From 253795abdb04bdc762a9c2dd842ad6e549a9e2d7 Mon Sep 17 00:00:00 2001 From: Frank Oltmanns Date: Mon, 7 Aug 2023 14:43:42 +0200 Subject: [PATCH] clk: sunxi-ng: div: Support finding closest rate Add initalization macros for divisor clocks with mux (SUNXI_CCU_M_WITH_MUX) to support finding the closest rate. This clock type requires the appropriate flags to be set in the .common structure (for the mux part of the clock) and the .div part.
