drivers: clk: st: Add fs660c32 synthesizer algorithm

2016-09-16T23:01:38+00:00

Use an algorithm instead of a table to compute clocks for fs660c32
synthesizer.
During a video playback we need to adjust audio & video frequencies.
A table can't cover all HDMI resolutions and audio adjustment.

drivers: clk: st: Simplify clock binding of STiH4xx platforms

2016-09-16T23:01:36+00:00

This patch reworks the clock binding to avoid too much detail in DT.
Now we have only compatible string per type of clock

drivers: clk: st: Remove stih415-416 clock support

2016-09-16T23:01:34+00:00

STiH415 and STiH416 platforms are no longer used.
these platforms will be deprecated for the next kernel.

clk: st: clkgen-pll: Detect critical clocks

2016-06-30T19:17:11+00:00

Utilise the new Critical Clock infrastructure to mark clocks which
much not be disabled as CRITICAL.

Clocks are marked as CRITICAL using clk flags.  This patch also
ensures flags are peculated through the framework in the correct
manner.

Utilise the new Critical Clock infrastructure to mark clocks which
much not be disabled as CRITICAL.

While we're at it, reduce the coverage of the flex_flags variable,
since it's only really used in a single for() loop.

clk: st: Remove impossible check for of_clk_get_parent_count() < 0

2016-02-27T00:01:32+00:00

The checks for < 0 are impossible now that
of_clk_get_parent_count() returns an unsigned int. Simplify the
code and update the types.

clk: st: avoid uninitialized variable use

2016-01-30T01:20:08+00:00

My previous patch fixed some warnings about printing a couple
of variables that are always uninitialized in quadfs_pll_fs660c32_set_rate(),
but I now got a warning that only shows up in some configurations (i.e.
without gcc -Os) about the params.ndiv being used uninitialized in the
error case:

drivers/clk/st/clkgen-fsyn.c: In function 'quadfs_pll_fs660c32_set_rate':
drivers/clk/st/clkgen-fsyn.c:584:75: warning: 'params.ndiv' may be used uninitialized in this function [-Wmaybe-uninitialized]
drivers/clk/st/clkgen-fsyn.c:574:16: note: 'params.ndiv' was declared here

This changes the error handling so we bail for invalid arguments rather
than continuing with uninitialized data.
