e4d24ec39c OMAP1: Fix N770 MMC support
Some of the N770's MMC configuration options seem to have been
dropped. This patch adds them back in again.

Note that only the .ocr_mask change was /critical/, but I've added the
.max_freq setting back as well, as the original sources had it. Can
anyone confirm if this is unnecessary?

Secondly, there is support in the original code for a 4wire/higher
speed mode. As I don't have the requisite N770 hardware (I think it
was a rev2 N770?) to test this, I can't really add it back.

c912f7e1ea OMAP1: PM: update and decouple from OMAP2/3 PM core
Update OMAP1-specific PM infrastructure.  This is a sync of what is in
linux-omap for OMAP1.

This mostly de-couples OMAP1 PM from OMAP2/3 PM and renames things
accordingly, and removes omap2/3 specific code from OMAP1 specific
headers.

Original OMAP1 decoupling patch for OMAP PM branch by Paul Walmsley.

8bd2294922 OMAP2/3: PM: push core PM code from linux-omap
This patch is to sync the core linux-omap PM code with mainline.  This
code has evolved and been used for a while the linux-omap tree, but
the attempt here is to finally get this into mainline.

Following this will be a series of patches from the 'PM branch' of the
linux-omap tree to add full PM hardware support from the linux-omap
tree.

Much of this PM core code was written by Jouni Hogander with
significant contributions from Paul Walmsley as well as many others
from Nokia, Texas Instruments and linux-omap community.

b0b5aa3f4c ARM: OMAP: get rid of OMAP_TAG_USB, v2
OMAP_TAGS should vanish soon since they're not generic arm tags.
Most of them can be converted to a platform_data or parsed
from a command line like e.g. serial tag.

For OMAP_TAG_USB we just let boards call omap_usb_init()
passing a pointer to omap_usb_config.

Patch updated by Tony for mainline, basically make
n770 and h4 compile. Also folded in a fix for OSK

8b9dbc16d4 [ARM] omap: arrange for clock recalc methods to return the rate
linux-omap source commit 33d000c99ee393fe2042f93e8422f94976d276ce
introduces a way to "dry run" clock changes before they're committed.
However, this involves putting logic to handle this into each and
every recalc function, and unfortunately due to the caching, led to
some bugs.

Solve both of issues by making the recalc methods always return the
clock rate for the clock, which the caller decides what to do with.

3f0a820c4c [ARM] omap: create a proper tree of clocks
Traditionally, we've tracked the parent/child relationships between
clk structures by setting the child's parent member to point at the
upstream clock.  As a result, when decending the tree, we have had
to scan all clocks to find the children.

Avoid this wasteful scanning by keeping a list of the clock's children.

fed415e48f [ARM] omap: Fix omap1 clock issues
This fixes booting, and is a step toward fixing things properly:

- Make enable_reg u32 instead of u16
  [rmk: virtual addresses are void __iomem *, not u32]
- Get rid of VIRTUAL_IO_ADDRESS for clocks
- Use __raw_read/write instead of omap_read/write for clock registers

This patch adds a bunch of compile warnings until omap1 clock
also uses offsets.

b820ce4e67 [ARM] omap: mcbsp: convert to use fck/ick clocks directly
Rather than introducing a special 'mcbsp_clk' with code behind it in
mach-omap*/mcbsp.c to handle the SoC specifics, arrange for the mcbsp
driver to be like any other driver.  mcbsp requests its fck and ick
clocks directly, and the SoC specific code deals with selecting the
correct clock.

There is one oddity to deal with - OMAP1 fiddles with the DSP clocks
and DSP reset, so we move this to the two callback functions.
