2017-12-06clk: SPEAr: pr_err() strings should end with newlinesArvind Yadav
pr_err() messages should end with a new-line to avoid other messages being concatenated. Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>

2017-11-13clk: spear: Delete error messages for failed memory allocationsMarkus Elfring
Omit extra messages for a memory allocation failure in these functions. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
2017-11-01clk: spear: make clk_ops constBhumika Goyal
Make these const as they are only stored in the const field of a clk_init_data structure. Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>

2012-05-12SPEAr: clk: Add Fractional Synthesizer clockViresh Kumar
All SPEAr SoC's contain Fractional Synthesizers. Their Fout is derived from following equations: Fout = Fin / (2 * div) (division factor) div is 17 bits:- 0-13 (fractional part) 14-16 (integer part) div is (16-14 bits).(13-0 bits) (in binary) Fout = Fin/(2 * div) Fout = ((Fin / 10000)/(2 * div)) * 10000 Fout = (2^14 * (Fin / 10000)/(2^14 * (2 * div))) * 10000 Fout = (((Fin / 10000) << 14)/(2 * (div << 14))) * 10000 div << 14 is simply 17 bit value written at register. This patch adds in support for this type of clock. Signed-off-by: Viresh Kumar <viresh.kumar@st.com> Reviewed-by: Mike Turquette <mturquette@linaro.org>
