2019-05-01clk: sprd: Use the correct style for SPDX License IdentifierNishad Kamdar
This patch corrects the SPDX License Identifier style in header files related to Clock Drivers for Spreadtrum SoCs. For C header files Documentation/process/license-rules.rst mandates C-like comments (opposed to C source files where C++ style should be used) Changes made by using a script provided by Joe Perches here: https://lkml.org/lkml/2019/2/7/46 Suggested-by: Joe Perches <joe@perches.com> Signed-off-by: Nishad Kamdar <nishadkamdar@gmail.com> Signed-off-by: Stephen Boyd <sboyd@kernel.org>
2018-03-16clk: sprd: add RTC gate for SC9860Chunyan Zhang
Add a few gate clocks which are used for gating RTC for some devices on AON area of SC9860. This patch has been tested on SC9860, with this patch and proper DT configurations, the watchdog can be initialized and work well.

2018-01-26Merge branch 'clk-divider-container' into clk-nextStephen Boyd
* clk-divider-container: clk: divider: fix incorrect usage of container_of Plus fixup sprd/div.c to pass the width too.
2017-12-21clk: sprd: add clocks support for SC9860Chunyan Zhang
This patch added the list of clocks for Spreadtrum's SC9860 SoC, together with clock initialization code. Signed-off-by: Chunyan Zhang <chunyan.zhang@spreadtrum.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2017-12-21clk: sprd: add adjustable pll supportChunyan Zhang
Introduced a common adjustable pll clock driver for Spreadtrum SoCs. Signed-off-by: Chunyan Zhang <chunyan.zhang@spreadtrum.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2017-12-21clk: sprd: add composite clock supportChunyan Zhang
This patch introduced composite driver for Spreadtrum's SoCs. The functions of this composite clock simply consist of divider and mux clocks. Signed-off-by: Chunyan Zhang <chunyan.zhang@spreadtrum.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2017-12-21clk: sprd: add divider clock supportChunyan Zhang
This is a feature that can also be found in sprd composite clocks, provide a bunch of helpers that can be reused later on. Signed-off-by: Chunyan Zhang <chunyan.zhang@spreadtrum.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2017-12-21clk: sprd: add mux clock supportChunyan Zhang
This patch adds clock multiplexor support for Spreadtrum platforms, the mux clocks also can be found in sprd composite clocks, so provides two helpers that can be reused later on. Signed-off-by: Chunyan Zhang <chunyan.zhang@spreadtrum.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2017-12-21clk: sprd: add gate clock supportChunyan Zhang
Some clocks on the Spreadtrum's SoCs are just simple gates. Add support for those clocks. Signed-off-by: Chunyan Zhang <chunyan.zhang@spreadtrum.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2017-12-21clk: sprd: Add common infrastructureChunyan Zhang
Added Spreadtrum's clock driver framework together with common structures and interface functions. Signed-off-by: Chunyan Zhang <chunyan.zhang@spreadtrum.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
