2013-08-16clk: export fixed-factor, gate & mux registrationMike Turquette
These registration calls may be used by loadable modules. Export them. Signed-off-by: Mike Turquette <mturquette@linaro.org>
2013-04-12clk: add device tree fixed-factor-clock binding supportGregory CLEMENT
Add support for DT "fixed-factor-clock" binding to the common fixed factor clock support. Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com> Tested-by: Christian Ruppert <christian.ruppert@abilis.com> Signed-off-by: Mike Turquette <mturquette@linaro.org>
2013-01-11clk: fixed-factor: round_rate should use do_divHaojian Zhuang
clk->rate = parent->rate / div * mult The formula is OK. But it may overflow while we do operate with unsigned long. So use do_div instead. Signed-off-by: Haojian Zhuang <haojian.zhuang@gmail.com> Signed-off-by: Mike Turquette <mturquette@linaro.org> [mturquette@linaro.org: improved $SUBJECT]
2012-07-11clk: Add CLK_IS_BASIC flag to identify basic clocksRajendra Nayak
Most platforms end up using a mix of basic clock types and some which use clk_hw_foo struct for filling in custom platform information when the clocks don't fit into basic types supported. In platform code, its useful to know if a clock is using a basic type or clk_hw_foo, which helps platforms know if they can safely use to_clk_hw_foo to derive the clk_hw_foo pointer from clk_hw. Mark all basic clocks with a CLK_IS_BASIC flag. Signed-off-by: Rajendra Nayak <rnayak@ti.com> Signed-off-by: Mike Turquette <mturquette@linaro.org>
2012-05-08clk: add a fixed factor clockSascha Hauer
Having fixed factors/dividers in hardware is a common pattern, so add a basic clock type doing this. It basically describes a fixed factor clock using a nominator and a denominator.
