29171344a1 clk: si514: Convert to use maple tree register cache
The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache.

62279db5a3 clk: Switch i2c drivers back to use .probe()
After commit b8a1a4cd5a ("i2c: Provide a temporary .probe_new()
call-back type"), all drivers being converted to .probe_new() and then
03c835f498 ("i2c: Switch .probe() to not take an id parameter") convert
back to (the new) .probe() to be able to eventually drop .probe_new() from
struct i2c_driver.

a7f3b6757a clk: si514: Use managed of_clk_add_hw_provider()
Use the managed `devm_of_clk_add_hw_provider()` instead of
`of_clk_add_hw_provider()`. This makes sure the provider gets automatically
removed on unbind and allows to completely eliminate the drivers `remove()`
callback.

ed5c2f5fd1 i2c: Make remove callback return void
The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

d8703ce85e clk: si514: use simple i2c probe function
The i2c probe function here doesn't use the id information provided in
its second argument, so the single-parameter i2c probe function
("probe_new") can be used instead.

This avoids scanning the identifier tables during probes.

d06e46c25a clk: si514: Migrate to clk_hw based OF and registration APIs
Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers while registering clks in
these drivers, allowing us to move closer to a clear split of
consumer and provider clk APIs.
