W/O the flag, CCF would gate the mmc clocks on boot, killing the mmc controllers. CLK_IGNORE_UNUSED could be removed once the DT is fixed Changes between v2 and v3 [1]: * Split driver and header changes * Add CLK_INGORE_UNUSED flag Changes between v1 and v2 [0]: * Correct commit description and comments.

Each controller is fed by a composite clock (the usual mux, divider and gate). The muxes inputs are the xtal (default) and the fclk_div clocks. These parents, along with the divider, should be able to provide the necessary rates for mmc and nand operation. The input muxes should also be able to take mpll2, mpll3 and gp0_pll but these are precious clocks, needed for other usage. It is better if the mmc does not use these them. For this reason, mpll2, mpll3 and gp0_pll is not listed among the possible parents.
