There is no need to pass clock name strings in platform_data.
Instead, setup clkdev nodes to have correct ASoC device names.

Ethernet Media Access Controller (EMAC) on da850/omap-l138
supports 10/100 Mbps operation. It also supports Media
Independent Interface (MII) and Reduced Media Independent
Interface (RMII) to physical layer (PHY).
Phy which supports MII is present on the DA850/OMAP-L138
base board and Phy supporting RMII is present on the
UI card. This patch adds support only for the MII Phy.
Support for RMII Phy will be added later.

Add support for the DA850/OMAP-L138 Evaluation Module (EVM)
from TI. The EVM has User Interface (UI) card which contains
various devices. This UI card can be connected to the base
board. Support for all the devices on the UI card and ones on
the EVM will be added in subsequent patches.
The EVM schematics are not available publicly yet; but should
be available soon.
A new defconfig for this board has been added mainly because
the DA830/OMAP-L137 defconfig forces writethrough cache mode
which is not required on DA850/OMAP-L138.
This patch has been boot tested on DA850/OMAP-L138 EVM
using ramdisk as filesystem.

The DA850/OMAP-L138 is a new SoC from TI in the same family as
DA830/OMAP-L137.
Major changes include better support for power management,
support for SATA devices and McBSP (same IP as DM644x).

This patch adds platform data and init function for IDE which could be called
from board specific file to register IDE device.
Note that for 594MHz device the transfer mode is limited to UDMA4 since ideclk
rate is less than 100 MHz, which forces udma_mask in palm_bk3710.c to UDMA4,
while for 729MHz device, it is UDMA5.

This patch takes out IO mapping macros from mach/io.h and puts them in
mach/hardware.h avoiding need to include mach/io.h in various files such as
serial.h, vmalloc.h etc.
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).

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.
Additional generalizations for future SoCs in the da8xx family done by
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).

- 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.

Provide a generic SRAM allocator using genalloc, and vaguely
modeled after what AVR32 uses. This builds on top of the
static CPU mapping set up in the previous patch, and returns
DMA mappings as requested (if possible).
Compared to its OMAP cousin, there's no current support for
(currently non-existent) DaVinci power management code running
in SRAM; and this has ways to deallocate, instead of being
allocate-only.
The initial user of this should probably be the audio code,
because EDMA from DDR is subject to various dropouts on at
least DM355 and DM6446 chips.

Package on-chip SRAM. It's always accessible from the ARM, so
set up a standardized virtual address mapping into a 128 KiB
area that's reserved for platform use.
In some cases (dm6467) the physical addresses used for EDMA are
not the same as the ones used by the ARM ... so record that info
separately in the SOC data, for chips (unlike the OMAP-L137)
where SRAM may be used with EDMA.
Other blocks of SRAM, such as the ETB buffer or DSP L1/L2 RAM,
may be unused/available on some system. They are ignored here.
