[PATCH v4 05/11] clk: sunxi-ng: Add feature to find closest rate

From: Frank Oltmanns
Date: Mon Jul 17 2023 - 09:35:11 EST


The default behaviour of clocks in the sunxi-ng driver is to select a
clock rate that is closest to but less than the requested rate.

Add the CCU_FEATURE_CLOSEST_RATE flag, which can be used to allow clocks
to find the closest rate instead.
