8e842f02af clk: at91: clk-master: remove dead code
Commit facb87ad75 ("clk: at91: sama7g5: remove prescaler part of master
clock") removed the master clock's prescaler from clock tree of SAMA7G5
as it has been discovered that there is a hardware bug when trying to
change it at run-time (bug is described in description of
commit facb87ad75 ("clk: at91: sama7g5: remove prescaler part of master
clock")). This was previously changed at CPUFreq driver request. Thus, with
commit facb87ad75 ("clk: at91: sama7g5: remove prescaler part of master
clock") there is no need of code that handles run-time changes of master
clock's prescaler, thus remove this code.

d54bb86b89 clk: mediatek: Warn if clk IDs are duplicated
The Mediatek clk driver library handles duplicate clock IDs in two
different ways: either ignoring the duplicate entry, or overwriting
the old clk. Either way may cause unexpected behavior, and the latter
also causes an orphan clk that cannot be cleaned up.

Align the behavior so that later duplicate entries are ignored, and
a warning printed. The warning will also aid in making the issue
noticeable.

mtk_clk_simple_probe() as their driver probe function.

Now that we have a matching remove function, hook it up for the relevant

3c3ba2ab02 clk: mediatek: mtk: Implement error handling in register APIs
The remaining clk registration functions do not stop or return errors
if any clk failed to be registered, nor do they implement error
handling paths. This may result in a partially working device if any
step fails.

Make the register functions return proper error codes, and bail out if
errors occur. Proper cleanup, i.e. unregister any clks that were
successfully registered, is done in the new error path.

This also makes the |struct clk_data *| argument mandatory, as it is
used to track the list of clks registered.

19b8d43887 clk: mediatek: gate: Consolidate gate type clk related code
Right now some bits of the gate type clk code are in clk-gate.[ch], but
other bits are in clk-mtk.[ch]. This is different from the cpumux and
mux type clks, for which all of the code are found in the same files.

Move the functions that register multiple clks from a given list,
mtk_clk_register_gates_with_dev() and mtk_clk_register_gates(), to
clk-gate.[ch] to consolidate all the code for the gate type clks.

This commit only moves code with minor whitespace fixups to correct
the code style. Further improvements, such as internalizing various
functions and structures will be done in later commits.
