  To: paul, mturquette, mturquette; +Cc: linux-arm-kernel, linux-omap, Rajendra Nayak

Changes in v2:
* Dropped all driver clk_prepare/clk_unprepare changes, will be
  sent seperately to respective lists

This is a preparatory series for the OMAP Common Clk
conversion. They mostly add clk_prepare/clk_unprepare
in OMAP platform code. Also gets rid of omap_clk_get_by_name
and uses clk_get, and removes all direct 'struct clk'
dereferrencing and uses helpers similar to what is provided
by Common Clk.

Patches are boot tested on OMAP2430sdp, 3630 Beagle-Xm
and 4430/4460 Panda and suspend tested on 3630 Beagle-Xm
and 4430 Panda. Patches apply on 3.5-rc4.

* [PATCH v2 1/3] ARM: omap: clk: add clk_prepare and clk_unprepare
  2012-06-27  8:48 ` Rajendra Nayak

As part of Common Clk Framework (CCF) the clk_enable() operation
was split into a clk_prepare() which could sleep, and a clk_enable()
which should never sleep. Similarly the clk_disable() was
split into clk_disable() and clk_unprepare(). This was
needed to handle complex cases where in a clk gate/ungate
would require a slow and a fast part to be implemented.
None of the clocks below seem to be in the 'complex' clocks
category and are just simple clocks which are enabled/disabled
through simple register writes.
Most of the instances also seem to be called in non-atomic
context which means its safe to move all of those from
using a clk_enable() to clk_prepare_enable() and clk_disable() to
clk_disable_unprepare().
For a few others where there is a possibility they get called from
an interrupt or atomic context, there is an additonal clk_prepare()
done before a clk_enable() and a clk_unprepare()
after a clk_disable().
This is in preparation of OMAP moving to CCF.

Based on initial changes from Mike turquette.

* [PATCH v2 2/3] ARM: omap: hwmod: get rid of all omap_clk_get_by_name usage

  To: paul, mturquette, mturquette; +Cc: linux-arm-kernel, linux-omap, Rajendra Nayak

Moving to Common clk framework for OMAP would mean we no longer use
internal lookup mechanism like omap_clk_get_by_name().
get rid of all its usage mostly from hwmod and omap_device
code.

Also use IS_ERR_OR_NULL() for error checking.

Moving to clk_get() also means the respective platforms
need the clkdev tables updated with an entry for all clocks
used by hwmod to have clock name same as the alias.

Based on original changes from Mike Turquette.

* [PATCH v2 2/3] ARM: omap: hwmod: get rid of all omap_clk_get_by_name usage
@ 2012-06-27  8:48   ` Rajendra Nayak

From: Rajendra Nayak @ 2012-06-27  8:48 UTC (permalink / raw)
  To: linux-arm-kernel

Moving to Common clk framework for OMAP would mean we no longer use
internal lookup mechanism like omap_clk_get_by_name().
get rid of all its usage mostly from hwmod and omap_device
code.

Also use IS_ERR_OR_NULL() for error checking.

Moving to clk_get() also means the respective platforms
need the clkdev tables updated with an entry for all clocks
used by hwmod to have clock name same as the alias.

Based on original changes from Mike Turquette.

* [PATCH v2 3/3] ARM: omap: clk: Remove all direct dereferencing of struct clk
  2012-06-27  8:48 ` Rajendra Nayak

  To: paul, mturquette, mturquette; +Cc: linux-arm-kernel, linux-omap, Rajendra Nayak

While we move to Common Clk Framework (CCF), direct deferencing of struct
clk wouldn't be possible anymore. Hence get rid of all such instances
in the current clock code and use macros/helpers similar to the ones that
are provided by CCF.

* [PATCH v2 3/3] ARM: omap: clk: Remove all direct dereferencing of struct clk
@ 2012-06-27  8:48   ` Rajendra Nayak
  0 siblings, 0 replies; 22+ messages in thread
From: Rajendra Nayak @ 2012-06-27  8:48 UTC (permalink / raw)
  To: linux-arm-kernel

While we move to Common Clk Framework (CCF), direct deferencing of struct
clk wouldn't be possible anymore. Hence get rid of all such instances
in the current clock code and use macros/helpers similar to the ones that
are provided by CCF.

This patch generates quite a few checkpatch warnings:

WARNING: please, no space before tabs
#294: FILE: arch/arm/mach-omap2/clock3xxx_data.c:3479:
+^ICLK(NULL, ^I"mcbsp4_ick",^I&mcbsp2_ick,^ICK_3XXX),$

etc.  

Please fix these.

The 80 column warnings from checkpatch on the CLK(... lines can be 
ignored.

These warnings were actually generated by patch 2/3, not this one.  Sorry

This patch generates checkpatch warnings.  Here's a sample:

In the case of the quoted string warnings, please go ahead and
concatenate those strings while you are there.  That needs to be done

Sorry, I seemed to have overlooked these thinking all to be 80 column
warnings. Will fix all the non 80 column warnings and repost.

Sorry, I seemed to have overlooked these thinking all to be 80 column
warnings. Will fix all the non 80 column warnings and repost.

Ok, will do. I was able to fix all but one hard to fix CHECK for this
patch..

CHECK: Alignment should match open parenthesis
#608: FILE: arch/arm/mach-omap2/dpll3xxx.c:455:
+	if (__clk_get_rate(dd->clk_bypass) == rate &&
  	    (clk->dpll_data->modes & (1 << DPLL_LOW_POWER_BYPASS))) {

total: 0 errors, 0 warnings, 1 checks, 608 lines checked

0003-ARM-omap-clk-Remove-all-direct-dereferencing-of-stru.patch has 
style problems, please review.

If any of these errors are false positives, please report

I could not find anything wrong with the alignment, but checkpatch
keeps complaining. It complains for the original code too.
Might be a checkpatch bug? Or do you really see anything wrong in
the alignment?

Does seem like a checkpatch issue to me, checkpatch -f on the file
after applying the patch does not throw me the 'CHECK' anymore.
Will ignore this for now and respin my v3 and report this to the
checkpatch folks.
