Subject: [PATCH v2 0/7] Add Bitmain BM1880 clock driver

Hello,

This patchset adds common clock driver for Bitmain BM1880 SoC clock
controller. The clock controller consists of gate, divider, mux
and pll clocks with different compositions. Hence, the driver uses
composite clock structure in place where multiple clocking units are
combined together.

This patchset also removes UART fixed clock and sources clocks from clock
controller for Sophon Edge board where the driver has been validated.

Thanks,
Mani

Changes in v2:

* Converted the dt binding to YAML
* Incorporated review comments from Stephen (majority of change is switching
  to new way of specifying clk parents)
