clk: bm1880: remove MODULE_LICENSE in non-modules

2023-04-13T20:13:50+00:00

Since commit 8b41fc4454e ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.

So remove it in the files in this commit, none of which can be built as
modules.

clk: bm1880: remove kfrees on static allocations

2022-01-07T01:46:56+00:00

bm1880_clk_unregister_pll & bm1880_clk_unregister_div both try to
free statically allocated variables, so remove those kfrees.

For example, if we take L703 kfree(div_hw):
- div_hw is a bm1880_div_hw_clock pointer
- in bm1880_clk_register_plls this is pointed to an element of arg1:
  struct bm1880_div_hw_clock *clks
- in the probe, where bm1880_clk_register_plls is called arg1 is
  bm1880_div_clks, defined on L371:
  static struct bm1880_div_hw_clock bm1880_div_clks[]

clk: bm1800: Remove set but not used variable 'fref'

2019-12-24T08:10:33+00:00

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/clk/clk-bm1880.c: In function 'bm1880_pll_rate_calc':
drivers/clk/clk-bm1880.c:477:13: warning:
 variable 'fref' set but not used [-Wunused-but-set-variable]

It is never used, so remove it.

clk: Add common clock driver for BM1880 SoC

2019-11-22T23:58:27+00:00

Add common clock driver for Bitmain BM1880 SoC. The clock controller on
BM1880 has supplies clocks to all peripherals in the form of gate clocks
and composite clocks (fixed factor + gate).
