Todd Fischer da1e368032 davinci: da850 TPS6507x touch screen driver board data
The touch screen controller in the TPS6507x chip needs values that are
dependent on the characteristics of the touch screen hardware being used
in the board design.  In addition, the board provides version information
that is exposed via the kernel input sub-system.

Todd Fischer 0bc20bba35 mfd: Add tps6507x board data structure
Add mfd structure which refrences sub-driver initialization data. For example,
for a giving hardware implementation, the voltage regulator sub-driver
initialization data provides the mapping betten a voltage regulator and what
the output voltage is being used for.

Sudhakar Rajashekhara ca2afb6dbe davinci: mmc: pass number of SG segments as platform data
On some platforms like DM355, the number of EDMA parameter slots available
for EDMA_SLOT_ANY usage are few.  In such cases, if MMC/SD uses 16 slots
for each instance of MMC controller, then the number of slots available
for other modules will be very few.

By passing the number of EDMA slots to be used in MMC driver from platform
data, EDMA slots available for other purposes can be controlled.

Most of the platforms will not use this platform data variable.  But on
DM355, as the number of EDMA resources available is limited, the number of
scatter- gather segments used inside the MMC driver can be 8 (passed as
platform data) instead of 16.  On DM355, when the number of scatter-gather
segments was reduced to 8, I saw a performance difference of about
0.25-0.4 Mbytes/sec during write.  Read performance variations were
negligible.

Cyril Chemparathy bcd6a1c695 Davinci: iotable based ioremap() interception
This patch allows for a more flexible ioremap() interception based on iotable
contents.

With this patch, the ioremap() interception code can properly translate
addresses only after davinci_soc_info has been initialized.  Consequently,
in soc-specific init functions, davinci_common_init() has to happen before any
ioremap() attempts. The da8xx init sequence has been suitably modified to meet
this restriction.

Cyril Chemparathy 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.

TNETV107X however does not have sane reset defaults, and therefore this
architecture needs to reconfigure the host-map such that channels 0 and 1
go to FIQ, and the remaining channels raise IRQs.

This patch adds an optional host map argument to cp_intc_init() for this.

Cyril Chemparathy 8ca2e597fc Davinci: enable timer clock before use
timer_init() programs timer64 hardware.  The module should ideally be brought
out of reset before this happens.

Cyril Chemparathy b722049d7e Davinci: allow SOCs based on other ARM CPUs
Preliminary modification prior to adding support for TNETV107X based on
ARM1176.  This change allows for CPUs other than ARM926T to be used for Davinci
derivative SoCs.  Existing devices (DA8x and DMx) operate unchanged.

Anuj Aggarwal a7e05065f5 davinci: edma: clear interrupt status for interrupt enabled channels only
Currently, the ISR in the EDMA driver clears the pending interrupt for all
channels without regard to whether that channel has a registered callback
or not.

This causes problems for devices like DM355/DM365 where the multimedia
accelerator uses EDMA by polling on the interrupt pending bits of some of the
EDMA channels. Since these channels are actually allocated through the Linux
EDMA driver (by an out-of-kernel module), the same shadow region is used by
Linux and accelerator. There a race between the Linux ISR and the polling code
running on the accelerator on the IPR (interrupt pending register).

This patch fixes the issue by making the ISR clear the interrupts only for
those channels which have interrupt enabled. The channels which are allocated
for the purpose of being polled on by the accelerator will not have a callback
function provided and so will not have IER (interrupt enable register) bits set.

Tested on DM365 and OMAP-L137/L138 with audio and MMC/SD (as EDMA users).

Vipin Bhandari d154fed723 davinci: da830/omap-l137 evm: use 8-wire MMC/SD card support
The merge for 2.6.34 brings in 8-bit support to the DaVinci MMC/SD driver.

This patch updates the platform data for DA830/OMAP-L137 EVM to use 8-wire
support available in the driver.

Vipin Bhandari 8ccfd3f074 davinci: da830/omap-l137 evm: add support for GPIO based MMC/SD card detection
The DA830/OMAP-L137 EVM has GPIO based card detection logic, but the current
code does not use it.

Add support for GPIO based card detection to avoid reading the card to see
if a card is present or not.
