The davinci platform has tried to get support for the EEPROM right,
but failed to get a clean build so far. At the moment, we get
a warning whenever CONFIG_SYSFS is disabled, as that is needed by
EEPROM_AT24:
warning: (MACH_DAVINCI_EVM && MACH_SFFSDR && MACH_DAVINCI_DM6467_EVM && MACH_DAVINCI_DM365_EVM && MACH_DAVINCI_DA830_EVM && MACH_MITYOMAPL138 && MACH_MINI2440) selects EEPROM_AT24 which has unmet direct dependencies (I2C && SYSFS)
Kevin Hilman initially added the 'select' to ensure that EEPROM_AT24
is always enabled in machines that really want it for normal operation
(i.e. for reading the MAC address). This broke when I2C was disabled,
and Russell King followed up with another patch to select that as
well.
I now see that the SYSFS dependency is still missing, which leaves
us with three options:
a) add 'select SYSFS' in addition to the others
b) change AT24_EEPPROM to work without sysfs (should be possible)
c) remove all those selects again and get the files to build when
I2C is disabled.
I would really hate to do a) because adding select statements that
hardwire user-selectable symbols is generally a bad idea. I first
tried b) but then ended up redoing the patch from scratch to approach
c), so we can also remove the other selects.
I checked that CONFIG_I2C is still enabled with davinci_all_defconfig,
so that does not have to change.

We already forbid that combination when AUTO_ZRELADDR is disabled,
for the same reason that the two have their RAM at different
physical addresses as seen from the CPU.
This does the same change for PATCH_PHYS_VIRT: if you disable
either of the options, Kconfig now enforces that you have to
pick one or the other SoC family.

When da8xx-dt.c is built with onlu DA830 support but not DA850
support enabled, we get a compiler warning about unused symbols:
arch/arm/mach-davinci/da8xx-dt.c:28:20: warning: 'da8xx_init_irq' defined but not used [-Wunused-function]
static void __init da8xx_init_irq(void)

static struct of_dev_auxdata da850_auxdata_lookup[] __initdata = {
Obviously none of the file make sense for DA830, so we should not
even attempt this, so we can avoid the warning by ensuring it is
only built for 850, not 830.

The DA830 chip only works if the dcache is in writethrough mode,
but that produces a harmless Kconfig warning if the cache happens
to be disabled:
warning: (ARCH_DAVINCI_DA830) selects CPU_DCACHE_WRITETHROUGH which has unmet direct dependencies ((CPU_ARM740T || CPU_ARM920T || CPU_ARM922T || CPU_ARM925T || CPU_ARM926T || CPU_ARM940T || CPU_ARM946E || CPU_ARM1020 || CPU_FA526) && !CPU_DCACHE_DISABLE)
This makes the select conditional so we don't have to worry
about the warning in randconfig builds any more.

Now that we have wlcore device-tree bindings in place
(for both wl12xx and wl18xx), remove the legacy
wl12xx_platform_data struct, and move its members
into the platform device data (that is passed to wlcore)
Davinci 850 is the only platform that still set
the platform data in the legacy way (and doesn't
have DT bindings), so remove the relevant
code/Kconfig option from the board file (as suggested
by Sekhar Nori)
Since no one currently uses wlcore_spi, simply remove its
platform data support (DT bindings will have to be added
if someone actually needs it)

The davinci DA8xx and DMx families have incompatible zreladdr
settings, and attempting to build a kernel with both enabled
results in an error unless AUTO_ZRELADDR is set:
multiple zreladdrs: 0xc0008000 0x80008000
This needs CONFIG_AUTO_ZRELADDR to be set
This patch changes Kconfig to make the two families mutually
exclusive when this is unset.

This config exists entirely to hide the cpufreq menu from the
kernel configuration unless a platform has selected it. Nothing
is actually built if this config is 'Y' and it just leads to more
patches that add a select under a platform Kconfig so that some
other CPUfreq option can be chosen. Let's remove the option so
that we can always enable CPUfreq drivers on ARM platforms.

The DAVINCI_DA850_EVM board uses an unusual method to
enable the GPIO_PCA953X and KEYBOARD_GPIO_POLLED symbols,
which leads to the dependencies on these symbols being
ignored. As GPIO_PCA953X actually requires I2C, that
can lead to build failures when I2C is disabled.
This patch removes the duplicate symbol definitions
and instead enables them from the davinci_all_defconfig
file.
A different question whether we actually want to automatically
enable them at all or rather put them into defconfig,
but that should be a separate patch.

