2021-09-02Merge branch 'clk-frac-divider' into clk-nextStephen Boyd1-3/+9
- Add power of two flag to fractional divider clk type * clk-frac-divider: clk: fractional-divider: Document the arithmetics used behind the code clk: fractional-divider: Introduce POWER_OF_TWO_PS flag clk: fractional-divider: Hide clk_fractional_divider_ops from wide audience clk: fractional-divider: Export approximation algorithm to the CCF users
2021-08-12clk: fractional-divider: Introduce POWER_OF_TWO_PS flagAndy Shevchenko1-0/+7
The newly introduced POWER_OF_TWO_PS flag, when set, makes the flow to skip the assumption that the caller will use an additional 2^scale prescaler to get the desired clock rate.

2021-08-06clk: Align provider-specific CLK_* bit definitionsGeert Uytterhoeven1-5/+5
The definition of CLK_MULTIPLIER_ROUND_CLOSEST is not aligned to the two bit definitions next to it. A deeper inspection reveals that the alignment of CLK_MULTIPLIER_ROUND_CLOSEST does match the most common alignment. Align the bit definitions for the various provider types throughout the file at 40 columns, to increase uniformity.

2021-06-30clk: divider: Add re-usable determine_rate implementationsMartin Blumenstingl1-0/+6
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.

2020-11-14clk: add api to get clk consumer from clk_hwJerome Brunet1-0/+5
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.

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.

2019-11-11clk: Add API to get index of the clock parentSowjanya Komatineni1-0/+1
This patch adds a new clk_hw_get_parent_index() function that can be used to retrieve the index of a given clock's parent. This can be useful for restoring a clock on system resume.

2019-08-16clk: Overwrite clk_hw::init with NULL during clk_register()Stephen Boyd1-1/+2
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.

2019-04-26clk: Remove CLK_IS_BASIC clk flagStephen Boyd1-1/+1
This flag was historically used to indicate that a clk is a "basic" type of clk like a mux, divider, gate, etc. This never turned out to be very useful though because it was hard to cleanly split "basic" clks from other clks in a system. This one flag was a way for type introspection and it just didn't scale. If anything, it was used by the TI clk driver to indicate that a clk_hw wasn't contained in the SoC specific clk structure. We can get rid of this define now that TI is finding those clks a different way.
