Russell King 2d34e50729 clkdev: get rid of redundant clk_add_alias() prototype in linux/clk.h
clk_add_alias() is provided by clkdev, and is not part of the clk API.
Howver, it is prototyped in two locations: linux/clkdev.h and
linux/clk.h.  This is a mess.  Get rid of the redundant and unnecessary
version in linux/clk.h.

Stratos Karafotis 499f8ad5ab ARM: davinci: da850: Use cpufreq_for_each_entry macro for iteration
The cpufreq core now supports the cpufreq_for_each_entry macro helper
for iteration over the cpufreq_frequency_table, so use it.

It should have no functional changes.

Manjunathappa, Prakash 19955c3d74 ARM: davinci: uart: move to devid based clk_get
For modules having single clock, clk_get should be done with dev_id.
But current davinci implementation handles multiple instances
of the UART devices with single platform_device_register. Hence clk_get
is based on con_id rather than dev_id, this is not correct. Do
platform_device_register for each instance and clk_get on dev_id.

Viresh Kumar 5070158804 cpufreq: rename index as driver_data in cpufreq_frequency_table
The "index" field of struct cpufreq_frequency_table was never an
index and isn't used at all by the cpufreq core.  It only is useful
for cpufreq drivers for their internal purposes.

Many people nowadays blindly set it in ascending order with the
assumption that the core will use it, which is a mistake.

Rename it to "driver_data" as that's what its purpose is. All of its
users are updated accordingly.

Ido Yariv 6836989c35 ARM: davinci: DA850: Add GPIO pinmux configuration for wl1271
The wl1271 daughter board makes use of a few GPIOs:
GPIO6_9 is used for powering down/up the WLAN functionality.
GPIO6_10 is used as an input IRQ line from the WLAN chip.

Add the required pinmux configuration for these GPIOs.

Sekhar Nori cbb2c9617a davinci: da850: add support for SATA interface
Add support for SATA controller on the
DA850/OMAP-L138/AM18x devices.

The patch adds the necessary clocks, platform
resources and a routine to initialize the SATA
controller.

The PHY configuration in this patch is
courtesy the work done by Zegeye Alemu,
Swaminathan and Mansoor Ahamed from TI.

While testing this patch, enable port multiplier
support iff you are actually using one. The
reasons of this behaviour are discussed
here: http://patchwork.ozlabs.org/patch/78163/

ChangeLog:
v3:
Removed fields which were being initialized
to zero in PHY configuration. Moved SATA base
address definition to the top of the file to
make it inline with what is done for the rest
of the modules.
v2:
Addressed comments from Sergei. Removed unnecessary
braces and removed unnecessary else after goto.

Sudhakar Rajashekhara cbb691fb89 davinci: Add additional JTAG code for AM-1808 and OMAP-L138 Rev 2.0 SoCs
From: Sudhakar Rajashekhara <sudhakar.raj@ti.com>

The JTAG variant code for Rev-2.0 silicon of the OMAP-L138 has changed.
In addition, the variant code for the AM-1808 SoC appears to match
the Rev-2.0 code for the OMAP-L138.  Add an additional entry to support
these chips.

This patch is originally from a patch on the arago project, here:
http://arago-project.org/git/projects/?p=linux-omapl1.git;a=commit;h=6157618435e313a444cdf059702bd34036a6e2b7

Further information related to the need for this patch can be located at
http://e2e.ti.com/support/embedded/f/354/p/67290/248486.aspx
http://linux.davincidsp.com/pipermail/davinci-linux-open-source/2010-November/021224.html

This patch was tested using an AM-1808 SoC on a MityARM-1808 SoM card.  It
was also tested using a Rev 1.0 silicon OMAP-L138 on a MityDSP-L138F card.

Sekhar Nori 39e1455004 davinci: am18x/da850/omap-l138: add support for higher speed grades
AM18x/DA850/OMAP-L138 SoCs have variants that can operate
at a maximum of 456 MHz at 1.3V operating point. Also the
1.2V operating point has a variant that can support a maximum
of 375 MHz.

This patch adds three new OPPs (456 MHz, 408 MHz and 372 MHz)
to the list of DA850 OPPs.

Not all silicon is qualified to run at higher speeds and
unfortunately the maximum speed the chip can support can only
be determined from the label on the package (not software
readable).

Because of this, we depend on the maximum speed grade information
to be provided to us in some board specific way. The board informs
the maximum speed grade information by setting the da850_max_speed
variable.
