_soc_info.

 - machine definitions directly point to cp_intc_init() or davinci_irq_init()

 - davinci_intc_type and davinci_intc_base now get initialized in controller
   specific init functions instead of davinci_common_init()

 - minor fix in davinci_irq_init() to use intc_irq_num instead of
   DAVINCI_N_AINTC_IRQ

c78a5bc2e7 Davinci: watchdog reset separation across socs
The earlier watchdog reset mechanism had a couple of limitations.  First, it
embedded a reference to "davinci_wdt_device" inside common code.  This
forced all derived platforms (da8xx and tnetv107x) to define such a device.
This also would have caused problems in including multiple socs in a single
build due to symbol redefinition.

With this patch, davinci_watchdog_reset() now takes the platform device as an
argument.  The davinci_soc_info struct has been extended to include a reset
function and a watchdog platform_device.  arch_reset() then uses these
elements to reset the system in a SoC specific fashion.

If some future SoC comes up with a discontiguous register map, PINMUX() can

IDE IRQ are the same for both SoCs -- therefore,  the proper place for the IDE

code and create davinci_init_ide() in place of dm646x_init_ide()...

f900d552f9 davinci: build list of unused EDMA events dynamically
Currently, the edma_noevent list is passed from platform data.
But on some architectures, there will be many EDMA channels
which will not be used at all. This patch scans all the
platform devices and then builds a list of events which are
not being used. The unused event list will be used to allocate
EDMA channels in case of EDMA_CHANNEL_ANY usage instead of the
edma_noevent being used earlier for this purpose.

This patch is based on David Brownells's suggestion at
http://article.gmane.org/gmane.linux.davinci/15176.
