These macros are used by more than one SoC vendor platforms, avoid to have many copies of these code, this patch moves them to the common clock directory which every clock drivers can access to. Signed-off-by: Chunyan Zhang <chunyan.zhang@spreadtrum.com> --- This patchset also added a few common clock mactos into drivers/clk/clk_common.h, which are generally useful for all vendors' clock driver, sunxi-ng, zte, sprd (added in this patchse) use them (or part of them) at present, once this patch is merged, I can help to remove the duplicated code which is under the vendors' respective directories. --- drivers/clk/clk_common.h | 60 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 60 insertions(+) create mode 100644 drivers/clk/clk_common.h
