This patchset adds support for GFM Muxes found in LPASS
(Low Power Audio SubSystem) IP in Audio Clock Controller
and Always ON clock controller.

Clocks derived from these muxes are consumed by LPASS Digital Codec.
Currently the driver for Audio and Always ON clock controller only
supports GFM Muxes, however it should be easy to add more clock
support when required

Changes since v2:
- updated Kconfig text and help as suggested by Stephen
- removed unnecessary header file include
- use fw_name instead of name for parents
- use devm_platform_ioremap_resource

verified dt_binding_check to pass on linux master,

Srinivas Kandagatla (4):
  dt-bindings: clock: Add support for LPASS Audio Clock Controller
  dt-bindings: clock: Add support for LPASS Always ON Controller
  clk: qcom: Add support to LPASS AUDIO_CC Glitch Free Mux clocks
  clk: qcom: Add support to LPASS AON_CC Glitch Free Mux clocks

Which linux master? Can you try on linux-next?
