Subject: [PATCH v3 7/8] clk: sunxi-ng: div: Support finding closest rate
Date: Sun, 02 Jul 2023 19:55:26 +0200	[thread overview]
Message-ID: <20230702-pll-mipi_set_rate_parent-v3-7-46dcb8aa9cbc@oltmanns.dev> (raw)
In-Reply-To: <20230702-pll-mipi_set_rate_parent-v3-0-46dcb8aa9cbc@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.
