Subject: [RFC PATCH 3/7] clk: sunxi-ng: mux: Add macro using CLK_HW_INIT_PARENTS_DATA
Date: Wed, 1 Sep 2021 00:39:47 -0500 [thread overview]
Message-ID: <20210901053951.60952-4-samuel@sholland.org> (raw)
In-Reply-To: <20210901053951.60952-1-samuel@sholland.org>
Some muxes need the flexibility to specify a combination of internal
parents (using .hw) and external parents (using .fw_name). Support
this with a version of the SUNXI_CCU_MUX_WITH_GATE macro that uses
CLK_HW_INIT_PARENTS_DATA to provide the parent information.
