This patch update the common clock.c file for OMAP4. The clk_get() and clk_put() functions are moved to common place in arch/arm/common/clkdev.c Since on current OMAP4 platform clk management is still not supported, the platform file is stubbed with those functions. Once the framework is ready, this WILL be replaced with a full clkdev implementation. Signed-off-by: NSantosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: NTony Lindgren <tony@atomide.com>

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. Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

This function is race-prone and mistakenly conveys the impression to drivers that it is part of the clock interface. Get rid of it: core code that absolutely needs this can just check clk->usecount. Drivers should not use it at all. linux-omap source commit is 5df9e4adc2f6a6d55aca53ee27b8baad18897c05.

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.

propagate_rate() is recursive, so it makes sense to minimise the amount of stack which is used for each recursion.

debugfs_create_*() returns NULL if an error occurs, returns -ENODEV when debugfs is not enabled in the kernel. Comparing to PATCH v1, because clk_debugfs_init is included in "#if defined CONFIG_DEBUG_FS", we only need to check NULL return.

debugfs can provide the infrastructure to trace the dependencies of clock tree hierarchy quite visibly. This patch enables to keep track of clock tree hierarchy and expose their attributes under each clock directry as below: omap:~# tree -d -L 2 /debug/clock/omap_32k_fck/ /debug/clock/omap_32k_fck/ |-- gpt10_fck |-- gpt11_fck |-- gpt1_fck |-- per_32k_alwon_fck | |-- gpio2_fck | |-- gpio3_fck | |-- gpio4_fck | |-- gpio5_fck | |-- gpio6_fck | `-- wdt3_fck |-- ts_fck `-- wkup_32k_fck |-- gpio1_fck `-- wdt2_fck 14 directories omap:~# tree /debug/clock/omap_32k_fck/gpt10_fck/ /debug/clock/omap_32k_fck/gpt10_fck/ |-- flags |-- rate `-- usecount 0 directories, 3 files Although, compared with David Brownell's small patch, this may look bit overkilling, I expect that this debugfs can deal with other PRCM complexities at the same time. For example, powerdomain dependencies can be expressed by using symbolic links of these clocks if powerdomain supports dubgfs as well.

I recently picked up my older work to remove unnecessary #includes of sched.h, starting from a patch by Dave Jones to not include sched.h from module.h. This reduces the number of indirect includes of sched.h by ~300. Another ~400 pointless direct includes can be removed after this disentangling (patch to follow later). However, quite a few indirect includes need to be fixed up for this. In order to feed the patches through -mm with as little disturbance as possible, I've split out the fixes I accumulated up to now (complete for i386 and x86_64, more archs to follow later) and post them before the real patch. This way this large part of the patch is kept simple with only adding #includes, and all hunks are independent of each other. So if any hunk rejects or gets in the way of other patches, just drop it. My scripts will pick it up again in the next round.
