clk: qcom: Add rcg ops to return floor value closest to the requested rate
The default behaviour with clk_rcg2_ops is for the clk_round_rate()/clk_set_rate() to return/set a ceil clock rate closest to the requested rate by looking up the corresponding frequency table. However, we do have some instances (mainly sdcc on various platforms) of clients expecting a clk_set_rate() to set a floor value instead. Add a new clk_rcg2_floor_ops to handle this for such specific rcg instances Signed-off-by: Rajendra Nayak <rnayak@codeaurora.org> Signed-off-by: Ritesh Harjani <riteshh@codeaurora.org> Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
