When doing module loading verification tests (for example, with module
singing, or LSM hooks), it is very handy to have a module that can be
built on all systems under test, isn't auto-loaded at boot, and has
no device or similar dependencies. This creates the "test_module.ko"
module for that purpo

clk_unregister() is currently not implemented and it is required when
a clock provider module needs to be unloaded.
Normally the clock supplier module is prevented to be unloaded by
taking reference on the module in clk_get().
For cases when the clock supplier module deinitializes despite the

This patch adds common __clk_get(), __clk_put() clkdev helpers that
replace their platform specific counterparts when the common clock
API is used.
The owner module pointer field is added to struct clk so a reference
to the clock supplier module can be taken by the clock consumers.
The owner modu
There is currently a race condition in the device tree part of clk_get()
function, since the pointer returned from of_clk_get_by_name() may become
invalid before __clk_get() call. E.g. due to the clock provider driver
remove() callback being called in between of_clk_get_by_name() and
__clk_get().
Add helper functions for the of_clk_providers list locking and
an unlocked variant of of_clk_get_from_provider().
These functions are intended to be used in the clkdev to avoid
race condition in the device tree based clock look up in clk_get().

The clock core code is going to be modified so clk_get() takes
reference on the clock provider module. Until the potential circular
reference issue is properly addressed, we pass NULL as the first
argument to clk_register(), in order to disallow sub-devices taking
a reference on the ISP module back
This patch series implements clock deregistration in the common clock
