21ce873d21 davinci: sparse: gpio: void casting
Cleanup usage of void pointers when using genirq.  genirq API
takes and returns void *, where this GPIO API is using those
as __iomem pointers.

c8e42de6ef davinci: DM365: fix duplicate default IRQ priorities
IRQ 29 has two possible interrupts DDRINT and RTC, but having both in
the default priority table is confusing (and triggers a warning from
sparse.)

This patch removes the lower priority DDRINT from the default priority
table leaving the RTC setting as the default.

bb17ef102b davinci: edma: clear events in edma_start()
This patch fixes an issue where a DMA channel can erroneously process an
event generated by a previous transfer.  A failure case is where DMA is
being used for SPI transmit and receive channels on OMAP L138.  In this
case there is a single bit that controls all event generation from the
SPI peripheral.  Therefore it is possible that between when edma_stop()
has been called for the transmit channel on a previous transfer and
edma_start() is called for the transmit channel on a subsequent transfer,
that a transmit event has been generated.

The fix is to clear events in edma_start().  This prevents false events
from being processed when events are enabled for that channel.

d99c387114 davinci: timers: don't enable timer until clocksource is initialized
On da830, when the same timer is used for clocksource and clockevent,
the timer can be started before the clockevent is
registered/initialzed.  This creates a window where a timer
interrupt might fire before the clockevent handler has been
setup and causes a crash.

This patch moves the actual enable/start of the timer after
the clockevent has ben registered.

5a0e3ad6af include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

the idea is to have both enabled in the same kernel simultaneously. However,
the current soc-core doesn't support simultaneous codecs, once that
support will have added, a patch will be posted to enable both codecs in
the DM365 EVM.

77a92c710b davinci: add CDCE949 support on DM6467 EVM
This patch adds the CDCE949 reference oscillator to
the davinci clock list.

On the DM6467T EVM, the CDCE949 is responsible for
generating the pixel clock for display. On the DM6467
EVM, this pixel clock was being obtained from an
internal source. This is not possible on the DM6467T
EVM because of the presence of a 33MHz oscillator.

The TSIF module also requires the CDCE949 to generate
the data clocks.

The actual clock definitions will be added by patches

5b8972d1b6 davinci: add support for CDCE949 clock synthesizer
This patch adds support for TI's CDCE949 - a clock
synthesizer with 4 PLLs and 9 outputs.

It is used on DM6467 EVM. On the EVM, it generates
clocks required for VPIF, TSIF and Audio modules.

This patch adds it as part of the DaVinci clock framework.

Testing:
The various frequency outputs on Y1 have been tested using
a out-of-tree VPIF video driver supporting HD video.
The register values for Y5 frequency outputs have been
derived from TSIF driver sources in MontaVista LSP kernel,
but actual output has not been tested for lack of TSIF
driver which actually works on the latest kernel.

This patch adds support for registering for suspend-to-RAM
functionality on da850/omap-l138 SoCs.

da850 supports wakeup based on external event and RTC
alarm.

Currently only RTC alarm based wakeup is supported.
Support for wakeup based on external event will be
added as later improvements.

For scheduling an alarm event on RTC some useful code

efc1bb8a6f davinci: add power management support
This patch adds core power management (suspend-to-RAM)
support for DaVinci SoCs.

The code depends on the the "deepsleep" feature to suspend
the SoC and saves power by gating the input clock.

The wakeup can be based on an external event as supported
by the SoC.

Assembly code (in sleep.S) is added to aid gating DDR2
clocks. Code doing this work should not be accessing DDR2.
The assembly code is relocated to SRAM by the code in pm.c

The support has been validated on DA850/OMAP-L138 only
though the code is (hopefully) generic enough that other
SoCs supporting deepsleep feature simply requires SoC
specific code to start using this driver.

Note that all the device drivers don't support suspend/resume
still and are being worked on.

c1978e1dfb davinci: add support for DM6467T EVM
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.

13d5e27a44 davinci: DA850/OMAP-L138: avoid using separate initcall for initializing regulator
Using a device_initcall() for initializing the voltage regulator
on DA850 is not such a good idea because it gets called for all
platforms - even those who do not have a regulator implemented.
This leads to a big fat warning message during boot-up when
regulator cannot be found.

Instead, tie initialization of voltage regulator to cpufreq init.
Define a platform specific init call which in case of DA850 gets
used for initializing the regulator. On other future platforms it
can be used for other purposes.

a6c0f6eca1 davinci: add CPU idle driver
The patch adds support for DaVinci cpu idle driver.

Two idle states are defined:
1. Wait for interrupt
2. Wait for interrupt and DDR self-refresh (or power down)

Some DaVinci SoCs support putting DDR in self-refresh (eg Dm644x, DM6467)
while others support putting DDR in self-refresh and power down (eg DM35x,
DA8xx).

Putting DDR (or mDDR) in power down saves more power than self-refresh.

The patch has been tested on DA850/OMAP-L138 EVM.

When kernel is built with CONFIG_DEBUG_SECTION_MISMATCH=y

observed:

WARNING: vmlinux.o(.text+0xc2a4): Section mismatch in reference

The function da850_evm_setup_nor_nand() references

This is often because da850_evm_setup_nor_nand lacks a __initdata

bae105879f davinci: DA850/OMAP-L138 EVM: implement autodetect of RMII PHY
Implement autodetection of RMII PHY by shifting the decision
to use the RMII PHY to da850_evm_ui_expander_setup() from
da850_evm_init() earlier.

Without this patch, selecting RMII PHY in the UI expander menu
will make the MII PHY unusable even though UI board is not
connected.

The actual configuration and registration of the EMAC device
is delayed to device_initcall() so it happens after the UI card
detection is complete.

A side effect of this patch is the removal of a voilation of
Documentation/SubmittingPatches section 2.2 in function
da850_evm_init()

2206771c43 davinci: RMII support for DA850/OMAP-L138 EVM
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
DA830/OMAP-L137 EVM.
