In the edma driver, there are couple of instances where braces
are used for a single statement 'if' construct.
There are other instances where 'else' part of the if-else construct
does not use braces even if the 'if' part is a multi-line statement.
This patch fixes both.

'edma_info' structure inside the edma driver represents
a single instance of edma channel controller. Call it
'edma_cc' instead. This also avoids readers confusing
it with an instance of edma_soc_info structre which
carries the platform data for a single channel controller
instance.

This patch implements davinci serial cleanups towards having this code
reusable on tnetv107x.
The change reuses the platform data membase field to hold the remapped space.
By disabling the UPF_IOREMAP flag in the platform data, we prevent
the 8250 driver from repeating the ioremap.

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.

Pinmux registers are sequential, and do not need to be enumerated out as they
currently are. This reduces code volume and keeps things simple.
If some future SoC comes up with a discontiguous register map, PINMUX() can
then be expanded with local token pasting.

This patch allows for gpio controllers that deviate from those found on
traditional davinci socs. davinci_soc_info has an added field to indicate the
soc-specific gpio controller type. The gpio initialization code then bails
out if necessary.
More elements (tnetv107x) to be added later into enum davinci_gpio_type.

This patch renders the inlined gpio accessors in gpio.h independent of the
underlying controller's register layout. This is done by including three new
fields in davinci_gpio_controller to hold the addresses of the set, clear, and
in data registers.
Other changes:
1. davinci_gpio_regs structure definition moved to gpio.c. This structure is
no longer common across all davinci socs (davinci_gpio_controller is).
2. controller base address calculation code (gpio2controller()) moved to
gpio.c as this was no longer necessary for the inline implementation.
3. modified inline range checks to use davinci_soc_info.gpio_num instead of
DAVINCI_N_GPIO.

Renamed gpio types to something more sensible:
struct gpio_controller --> struct davinci_gpio_regs
struct davinci_gpio --> struct davinci_gpio_controller
gpio2controller() --> gpio2regs()
irq2controller() --> irq2regs()
This change also moves davinci_gpio_controller definition to gpio.h.
Eventually, the gpio registers structure will be moved to gpio.c and no longer
a common cross-soc definition.

The IDE platform device is registered in three different places (2 board files
for DM644x and in dm646x.c for DM646x) while both the IDE base address and the
IDE IRQ are the same for both SoCs -- therefore, the proper place for the IDE
platform seems to be in devices.c. Merge the IDE platform data and registration
code and create davinci_init_ide() in place of dm646x_init_ide()...

Currently each DaVinci board file #define's its own version of the EMIFA base
addresses (all named DAVINCI_ASYNC_EMIF_*_BASE), which leads to duplication.
Move these #define's to the SoC specific headers, changing their prefixes from
'DAVINCI' to the 'DM355', 'DM644X', and 'DM646X' since all these base addresses
are SoC specific...
And while at it, rename DM646X_ASYNC_EMIF_DATA_CE0_BASE to
DM646X_ASYNC_EMIF_CS2_SPACE_BASE in order to match the DM646x datasheet.

The current clock control code always gates the clock (PSC state Disable = 2)
on clk_disable(). Some on-chip peripherals (e.g. LCD controller on TNETV107X)
need to be put into SwRstDisable = 0 on clock disable, to maintain
hardware sanity.
This patch extends the davinci_psc_config() arguments to pass in the desired
module state instead of a boolean enable/disable. Further, clk_disable() now
checks for the PSC_SWRSTDISABLE clk flag before selecting the target state.

Host map configuration instructs the interrupt controller to route interrupt
channels to FIQ or IRQ lines. Currently, DA8xx family of devices leave these
registers at their reset-default values.
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.

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).
