Newer revs of da830 silicon have different 'variant' field of the JTAG
id register. Current code only supports rev 1.0 silicon.
This patch adds support for rev1.1 and rev2.0 silicon and updates
the 'name' strings to add a '-' between 'omap' & 'l137' to have
consistent naming with da850/omap-l138.
From Mark Grosen <mgrosen@ti.com>:
"There are currently three silicon revisions for OMAPL137. The JTAG IDs
(DEVIDR register contents) for each silicon revision are shown below:
0x0B7D F02F for silicon revision 1.0
0x8B7D F02F for silicon revision 1.1
0x9B7D F02F for silicon revision 2.0
Corresponding errata documentation will be available in the next few
weeks on the ti.com website."

On this board the OHCI port's power control and over-current signals from
TPS2065 power switch are connected via GPIO1[15] and GPIO2[1] respectively,
so we can implement the DA8xx OHCI glue layer's hooks for overriding the
root hub port's power and over-current status bits.
We also have to properly set up the clocking mode in the CFGCHIP2 register,
so that internal 24 MHz reference clock is fed to the USB 2.0 (MUSB) PHY and
its output is used to clock the USB 1.1 (OHCI) PHY...

The edma_alloc_cont_slots API is used for obtaining a set of
contiguous slots. When we use the "_ANY" option with this
API, by definition of this option it is suppossed to start
looking for a set of contiguous slots starting from slot 64 for
DaVinci SOC's and 32 for DA8xx SOC's. This has been explained in
the API description in the driver itself. So when we use the
"_ANY" option with this API, the slot number passed as
an argument should be a "don't care".
This patch takes care of this condition mentioned above.
When checking to see if the starting slot is a valid number,
it checks to make sure that the "_ANY" option is not used.

The main reason to avoid inclusion of mach/io.h is, when default in/out macros
are overridden by machine specific functions (e.g., in case of PCI I/O), they
result into linker error. An example snippet and error snapshot is listed below.
Following code in mach/io.h:
#define inl(p) my_inl()
static inline unsigned int my_inl(unsigned int addr)
{
if (IS_PCI_IO(addr))
return pci_inl ();
else
return le32_to_cpu(__raw_readl(__typesafe_io(addr)));
}
leads to error:
LD arch/arm/boot/compressed/vmlinux
arch/arm/boot/compressed/misc.o: In function `my_inl':
misc.c:(.text+0x2744): undefined reference to `pci_inl'
make[2]: *** [arch/arm/boot/compressed/vmlinux] Error 1
This is because mach/io.h gets included in arch/arm/boot/compressed/misc.c
through mach/serial.h but pci.c file, which defines 'pci_inl' doesn't get built
into compressed vmlinux.

Support DM365 GPIOs ... primarily by handling non-banked GPIO IRQs:
- Flag DM365 chips as using non-banked GPIO interrupts, using a
new soc_info field.
- Replace the gpio_to_irq() mapping logic. This now uses some
runtime infrastructure, keyed off that new soc_info field,
which doesn't handle irq_to_gpio().
- Provide a new irq_chip ... GPIO IRQs handled directly by AINTC
still need edge triggering managed by the GPIO controller.
DM365 chips no longer falsely report 104 GPIO IRQs as they boot.
Intelligence about IRQ muxing is missing, so for the moment this
only exposes the first eight DM365 GPIOs, which are never muxed.
The next eight are muxed, half with Ethernet (which uses most of
those pins anyway).
Tested on DM355 (10 unbanked IRQs _or_ 104 banked ones) and also
on DM365 (16 unbanked ones, only 8 made available).

Add support for the DA830/OMAP-L137 Evaluation Module (EVM)
from TI. The EVM has User Interface (UI) and Audio cards
that can be connected which contain various devices.
Support for those devices and ones on the EVM will be
added in subsequent patches.

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.

Add basic support for the CPLD on the DM365 EVM board:
- Read SW5 to set up NAND and keypad vs (someday) OneNAND
- Export MMC/SD card detect and writeprotect signals
- LED support (same layout as on DM355 EVM)
- Static config for video input:
* external HD imager precludes MMC1, Ethernet, audio
* else either tvp5146 (SD/default) or tvp7002 (HD)
The video input could actually be switched around dynamically;
change that if/when that's needed (and after those other video
inputs have driver support).

The davinci reset routine, davinci_watchdog_reset(), sets the
TCR register instead of the TGCR register as it should to put
the WDT into its "Initial State".
It also writes the WDTCR register without the proper WDKEY
which is pointless since the register will be write-protected.

- Move queue related mappings to dm<soc>.c
EDMA in DM355 and DM644x has two transfer controllers while DM646x
has four transfer controllers. Moving the queue to tc mapping and
queue priority mapping to dm<soc>.c will be helpful to probe these
mappings from platform device so that the machine_is_* testing will
be avoided.
- add channel mapping logic
Channel mapping logic is introduced in dm646x EDMA. This implies
that there is no fixed association for a channel number to a
parameter entry number. In other words, using the DMA channel
mapping registers (DCHMAPn), a PaRAM entry can be mapped to any
channel. While in the case of dm644x and dm355 there is a fixed
mapping between the EDMA channel and Param entry number.
