Subject: [PATCH v1 3/6] clk: rockchip: add a COMPOSITE_DIV_OFFSET clock-type
From: Finley Xiao <finley.xiao@...k-chips.com>
The div offset of some clocks are different from their mux offset
and the COMPOSITE clock-type require that div and mux offset are
the same, so add a new COMPOSITE_DIV_OFFSET clock-type to handle that.
