clk: Add __clk_hw_set_clk helper function

2015-02-18T17:40:07Z

After the clk API change to return a per-user clock instance, both the struct clk_core and struct clk pointers from the hw clock needs to be assigned to clock that share the same state. In the future the struct clk_core will be removed and this is going to change again so to avoid having to change the assignments twice in all the drivers, add a helper function to have an indirection level.

clk: Add rate constraints to clocks

2015-02-02T22:23:42Z

Adds a way for clock consumers to set maximum and minimum rates. This can be used for thermal drivers to set minimum rates, or by misc. drivers to set maximum rates to assure a minimum performance level. Changes the signature of the determine_rate callback by adding the parameters min_rate and max_rate.

clk: Make clk API return per-user struct clk instances

2015-02-02T22:22:19Z

Moves clock state to struct clk_core, but takes care to change as little API as possible. struct clk_hw still has a pointer to a struct clk, which is the implementation's per-user clk instance, for backwards compatibility. The struct clk that clk_get_parent() returns isn't owned by the caller, but by the clock implementation, so the former shouldn't call clk_put() on it. Because some boards in mach-omap2 still register clocks statically, their clock registration had to be updated to take into account that the clock information is stored in struct clk_core now.

clk: divider: Make generic for usage elsewhere

2015-01-27T19:48:52Z

Some devices don't use mmio to interact with dividers. Split out the logic from the register read/write parts so that we can reuse the division logic elsewhere. Signed-off-by: Stephen Boyd Tested-by: Kenneth Westfield Signed-off-by: Michael Turquette

clk: Add __clk_mux_determine_rate_closest

2015-01-27T19:48:39Z

Some clock drivers want to find the closest rate on the input of a mux instead of a rate that's less than or equal to the desired rate. Add a generic mux function to support this. Signed-off-by: Stephen Boyd Tested-by: Kenneth Westfield Signed-off-by: Michael Turquette

clk: Add clk_unregister_{divider, gate, mux} to close memory leak

2015-01-17T21:52:41Z

The common clk_register_{divider,gate,mux} functions allocated memory for internal data which wasn't freed anywhere. Drivers using these helpers could only unregister clocks but the memory would still leak. Add corresponding unregister functions which will release all resources.
