[PATCH 5.10.y-cip 3/3] clk: renesas: rzg2l: Support sd clk mux round operation


Biju Das
 

commit 1625fbc1f73f1fa8f77c38ea554cc0b2327b156b upstream.

Currently, determine_rate() is not doing any round operation
and due to this it always selects a lower clock source compared
to the closest higher one.

Support sd clk mux round operation by passing
CLK_MUX_ROUND_CLOSEST flag to clk_mux_determine_rate_flags().
