We don't want clk provider drivers to use the init structure after clk registration time, but we leave a dangling reference to it by means of clk_hw::init. Let's overwrite the member with NULL during clk_register() so that this can't be used anymore after registration time.

Introduce the clk_hw_set_parent() provider call to change parent of a clock by using the clk_hw pointers. This eases the clock reparenting from clock rate notifiers and implementing DVFS with simpler code avoiding the boilerplates functions as __clk_lookup(clk_hw_get_name()) then clk_set_parent().

With the new clk parenting code, clk_init_data was expanded to include .parent_data, for clk drivers to specify parents using a combination of device tree clock-names, pointers to struct clk_hw, device tree clocks, and/or fallback global clock names. Add a new macro, CLK_FIXED_FACTOR_FW_NAME, that takes a string to match a clock-names entry in the device tree to specify the clock parent. Signed-off-by: Chen-Yu Tsai <wens@csie.org>
With the new clk parenting code, clk_init_data was expanded to include .parent_hws, for clk drivers to directly reference parents by clk_hw. Add a new macro, CLK_FIXED_FACTOR_HWS, that can take an array of pointers to struct clk_hw, instead of a string, as its parent. Taking an array instead of a direct pointer allows the reuse of the array for multiple clks, rather than having one compound literal with the same contents allocated for each clk declaration.
