      clk: gpio: Unlock mutex on error path · c5e857a4
      Stephen Boyd authored 
      We don't unlock the mutex if we fail to allocate the parent names
array. Unlock it and return an error in this case as well.

      clk: h8300: Use standard Linux I/O accessors · 006cb8b6
      Stephen Boyd authored 
      There doesn't seem to be any reason why we can't use the standard
readb()/writeb() accessors here because ctrl_inb() and
ctrl_outb() match the generic implementation of readb() and
writeb() that the h8300 architecture uses. This allows us to test
compile this driver on other architectures besides h8300.

      clk: h8300: Drop allocation printk and cleanup sizeof style · 9298f026
      Stephen Boyd authored 
      We don't need to print an error on allocation failures, drop it.
While we're here, change the sizeof() to be sizeof(*<ptr>) to
make code more future proof.

      clk: fix some determine_rate implementations · 57d866e6
      Boris Brezillon authored 
      Some determine_rate implementations are not returning an error
when they failed to adapt the rate according to the rate request.
Fix them so that they return an error instead of silently
returning 0.

      clk: change clk_ops' ->determine_rate() prototype · 0817b62c
      Boris Brezillon authored 
      Clock rates are stored in an unsigned long field, but ->determine_rate()
(which returns a rounded rate from a requested one) returns a long
value (errors are reported using negative error codes), which can lead
to long overflow if the clock rate exceed 2Ghz.

Change ->determine_rate() prototype to return 0 or an error code, and pass
a pointer to a clk_rate_request structure containing the expected target
rate and the rate constraints imposed by clk users.

The clk_rate_request structure might be extended in the future to contain
other kind of constraints like the rounding policy, the maximum clock
inaccuracy or other things that are not yet supported by the CCF
(power consumption constraints ?).
