[PATCH 0/8] clk: ux500: Fixup smp_twd clk for clk notifiers

[Ulf Hansson]

From: Ulf Hansson <ulf.hansson at linaro.org>

This collection of patches fixup smp_twd clk so clk notifiers can use it
properly.

An armss clk is added which is used from cpufreq driver to update frequency
instead of using the prcmu_set|get_arm_opp API. The smp_twd clk is converted
to a fixed_factor clk with armss clk as parent and with a fixed divider of two.
Therfore it will be updated when armss clk is updated and thus corresponding
notifications will be triggered.

I would prefer if these patches could be merged through Mike Turquette's clk
tree, if he think it seems feasible of course. For the mfd and cpufreq patches
I hope Samuel Ortiz and Rafael J. Wysocki if fine by acking patches. If there
are other preferred way of dealing with this I am happy to change setup.

Do note that, the four below patches have already been sent and most of them
have already been acked/reviewed but not merged. I have included them in this
series to provide full overview for reviewers.

ARM: ux500: Remove cpufreq platform device
mfd: db8500: Provide cpufreq table as platform data
cpufreq: db8500: Register as a platform driver
cpufreq: db8500: Fetch cpufreq table from platform data

Patches are based on Linus Torvalds tree with latest commit as of okt 10.
