- * clksel clocks are clocks that do not have a fixed parent, or that
- * can divide their parent's rate, or possibly both at the same time, based
- * on the contents of a hardware register bitfield.
- *
- * All of the various mux and divider settings can be encoded into
- * struct clksel* data structures, and then these can be autogenerated
- * from some hardware database for each new chip generation. This
- * should avoid the need to write, review, and validate a lot of new
- * clock code for each new chip, since it can be exported from the SoC
- * design flow. This is now done on OMAP4.
- *
- * The fusion of mux and divider clocks is a software creation. In
- * hardware reality, the multiplexer (parent selection) and the
- * divider exist separately. XXX At some point these clksel clocks
- * should be split into "divider" clocks and "mux" clocks to better
- * match the hardware.
- *
- * (The name "clksel" comes from the name of the corresponding
- * register field in the OMAP2/3 family of SoCs.)
- *
- * XXX Currently these clocks are only used in the OMAP2/3/4 code, but
- * many of the OMAP1 clocks should be convertible to use this
- * mechanism.
