clk: gate: fix comment typo and grammar

2023-09-11T20:20:40+00:00

Change ouput -> output.

While at it change also grammatically incorrect "it's" to "its".

treewide: Remove uninitialized_var() usage

2020-07-16T19:35:15+00:00

Using uninitialized_var() is dangerous as it papers over real bugs[1]
(or can in the future), and suppresses unrelated compiler warnings
(e.g. "unused variable"). If the compiler thinks it is uninitialized,
either simply initialize the variable or make compiler changes.

In preparation for removing[2] the[3] macro[4], remove all remaining
needless uses with the following script:

git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \
	xargs perl -pi -e \
		's/\buninitialized_var\(([^\)]+)\)/\1/g;
		 s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;'

drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid
pathological white-space.

No outstanding warnings were found building allmodconfig with GCC 9.3.0
for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64,
alpha, and m68k.

clk: gate: Add support for specifying parents via DT/pointers

2020-01-07T07:10:12+00:00

After commit fc0c209c147f ("clk: Allow parents to be specified without
string names") we can use DT or direct clk_hw pointers to specify
parents. Create a generic function that shouldn't be used very often to
encode the multitude of ways of registering a gate clk with different
parent information. Then add a bunch of wrapper macros that only pass
down what needs to be passed down to the generic function to support
this with less arguments.

clk: Zero init clk_init_data in helpers

2019-11-22T23:58:04+00:00

The clk_init_data struct needs to be initialized to zero for the new
parent_map implementation to work correctly. Otherwise, the member which
is available first will get processed.

Merge branch 'clk-ti' into clk-next

2019-05-07T18:46:02+00:00

* clk-ti:
  clk: Remove CLK_IS_BASIC clk flag
  clk: ti: dra7: disable the RNG and TIMER12 clkctrl clocks on HS devices
  clk: ti: dra7x: prevent non-existing clkctrl clocks from registering
  ARM: omap2+: hwmod: drop CLK_IS_BASIC flag usage
  clk: ti: export the omap2_clk_is_hw_omap call

clk: Remove CLK_IS_BASIC clk flag

2019-04-26T17:40:49+00:00

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.

clk: core: replace clk_{readl,writel} with {readl,writel}

2019-04-23T17:57:49+00:00

Now that clk_{readl,writel} is just an alias for {readl,writel}, we can
switch all users of clk_* to use the accessors directly and remove the
helpers.
