Adds support for fixed-factor clock providers which have not been enabled via of_clk_init(). This is required by Device trees overlays that introduce clocks providers.

The only way for a fixed factor clock to change its rate would be to change its parent rate. Since passing blindly CLK_SET_RATE_PARENT might break a lot of platforms that were relying on the fact that the parent rate wouldn't change, introduce a compatible-based whitelist that will allow clocks to opt-in that flag.

Add registration APIs in the clk fixed-factor 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. Signed-off-by: NStephen Boyd <sboyd@codeaurora.org>

to_clk_*(_hw) macros have been repeatedly defined in many places. This patch moves all the to_clk_*(_hw) definitions in the common clock framework to public header clk-provider.h, and drop the local definitions.

We're removing struct clk from the clk provider API, so switch this code to using the clk_hw based provider APIs. Signed-off-by: NStephen Boyd <sboyd@codeaurora.org>

Currently it is not made explicit why clk_fixed_set_rate() can ignore its arguments and unconditionally return success. Add a comment to explain this. We also mark the clk_ops table const since it should never be modified at runtime.

由 Rajendra Nayak 提交于
Most platforms end up using a mix of basic clock types and some which use clk_hw_foo struct for filling in custom platform information when the clocks don't fit into basic types supported. In platform code, its useful to know if a clock is using a basic type or clk_hw_foo, which helps platforms know if they can safely use to_clk_hw_foo to derive the clk_hw_foo pointer from clk_hw. Mark all basic clocks with a CLK_IS_BASIC flag. Signed-off-by: NRajendra Nayak <rnayak@ti.com> Signed-off-by: NMike Turquette <mturquette@linaro.org>
