      clk: fixed-rate: Add hw based registration APIs · 26ef56be
      Stephen Boyd authored 
      Add registration APIs in the clk fixed-rate code to return struct
clk_hw pointers instead of struct clk pointers. This way we hide
the struct clk pointer from providers unless they need to use
consumer facing APIs.

      clkdev: Add clk_hw based registration APIs · e4f1b49b
      Stephen Boyd authored 
      Now that we have a clk registration API that doesn't return
struct clks, we need to have some way to hand out struct clks via
the clk_get() APIs that doesn't involve associating struct clk
pointers with a struct clk_lookup. Luckily, clkdev already
operates on struct clk_hw pointers, except for the registration
facing APIs where it converts struct clk pointers into struct
clk_hw pointers almost immediately.

Let's add clk_hw based registration APIs so that we can skip the
conversion step and provide a way for clk provider drivers to
operate exclusively on clk_hw structs. This way we clearly
split the API between consumers and providers.

      clk: Add clk_hw OF clk providers · 0861e5b8
      Stephen Boyd authored 
      Now that we have a clk registration API that doesn't return
struct clks, we need to have some way to hand out struct clks via
the clk_get() APIs that doesn't involve associating struct clk
pointers with an OF node. Currently we ask the OF provider to
give us a struct clk pointer for some clkspec, turn that struct
clk into a struct clk_hw and then allocate a new struct clk to
return to the caller.

Let's add a clk_hw based OF provider hook that returns a struct
clk_hw directly, so that we skip the intermediate step of
converting from struct clk to struct clk_hw. Eventually when
we've converted all OF clk providers to struct clk_hw based APIs
we can remove the struct clk based ones.

It should also be noted that we change the onecell provider to
have a flex array instead of a pointer for the array of clk_hw
pointers. This allows providers to allocate one structure of the
correct length in one step instead of two.

      clk: Add {devm_}clk_hw_{register,unregister}() APIs · 4143804c
      Stephen Boyd authored 
      We've largely split the clk consumer and provider APIs along
struct clk and struct clk_hw, but clk_register() still returns a
struct clk pointer for each struct clk_hw that's registered.
Eventually we'd like to only allocate struct clks when there's a
user, because struct clk is per-user now, so clk_register() needs
to change.

Let's add new APIs to register struct clk_hws, but this time
we'll hide the struct clk from the caller by returning an int
error code. Also add an unregistration API that takes the clk_hw
structure that was passed to the registration API. This way
provider drivers never have to deal with a struct clk pointer
unless they're using the clk consumer APIs.

      clk: rockchip: drop unnecessary header comment · 2b4e6286
      Heiko Stuebner authored 
      The internal clk header did contain a comment indicating that some of the
defined registers were shared over multiple clock controller variants.
In recent times, it was simply extended all the time and stopped providing
any meaningful information, so drop it and it's overlong line.

      clk: rockchip: reign in some overly long lines in the rk3399 controller · 995d3fde
      Heiko Stuebner authored 
      We allow overlong lines in the array portitions describing the clock
trees to ease readability by having each element always at the same
position. But the rest of the code should honor the 80 char limit.

Fix the newly added rk3399 clock code to respect that.
