Lars-Peter Clausen 56fc9a343a clk: lmk04832: 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.

spi: make remove callback a void function
The value returned by an spi 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.

Liam Beguin 284c537a8a clk: lmk04832: drop redundant fallthrough statements
When the body of a case statement is empty, it is well understood that
it is intentional and explicit fallthrough statements are not required.
Drop them.

Wang Hai b424f73b6c clk: lmk04832: fix return value check in lmk04832_probe()
In case of error, the function devm_kzalloc() and devm_kcalloc() return
NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check
should be replaced with NULL test.

Liam Beguin 6181baa177 clk: lmk04832: add support for digital delay
The digital delay allows outputs to be delayed from 8 to 1023 VCO
cycles. The delay step can be as small as half the period of the clock
distribution path. For example, a 3.2-GHz VCO frequency results in
156.25-ps steps.  The digital delay value takes effect on the clock
output phase after a SYNC event.

This is required to support JESD204B subclass 1.
