Sorry for my previous mail, I sent it as HTML and also top posted.

Don't these clks already exist (e.g. > SCLK_SDMMC)? I actually need to control 2 phases, one of them is used when outputting data, the other when sampling. Sunxi does something similar: http://lists.infradead.org/pipermail/linux-arm-kernel/2014-July/273273.html Another reason it wouldn't work is because the upstream clock(eg SCLK_SDMMC) is twice as fast as the real clock(see RK3288_CLKGEN_DIV in drivers/mmc/host/dw_mmc-rockchip.c), since that clock goes to a /2 divider to be able to do the 90 degree clock phases.