The tnetv107x support does not compile, and seems to have been broken
for a while with nobody caring to fix it. So far everyone I asked
said it's probably dead and completely unused and will never again
be needed in a future kernel release, so let's delete it.
If someone finds a use for this code later and is able to get it
to work again, we can always revert the removal.

As suggested by Andrew Morton:
This is a pet peeve of mine. Any time there's a long list of items
(header file inclusions, kconfig entries, array initalisers, etc) and
someone wants to add a new item, they *always* go and stick it at the
end of the list.
Guys, don't do this. Either put the new item into a randomly-chosen
position or, probably better, alphanumerically sort the list.
lets sort all our select statements alphanumerically. This commit was
created by the following perl:
while (<>) {
while (/\\\s*$/) {
$_ .= <>;
}
undef %selects if /^\s*config\s+/;
if (/^\s+select\s+(\w+).*/) {
if (defined($selects{$1})) {
if ($selects{$1} eq $_) {
print STDERR "Warning: removing duplicated $1 entry\n";
} else {
print STDERR "Error: $1 differently selected\n".
"\tOld: $selects{$1}\n".
"\tNew: $_\n";
exit 1;
}
}
$selects{$1} = $_;
next;
}
if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or
/^endif/ or /^endchoice/)) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
undef %selects;
}
print;
}
if (%selects) {
foreach $k (sort (keys %selects)) {
print "$selects{$k}";
}
}
It found two duplicates:
Warning: removing duplicated S5P_SETUP_MIPIPHY entry
Warning: removing duplicated HARDIRQS_SW_RESEND entry
and they are identical duplicates, hence the shrinkage in the diffstat
of two lines.

TNETV107X is a Texas Instruments SOC that shares a number of common features
with the Davinci architecture. Some of the key differences between
traditional Davincis and this new SOC are as follow:
1. The SOCs clock architecture includes a new spread-spectrum PLL. Some
elements of the clock architecture are reused from Davinci (e.g. LPSC), but
the PLL related code is overridden using existing interfaces in "struct clk".
2. The MMR layout on this SOC is substantially different from Davinci.
Consequently, the fixed I/O map is a whole lot more convoluted (more so than
DA8xx). The net impact here is that IO_ADDRESS() will not work on this SoC,
and therefore all mappings have to be through ioremap().

DM6467T (T for Turbo) is a newer and faster DM6467
part from TI. The new part supports 1080p video and
has the ARM running at 495MHz. More SoC information:
http://focus.ti.com/docs/prod/folders/print/tms320dm6467t.html
Spectrum Digital, Inc has a new EVM for this part.
It is _mostly_ same as the older DM6467 EVM except
for a 33MHz crystal input and THS8200 video encoder
for 1080p support.
The meat of this patch is dedicated to initializing
the crystal frequency from EVM board file.
Additional notes:
I did consider some alternative ways to make the crystal
input board specific including - (1) having board code
initialize the crystal frequency using the first member
of soc_info->cpu_clks array (2) introducing a new ref_clk_rate
member in soc_info structure.
But, the current way seems to be the simplest and least
intruding considering that both the clock array and SoC
info structure are actually private to the SoC file. Also
the fact that davinci_common_init() initializes both the
soc_info and clocks in one go.

DA850/OMAP-L138 EVM has a RMII Ethernet PHY on the UI daughter card. The PHY
is enabled by proper programming of the IO Expander (TCA6416) ports. Also for
RMII PHY to work, the MDIO clock of MII PHY has to be disabled since both the
PHYs have the same address. This is done via the GPIO2[6] pin. This patch adds
support for RMII PHY.
This patch also adds a menuconfig option to select one or no peripheral
connected to expander. Currently, sub-options in this menu are RMII and no
peripheral.This menuconfig option is similar to the one present for UI card on

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).
DA850/OMAP-L138 documents are available at
http://focus.ti.com/docs/prod/folders/print/omap-l138.html.

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.

Kconfig entries default to n, so there's no need for this to be

Integrate the Common Platform Interrupt Controller (cp_intc)
support into the low-level irq handling for davinci and similar
platforms. Do it such that support for cp_intc and the original
aintc can coexist in the same kernel binary.
