Subject: [PATCH v1 2/6] clk: sunxi-ng: div: Add macros using clk_parent_data and clk_hw
Date: Thu, 18 Nov 2021 22:35:40 -0600 [thread overview]
Message-ID: <20211119043545.4010-3-samuel@sholland.org> (raw)
In-Reply-To: <20211119043545.4010-1-samuel@sholland.org>
Referencing parents with clk_hw pointers is more efficient and removes
the dependency on global clock names. clk_parent_data is needed when
some parent clocks are provided from another driver. Add macros for
declaring dividers that take advantage of these.
