Subject[PATCH v6 0/7] Add Bitmain BM1880 clock driver
Date
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 v6:

* Dropped 'clk: Warn if clk_init_data is not zero initialized' patch
* Added fixes tag to the patch adding 'clk_hw_unregister_composite'
definition
* Reworked the use of CLK_IS_CTITICAL flag from clk driver
* Removed the use of CLK_DIVIDER_HIWORD_MASK flag from driver
* Some misc cleanups to the driver
* Added Rob's reviewed tag for the binding

Changes in v5:

* Incorporated review comments from Rob on dt binding

Changes in v4:

* Fixed devicetree binding issue
* Added ARCH_BITMAIN as the default for the clk driver

Changes in v3:

* Switched to clk_hw_{register/unregister} APIs
* Returned clk_hw from the in-driver registration helpers

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)
