Subject: [PATCH v2 0/4] clk: mediatek: modularize COMMON_CLK_MT6779

This patch set makes COMMON_CLK_MEDIATEK and COMMON_CLK_MT6779*
be able to built as kernel modules. Necessary symbols are exported
in this patch.

In previous discussion [1], Stephen commented that there must
be a user before exporting a symbol:

"
Is the mediatek driver compilable as a module? Last time I checked it
wasn't a module. I want an upstream modular driver that uses the symbol.
Otherwise we're exporting symbols when it doesn't need to be.
"

Change since v1:
use module_platform_driver() instead of builtin_platform_driver()


Miles Chen (4):
  clk: composite: export clk_register_composite
  clk: mediatek: support COMMON_CLK_MEDIATEK module build
  clk: mediatek: support COMMON_CLK_MT6779 module build
  clk: mediatek: use tristate for COMMON_CLK_MEDAITEK and
    COMMON_CLK_MT6779
