Subject: [PATCH v4 0/8] Add Bitmain BM1880 clock driver
Date: Thu, 22 Aug 2019 22:54:18 +0530 [thread overview]
Message-ID: <20190822172426.25879-1-manivannan.sadhasivam@linaro.org> (raw)
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 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)
Manivannan Sadhasivam (8):
clk: Zero init clk_init_data in helpers
clk: Warn if clk_init_data is not zero initialized
clk: Add clk_hw_unregister_composite helper function definition
