2015-07-28clk: socfpga: switch to GENMASK()Andy Shevchenko1-1/+1
Convert the code to use GENMASK() helper instead of div_mask() macro. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Acked-by: Dinh Nguyen <dinguyen@opensource.altera.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2015-07-20clk: socfpga: Remove clk.h and clkdev.h includesStephen Boyd1-2/+1
Clock provider drivers generally shouldn't include clk.h because it's the consumer API. Remove the include here because this is a provider driver. The clkdev.h include isn't used either, remove it and add in slab.h to make sure things keep compiling.

2015-06-05clk: socfpga: make use of of_clk_parent_fill helper functionDinh Nguyen1-5/+1
Use of_clk_parent_fill to fill in the parent clock's array. Signed-off-by: Dinh Nguyen <dinguyen@opensource.altera.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2015-05-21clk: socfpga: update clk.h so for Arria10 platform to useDinh Nguyen1-4/+0
There are 5 possible parent clocks for the SoCFPGA Arria10. Move the define SYSMGR_SDMMC_CTRL_SET and streq() to clk.h so that the Arria clock driver can use. Signed-off-by: Dinh Nguyen <dinguyen@opensource.altera.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>

drivers/clk/socfpga/clk-gate.c:227:40: warning: Using plain integer as NULL pointer Cc: Dinh Nguyen <dinguyen@altera.com> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2014-05-12clk: socfpga: add divider registers to the main pll outputsDinh Nguyen1-1/+0
The C0(mpu_clk), C1(main_clk), and C2(dbg_base_clk) outputs from the main PLL go through a pre-divider before coming into the system. These registers were hidden for the CycloneV platform, but are now used for the ArriaV platform. This patch updates the clock driver to read the div-reg property for the socfpga-periph-clk clocks. Also moves the div_mask define to clk.h for re-use. Signed-off-by: Dinh Nguyen <dinguyen@altera.com>
2014-02-18clk: socfpga: Add a clk-phase property to the "altr,socfpga-gate-clk"Dinh Nguyen1-0/+68
The clk-phase property is used to represent the 2 clock phase values that is needed for the SD/MMC driver. Add a prepare function to the clk_ops, that will use the syscon driver to set sdmmc_clk's phase shift that is located in the system manager. Signed-off-by: Dinh Nguyen <dinguyen@altera.com> Acked-by: Zhangfei Gao <zhangfei.gao@linaro.org> Acked-by: Jaehoon Chung <jh80.chung@samsung.com> --- v9: none v8: Use degrees in the clk-phase binding property v7: Add dts property to represent the clk phase of the sdmmc_clk. Add a prepare function to the gate clk that will toggle clock phase setting. Remove the "altr,socfpga-sdmmc-sdr-clk" clock type. v6: Add a new clock type "altr,socfpga-sdmmc-sdr-clk" that will be used to set the phase shift settings. v5: Use the "snps,dw-mshc" binding v4: Use the sdmmc_clk prepare function to set the phase shift settings v3: Not use the syscon driver because as of 3.13-rc1, the syscon driver is loaded after the clock driver. v2: Use the syscon driver
2014-02-18clk: socfpga: split clk codeSteffen Trumtrar1-0/+195
Move the different kinds of clocks into their own files. The reason is to aid readability of the code. This also goes along with the other SoC-specific clock drivers. The split introduces new structs for the three types of clocks and uses them. Other changes are not done to the code.
