clk: honor CLK_MUX_ROUND_CLOSEST in generic clk mux
CLK_MUX_ROUND_CLOSEST is part of the clk_mux documentation but clk_mux directly calls __clk_mux_determine_rate(), which overrides the flag. As result, if clk_mux is instantiated with CLK_MUX_ROUND_CLOSEST, the flag will be ignored and the clock rounded down. To solve this, this patch expose clk_mux_determine_rate_flags() in the clk-provider API and uses it in the determine_rate() callback of clk_mux. Fixes: 15a02c1f6dd7 ("clk: Add __clk_mux_determine_rate_closest") Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Stephen Boyd <sboyd@kernel.org>
