The patchset is the 2nd round of update to the meson gxbb clock controller
to add initial audio support. The patchset is based on clk-next.
There is not much out of the ordinary here (adding new clocks and exposing
them) except maybe for 2 patches:
Patch #2: Adds a safety check while registering clocks to protect against
holes in clk_hw_onecell_data, if it ever happens. Same thing is
done for the meson8b clock controller.
Patch #3: Adds a new clock divider driver to implement the necessary
policy for the i2s master clock (see patch changelog)
This patchset has been test on the gxbb p200 and gxl p230.
Changes since v1 [0]:
- fix typo and use clamp function in patch #3
