Subject: [PATCH v5 09/11] clk: sunxi-ng: div: Support finding closest rate
Date: Sun, 06 Aug 2023 15:06:54 +0200	[thread overview]
Message-ID: <20230806-pll-mipi_set_rate_parent-v5-9-db4f5ca33fc3@oltmanns.dev> (raw)
In-Reply-To: <20230806-pll-mipi_set_rate_parent-v5-0-db4f5ca33fc3@oltmanns.dev>

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.

Acked-by: Maxime Ripard <mripard@kernel.org>
