clk: Revise help text for clk_get_parent_rate()

2024-08-01T21:33:19+00:00

The function returns the rate of the parent clock, the previous text
made no sense at all.

clk: Remove rfree

Nothing uses this function. Remove it. Since clk_free no longer does
anything, just stub it out.

After introducing dump to clk_ops there is no need to override or expose

clk: also handle ENOENT in *_optional functions

2023-11-01T19:14:51+00:00

If the device does not specify any clocks in device tree, these
functions will return PTR_ERR(-ENOENT). This is not the intended
behavior and does not comply with linux kernel CCF. Fix that by
returning NULL under such circumstances instead.

clk: fix count parameter type for clk_release_all

2023-11-01T19:13:55+00:00

The second parameter for clk_release_all is used as an unsigned
(which makes sense) but the function prototype declares it as an int.
This causes warnings/error like such below:

include/clk.h:422:48: error: conversion to ‘int’ from ‘unsigned int’ may change the sign of the result [-Werror=sign-conversion]
  422 |         return clk_release_all(bulk->clks, bulk->count);

To fix this, changed the type of the count to `unsigned int`

This allows devm_clock_get(dev, NULL) to work and get the first clock,

Clock patches for 2023.01

This contains various fixes (some long overdue) for the next release.

clk: change return type of clk_get_parent_rate from long long to ulong

2022-10-19T16:06:41+00:00

All functions getting and setting clock rate use ulong for rate, only
clk_get_parent_rate is an exception. Change the return value to match
other clock rate funcrions.

Most users directly assign the rate to unsigned long anyway, and the few
users that use u64 (not s64) multiply the rate so they may need the
extra bits for the result in their use case.
