clk: divider: Add re-usable determine_rate implementations

2021-06-30T18:37:02Z

These are useful when running on 32-bit systems to increase the upper supported frequency limit. clk_ops.round_rate returns a signed long which limits the maximum rate on 32-bit systems to 2^31 (or approx. 2.14GHz). clk_ops.determine_rate internally uses an unsigned long so the maximum rate on 32-bit systems is 2^32 or approx. 4.29GHz. To avoid code-duplication switch over divider_{ro_,}round_rate_parent to use the new divider_{ro_,}determine_rate functions.

clk: fixed: add devm helper for clk_hw_register_fixed_factor()

2021-02-14T20:37:48Z

Add a devm helper for clk_hw_register_fixed_factor() so that drivers that internally register fixed factor clocks for things like dividers don't need to manually unregister them on remove or if probe fails.

clk: add api to get clk consumer from clk_hw

2020-11-14T20:56:57Z

clk_register() is deprecated. Using 'clk' member of struct clk_hw is discouraged. With this constraint, it is difficult for driver to register clocks using the clk_hw API and then use the clock with the consumer API This adds a simple helper, clk_hw_get_clk(), to get a struct clk from a struct clk_hw. Like other clk_get() variant, each call to this helper must be balanced with a call to clk_put(). To make life easier on the consumers, a memory managed version is provided as well.

clk: drop unused function __clk_get_flags

2020-08-03T20:53:34Z

The function __clk_get_flags has not been used since the April 2019 commit a348f05361c9 ("ARM: omap2+: hwmod: drop CLK_IS_BASIC flag usage"). Other uses were removed in June 2015, eg by commit 98d8a60eccee ("clk: Convert __clk_get_flags() to clk_hw_get_flags()"), which shows how clk_hw_get_flags can easily be used instead.
