ARM: OMAP: duplicate plat-omap/clock.c into mach-omap[12]/clock.c

2012-10-18T23:22:26+00:00

Duplicate arch/arm/plat-omap/clock.c into arch/arm/mach-omap1/clock.c and arch/arm/mach-omap2/clock.c. This is to support people who are working on the ARM single image kernel and the OMAP common clock framework conversion. Signed-off-by: Paul Walmsley Cc: Tony Lindgren Signed-off-by: Tony Lindgren

ARM: OMAP2+: hwmod: get rid of all omap_clk_get_by_name usage

2012-09-22T16:50:01+00:00

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. 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. Signed-off-by: Rajendra Nayak Cc: Russell King - ARM Linux [paul@pwsan.com: removed IS_ERR_OR_NULL() conversion (rmk comment); restricted omap_96m_alwon_fck_3630 to OMAP36xx; added missing AM35xx clock aliases for emac_fck, emac_ick, vpfe_ick, vpfe_fck; added aliases rng_ick and several emulation clocks] Signed-off-by: Paul Walmsley

ARM: OMAP: PM: Lock clocks list while generating summary

2012-06-17T17:57:50+00:00

Commit a53025724052b2b1edbc982a4a248784638f563d (OMAP: Add debugfs node to show the summary of all clocks) introduced clock summary, however, we are interested in seeing snapshot of the clock state, not in dynamically changing clock configurations as the data provided by clock summary will then be useless for debugging configuration issues. So, hold the common lock when dumping the clock summary.

ARM: OMAP: clock: cleanup CPUfreq leftovers, fix build errors

2012-04-15T00:49:07+00:00

Now that we have OPP layer, and OMAP CPUfreq driver is using it, we no longer need/use the clock framework code for filling up CPUfreq tables. Remove it. Removing this code also eliminates build errors when CPU_FREQ_TABLE support is not enabled. Thanks to Russell King for pointing out the parts I missed under plat-omap in the original version and also pointing out the build errors when CPUFREQ_TABLE support was not enabled.

ARM: OMAP: clock: fix race in disable all clocks

2012-04-04T15:23:34+00:00

clk_disable_unused is invoked when CONFIG_OMAP_RESET_CLOCKS=y. Since clk_disable_unused is called as lateinitcall, there can be more than a few workqueues executing off secondary CPU(s). The current code does the following: a) checks if clk is unused b) holds lock c) disables clk d) unlocks Between (a) and (b) being executed on CPU0, It is possible to have a driver executing on CPU1 which could do a get_sync->clk_get (and increase the use_count) of the clock which was just about to be disabled by clk_disable_unused. We ensure instead that the entire list traversal is protected by the lock allowing for parent child clock traversal which could be potentially be done by runtime operations to be safe as well.
